what is the solution to the equation x/2-4=6​

Answer:

C

Step-by-step explanation:

Using the laws of logarithms

• log x + log y ⇔ log(xy)

• log x = log y ⇒ x = y

Given

logx + log(x - 3) = log 3x

log x(x - 3) = log 3x, hence

x(x - 3) = 3x

x² - 3x = 3x ( subtract 3x from both sides )

x² - 6x = 0 ← factor out x from each term

x(x - 6) = 0

Equate each factor to zero and solve for x

x = 0

x - 6 = 0 ⇒ x = 6

Solutions are x = 0, x = 6 → C

Answer: OPTION A

Step-by-step explanation:

You need to remember the logarithms properties:

[tex]log(a)+log(b)=log(ab)\\\\log(a)-log(b)=log(\frac{a}{b})\\\\log(a)^b=b*log(a)[/tex]

Rewrite the equation:

[tex]log(x(x-3))=log(3)+log(x)[/tex]

Like this logarithm has base 10, you can make this procedure:

[tex]log(x(x-3))-log(x)=log(3)[/tex]

[tex]log\frac{(x(x-3))}{(x)}=log(3)[/tex]

[tex]log(x-3)=log(3)[/tex]

[tex]10^{log((x-3))}=10^{log(3)}[/tex]

Then:

[tex](x-3)=3[/tex]

Now you need to solve for the variable "x":

[tex]x=3+3\\x=6[/tex]

Answer:

C) 8+x > 10

Step-by-step explanation:

I think C is the correct answer because it's an open circle, it can't equal to 2 and it must be higher than 2.

Answer:-

Q no.8 :

9, 13, 17 can merely be the correct option.

Explanation:-

• The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.

For instance:-

1) Calculation: 9 + 13 = 22 which is greater than the third side (the hypotenuse) that was 17. And hence is correct.

2) Calculation: 10 + 10 = 20 which is equal to the third/hypotenuse side that was also 20. Therefore it doesn’t fit the theorem and is unable to form a triangle.

3)Calculation: 6+8 = 14 which is less than the greatest/hypotenuse/third side or the side of measure 15. Thence, it isn’t the correct also. No accurate triangle can be formed from all these(6, 8, 15) measurements.

4) Calculation: 2+3 = 6 which is equal to the third /hypotenuse side of measure 6 also. And therefrom no triangle can be constructed from the given sides(2, 3, 6).

• The third important property of triangles is the triangle inequality rule, which states:

“The length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides”.

(Note: I honestly prefer you to understand from the first point which is far much clearer than the second one).

Answer:

centre = (2, 4)

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² - 4x - 8y - 5 = 0

Rearrange the x/y terms together and add 5 to both sides

x² - 4x + y² - 8y = 5

Use the method of completing the square on both the x/y terms

add ( half the coefficient of the x/y terms )² to both sides

x² + 2(- 2)x + 4 + y² + 2(- 4)y + 16 = 5 + 4 + 16

(x - 2)² + (y - 4)² = 25 ← in standard form

with centre (2, 4) and r = [tex]\sqrt{25}[/tex] = 5

Answer:

2, 6, 12, 20, 30

Step-by-step explanation:

To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the rule

a₁ = 1² + 1 = 1 + 1 = 2

a₂ = 2² + 2 = 4 + 2 = 6

a₃ = 3² + 3 = 9 + 3 = 12

a₄ = 4² + 4 = 16 + 4 = 20

a₅ = 5² + 5 = 25 + 5 = 30

Answer: x=5√3(you've got it correct!)

y=15

In∆ADC,

Cos 60°=DC/10

DC=5

y=20-5

y=15

Answer:

Step-by-step explanation:

Look at the picture.

ΔABC, ΔDBA and ΔDAC are the triangles 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

Therefore

DC : AD : AC = 1 : √3 : 2

If AC = 10, then DC = 10 : 2 = 5 and AD = x = 5√3

AD : BD : AB =  1 : √3 : 2

If AD = 5√3, then AB = 2 · 5√3 = 10√3 and BD = y = 5√3 · √3 = 5 · 3 = 15

Answer:

139 and 59, respectively

Step-by-step explanation:

By definition, supplementary means that the angles all add up to equal 180 degrees.  Therefore, 180 - 41 = 139.

By definition, complementary means that the angles all add up to equal 90 degrees.  Therefore, 90 - 31 = 59.

