the x value of point a is 5

The x value of point A is; 5

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line.

We have been given a graph representing the point A.

therefore, we need to find the coordinate of the given point.

So, we can see that the coorddinate of the point A is (5, 5)

The value x in the point A would be 5.

Step-by-step explanation:

(1/4)*x-(1/8) = (1/2)*x+7/8

First rearrange the numbers

(1/4)*x-((1/2)*x)-(1/8)-(7/8)

1/4*x ((-1/2)*x)-(1/8)-(7/8)

-1/4*x-1 = 0 + 1

Mary is 10 yrs old now.

Explanation:

10+20=30

30÷3=10

So, Mary has to be 10yrs old now.

Mary is currently 10 years old.

Given that in coming 20 years Mary's age will be 3 times her present age, we need to calculate her present age,

Let's assume Mary's current age is represented by "x". According to the given information, in 20 years, Mary will be three times as old as she is now. Therefore, her age in 20 years will be 3 times her current age, which can be expressed as 3x.

So, we can set up the equation:

x + 20 = 3x

To solve this equation, we can subtract x from both sides:

20 = 2x

Then, we can divide both sides by 2:

x = 10

Therefore, Mary is currently 10 years old.

Answer:

x = 8

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides, thus

x² + 6² = 10²

x² + 36 = 100 ( subtract 36 from both sides )

x² = 64 ( take the square root of both sides )

x = [tex]\sqrt{64}[/tex] = 8

Answer:

z = 24°

Step-by-step explanation:

The 3 angles 48, x and x form a straight angle and sum to 180°, thus

x + x + 48 = 180

2x + 48 = 180 ( subtract 48 from both sides )

2x = 132 ( divide both sides by 2 )

x = 66

The 3 angles in a triangle sum to 180°

sum the 2 known angles and subtract from 180

z = 180° - (66 + 90)° = 180° - 156° = 24°

By moving the decimal according to the number of places expressed by the exponents, we can see the real value of each answer choice.

A. .0008 lbs not a realistic weight for an 18-wheeler

B. 800 lbs closer but still not enough weight

C. .08 nope not this one either.

D. 80,000 lbs. this is probably in the range we are looking for.

If the exponent is negative, move the decimal that many spaces left. If the exponent is positive, move the decimal that many space right.

The correct answer is D.

Answer:

The reasonable estimate for the weight of an 18-wheeler is [tex]8 * 10^{4} lb[/tex]

Step-by-step explanation:

The average and legally maximum weight of an 18-wheeler is 80,000 pounds.

From option a through d, we check which of the measurement is close or equivalent to 80,000 pounds

By converting this, we have

[tex]= 8 * \frac{1}{10000} lb[/tex]

[tex]= \frac{8}{10000} lb[/tex]

[tex]= 0.0008 lb[/tex]

By converting this, we have

[tex]= 8 * 100 lb[/tex]

[tex]= 800 lb[/tex]

By converting this, we have

[tex]= 8 * \frac{1}{100} lb[/tex]

[tex]= \frac{8}{100} lb[/tex]

[tex]= 0.08 lb[/tex]

By converting this, we have

[tex]= 8 * {10000} lb[/tex]

[tex]= {80000} lb[/tex]

From the 4 conversions, only  [tex]8 * 10^{4} lb[/tex] is equivalent to the average and legally maximum weight of an 18-wheeler, 80,000 pounds.

Hence, the reasonable estimate for the weight of an 18-wheeler is [tex]8 * 10^{4} lb[/tex]

Final answer:

0.64 is a finite decimal with zero repeating digits as it does not have digits that continue infinitely after the decimal.

Explanation:

The number 0.64 is a decimal that has two digits after the decimal point. These digits (6 and 4) do not repeat infinitely, making them non-repeating decimal digits. Therefore, there are zero repeating digits in 0.64. A repeating decimal would have one or more digits after the decimal point that continue infinitely, often denoted by a bar over the repeating digits. Since 0.64 does not exhibit this pattern, it is a finite decimal.

Answer:

C

Step-by-step explanation:

The shape consists of a cylinder and a hemisphere.

The volume of a cylinder is:

V = πr²h

where r is the radius (half the diameter) and h is the height.

The volume of a hemisphere is:

V = ⅔ πr³

where r is the radius (half the diameter).

The cylinder and hemisphere both have a diameter of 8 cm, or a radius of 4 cm.  The cylinder has a height of 17 cm.