Answer: 68%

Step-by-step explanation:

Answer:

2a² + 5a - 3 = (2a - 1)(a + 3)

2a² - a - 3 = (2a - 3)(a + 1)

2a² - 5a - 3 = (2a + 1)(a - 3)

2a² + a - 3 = (2a + 3)(a - 1)

Step-by-step explanation:

* To factor a trinomial in the form ax² ± bx ± c:

- Look at the c term

# If the c term is positive

∵ c = r × s ⇒ r and s are the factors of c

∴ r and s will have the same sign (sign of b)

∵ a = h × k ⇒ h , k are the factors of a

∴ rk + hs = b

∴ (hx + r)(kx + s) ⇒ if b +ve  OR  (hx - r)(kx - s) ⇒ if b -ve

# If the c term is negative

∵ c = r × s ⇒ r and s are the factors of c

∴ r and s will not have the same sign

∵ a = h × k ⇒ h and k are the factors of a

∴ rk - hs = b OR hs - rk = b

(hx + r)(kx - s) OR (hx - r)(kx + s)

* Now lets solve the problem

∵ 2a² + 5a - 3

∴ c = -3 ⇒ -ve term

∴ r , s have different sign

∵ 3 = 1 × 3 then r = 1 , s = 3

∵ a = 2

∵ a = h × k

∵ 2 = 2 × 1 then h = 2 , k = 1

∵ rk = 1

∵ sh = 6

∴ sh - rk = 5 ⇒ same value of b

∵ (hx - r)(kx + s)

∴ 2a² + 5a - 3 = (2a - 1)(a + 3)

∵ 2a² - a - 3

∴ c = -3 ⇒ -ve term

∴ r , s have different sign

∵ 3 = 3 × 1 then r = 3 , s = 1

∵ a = 2

∵ a = h × k

∵ 2 = 2 × 1 then h = 2 , k = 1

∵ rk = 3

∵ sh = 2

∴ sh - rk = -1 ⇒ same value of b

∵ (hx - r)(kx + s)

∴ 2a² - a - 3 = (2a - 3)(a + 1)

∵ 2a² - 5a - 3

∴ c = -3 ⇒ -ve term

∴ r , s have different sign

∵ 3 = 1 × 3 then r = 1 , s = 3

∵ a = 2

∵ a = h × k

∵ 2 = 2 × 1 then h = 2 , k = 1

∵ rk = 1

∵ sh = 6

∴ rk - hs = -5 ⇒ same value of b

∵ (hx + r)(kx - s)

∴ 2a² - 5a - 3 = (2a + 1)(a - 3)

∵ 2a² + a - 3

∴ c = -3 ⇒ -ve term

∴ r , s have different sign

∵ 3 = 3 × 1 then r = 3 , s = 1

∵ a = 2

∵ a = h × k

∵ 2 = 2 × 1 then h = 2 , k = 1

∵ rk = 3

∵ sh = 2

∴ rk - sh = 1 ⇒ same value of b

∵ (hx + r)(kx - s)

∴ 2a² + a - 3 = (2a + 3)(a - 1)

Answer: The answer to your question is 20

Step-by-step explanation: We know that 3 out of every 5 picks are oranges. And if the next 12 picks are orange, what is the total number of oranges in all?

So first, you would set up a proportion, which would look like this:

3 oranges/ 5 picks = 12 oranges/ x picks

Let the number of picks be known as x, our variable, since we don't know how many oranges are there total.

Next, when you have a proportion that you are trying to solve, the best thing to do is cross multiply, which will look this:

3x = 12(5)

3x = 60

3x/3 = 60/3

x=20 picks

Therefore, the answer is 20 picks

Answer:

The formula for the volume of a cylinder is:

V= pi * radius^2 * height

When the values are plugged in, you would have:

Then simplified....

V= pi * 49 * 14

V= pi * 686

V= 2155.13256036

and when rounded to the nearest inch...

the volume would be approximately 2155 inches.

Answer:

The slope of the line is 77

Explanation:

We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.

The slope can, therefore, be calculated as follows:

[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁ , y₁) and (x₂ , y₂) are two points on the line

We are given that the two points (1, 123) and (3, 277) are two points in the line

Substitute with them in the above equation to get the slope as follows:

[tex]slope = \frac{277-123}{3-2}=77[/tex]

Hope this helps :)

The slope of a line represents the rate of change between two variables. The value of the slope in this scenario is 77/2.

The slope of a line represents the rate of change between two variables. In this case, the slope can be calculated using the formula:

slope = (change in y) / (change in x).

Given the points (1,123) and (3,277), the slope can be calculated as follows:

slope = (277 - 123) / (3 - 1).

Therefore, the value of the slope of the line representing the Morales family's mile-marker locations over time is 77/2.

A midpoint.

It is a set of points (single point) that is equidistant from point A and point B.

In other words the distance between point A and midpoint M is equal to the distance between point M and point B.

Answer:

The set of all points in a plane that are equidistant from two points is a Perpendicular Bisector.

Step-by-step explanation:

Given: Two points on the plane.

We need to find  what has set of all such point which is equidistant from two given fixed point.

Point which is equidistant from two fixed point is known as mid point of the line segment formed by joining the fixed points.

So, all the point which is equidistant from fixed points form a perpendicular bisector.

Therefore, The set of all points in a plane that are equidistant from two points is a Perpendicular Bisector.

Answer:

The other two other representation are (6 , -4π/3) and (-6 , -π/3)

Step-by-step explanation:

* Lets revise some important facts about the polar form of a point

- In polar coordinates there is an infinite number of coordinates for a

 given point

- The point (r , θ) can be represented by any of the following coordinate

  pairs (r , θ+2πn) , (-r , θ + [2n+1]π) , where n is any integer

* Now lets solve the problem

∵ A point has polar coordinates (6 , 2π/3)

- We can find many points as the same with this point

- The point (r , θ) can be represented by any of the following coordinate

  pairs(r , θ + 2πn) and (-r , θ + (2n + 1)π), where n is any integer.

∵ The angle in [-2π , 2π]

∵ r = 6 and Ф = 2π/3

- Let n = -1

∴ (r , Ф + 2πn) = (6 , 2π/3 + 2π(-1)) = (6 , 2π/3 - 2π) = (6 , -4π/3)

* One point is (6 , -4π/3)

∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (2(-1) + 1)π) = (-6 , 2π/3 + (-2 + 1)π)

∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (-1)π) = (-6 , 2π/3 - π)

∴ (-r , θ + (2n + 1)π) = (-6 , -π/3)

* One point is (-6 , -π/3)

Final answer:

To find two additional polar representations of a point, you can add or subtract 2π radians (or 360° if using degrees) from the original angle, while keeping the radius the same.

Explanation:

A student has asked for two additional polar representations of a point. Polar coordinates specify the location of a point in a plane by a distance from the origin (r) and an angle (φ) with respect to the positive x-axis. To find additional representations, we can add 2π radians to the angle for each full rotation around the circle, keeping the same distance 'r'. For example, if a point has polar coordinates (r, φ), two other representations could be (r, φ + 2π) and (r, φ - 2π), or if in degrees, (r, φ + 360°) and (r, φ - 360°).

Answer:

[tex]\boxed{g(x) = (x - 6)(2x - 1)}[/tex]

Step-by-step explanation:

An x-intercept is the value of x when g(x) = 0. So, for each function, we must set g(x) = 0 and solve for x.

(a) g(x) = 2(x + 1)(x +  6) = 0

x + 1 = 0     x + 6 = 0

    x = -1           x = -6

Wrong.

(b) g(x) = (x - 6)(2x - 1)

x - 6 = 0     2x – 1 = 0

    x = 6            2x = 1

                          x = ½

Right.

(c) g(x) = 2(x - 2)(x - 6)

x - 2 = 0     x - 6 = 0

    x = 2           x = 6

Wrong.

(d) g(x) = (x + 6)(x + 2)

x + 6 = 0     x +2 = 0

    x = -6          x = -2

Wrong.

The only function that has x-intercepts at (½, 0) and (6, 0) is

68/4                       to get how many miles per gallon

17

51/17                       to see how many gallons of gas

3 gallons of gas

Based on the information given, Hank's pickup has a fuel efficiency of 17 miles per gallon. Therefore, it will require approximately 3 gallons of gas to travel 51 miles.

To determine how many gallons of gas Hank's pickup will need to travel 51 miles, we first establish the rate of gas consumption for the vehicle. As per the given data, Hank's pickup can travel 68 miles on 4 gallons. This gives us a rate of 68 miles/4 gallons = 17 miles per gallon.

Now, to find out how many gallons are required to travel 51 miles, we divide 51 miles by the rate of 17 miles per gallon. So, the calculation is as follows:

51 miles ÷ 17 miles/gallon = 3 gallons.

Therefore, Hank's pickup will require approximately 3 gallons to travel 51 miles.

#SPJ3

Answer:

43.75 inches or 43 and 3/4 inches.

Step-by-step explanation:

Ok, thanks for the complement of information.

So, to find the volume of that step, which is a rectangular prism, we would use the simple formula:

V = length *  width * height

In this case, we have the total volume (3,500 cu in), we have the width (10 inches)  and we have the height (8 inches).  But we need to find out the new length in order for him to use all 3,500 cu in of cement.

So, we transform the formula above into:

length = V / (width * height)

then we plug-in the numbers:

length = 3,500 / (8 x 10) = 3,500 / 80 = 43.75

So, the new length of the step would be 43.75 inches or 43 and 3/4 inches.

In your question, we are trying to find the total amount of money raised when the money is rounded to the nearest thousands.

In order to solve the problem, we would need to round the money raised to the thousands place.

The thousands place would be the number before the comma. (_),000.

Lets round for Part A:

89,351. The thousands place would be 9 in this case, when you look at the number to the right of it (3), it's not big enough to make 9 bigger, so we would keep the thousands place the same. It would end up as 89,000.

102,459. The thousands place would be 2, the number to the right of it is not big enough to be rounded up, so we would keep it the same. It would end up as 102,000.

78,505. The thousands place would be 8. The number to the right of it is a big enough number to let the number 8 be rounded, therefore we would round the 8 up to 9. It would end up as 79,000.

Part B

Our current values would be 89,000, 102,000, and 79,000.

Now, for part B, we would add the rounded values to get an estimate of the money saved:

[tex]89,000+102,000+79,000 =270,000[/tex]

You should get 270,000. Remember, that's just an estimate number.

Part C:

The answer choice that's close to that number is answer choice (3), $270,315.

Your FINAL answer should be (3) $270,315.

Do 19.32 x 40.26 which should equal $777.82