So the total volume is:

V = π(4 cm)²(17 cm) + ⅔ π(4 cm)³

V = π (272 + 128/3) cm³

V ≈ 988.6 cm³

For this case we must find an expression equivalent to:

[tex]log_ {5} (\frac {x} {4}) ^ 2[/tex]

So:

We expanded [tex]log_ {5} ((\frac {x} {4}) ^ 2)[/tex]by moving 2 out of the logarithm:

[tex]2log_ {5} (\frac {x} {4})[/tex]

By definition of logarithm properties we have to:

The logarithm of a product is equal to the sum of the logarithms of each factor:

[tex]log (xy) = log (x) + log (y)[/tex]

The logarithm of a division is equal to the difference of logarithms of the numerator and denominator.

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

Then, rewriting the expression:

[tex]2 (log_ {5} (x) -log_ {5} (4))[/tex]

We apply distributive property:

[tex]2log_ {5} (x) -2log_ {5} (4)[/tex]

I hope to understood my writing

To determine at what time the two lorries will meet, we can use the concept of relative speed. Since the lorries are moving towards each other, their relative speed is the sum of their individual speeds.
The speed of the first lorry is 63 km/h and the speed of the second lorry is 67 km/h. Together their combined speed is:
63 km/h + 67 km/h = 130 km/h
Now we need to calculate how long it will take for them to cover the distance of 520 km between the two towns at their combined speed.
The time taken to cover a distance is equal to the distance divided by the speed, so the time taken \( t \) in hours can be found by:
\( t = \frac{distance}{speed} \)
Substituting the known values into this formula gives us:
\( t = \frac{520 km}{130 km/h} = 4 \) hours
Now we know the lorries will meet after 4 hours of travel.
Given that the lorries start to travel at 7:30 am, we add 4 hours to that time to find the meeting time.
7:30 am + 4 hours = 11:30 am
Therefore, the two lorries will meet at 11:30 am.

Let y we the number of hours battery will last.

So, 1/9 y = 3/5

y = 27/5

y = 5 + 2/5 hours

y = 5 hrs and 24 mins

Marta's jump rope is 75 inches long

Step-by-step explanation:

Hello!! This is how you solve it:

x + ( x - 10 x 3 ) = 120

2x - 10 x 3 = 120

2x - 30 = 120

+ 30. + 30

2x = 150

--- ------

2. 2

x = 75

Final answer:

Marta's jump rope is 87.5 inches long. This was determined by setting up an equation based on the information that Marta's rope is 10 inches shorter than three times Dilbert's rope length, and together they measure 120 inches.

Explanation:

The question involves finding the length of Marta's jump rope when it is known to be 10 inches shorter than three times the length of Dilbert's rope, and when both ropes laid end-to-end measure 120 inches long. Let's denote the length of Dilbert's jump rope as D inches. Therefore, the length of Marta's jump rope can be expressed as 3D - 10 inches. Since the combined length of both ropes is 120 inches, we can write the equation: D + (3D - 10) = 120.

Combining like terms, we get 4D - 10 = 120. Adding 10 to both sides gives 4D = 130, and dividing both sides by 4 yields D = 32.5 inches. Thus, Dilbert's rope is 32.5 inches long, and Marta's rope, being 3(32.5) - 10, calculates to 87.5 inches long.

Answer:

3y² + 7y + 4 = (3x + 4)(x + 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

∵ 3y² + 7y + 4

∵ ax² + bx + c

∴ a = 3 , b = 7 , c = 4

∵ a = h × k

∵ 3 = 3 × 1

∴ h = 3  , k = 1

∵ c = r × s

∵ 4 = 4 × 1

∴ r = 4 , s = 1

∵ c is positive

∴ hs + rk = b

∴ 3(1) + 4(1) = 7 ⇒ same value of b

∴ 3y² + 7y + 4 = (3x + 4)(x + 1)

Answer:

The factors of 3y^2 + 7y + 4 are

(y +1) and (3y + 4)

Step-by-step explanation:

It is given a quadratic equation in variable y

3y^2 + 7y + 4

To find the factors using splitting method

3y^2 + 7y + 4 can be written as,

 = 3y(y + 1) + 4(y + 1)

 = (y + 1)(3y + 4)

Therefore the factors of 3y^2 + 7y + 4 are

(y +1) and (3y + 4)

Answer: The number is 8

Step-by-step explanation:

 Let be "x" the certain number. Then "3 times a certain number" means that the number "x" is multiplied by 3. This is:

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

Now, "3 times a certain number is increased by 4" means that the we must add 4 to [tex]3x[/tex], in other words, this indicate an addition:

 [tex]3x+4[/tex]

And finally "3 times a certain number is increased by 4 the result is 28" means that  [tex]3x+4[/tex] is equal to 28. Then the expression is:

 [tex]3x+4=28[/tex]

To find the number "x", subtract 4 from both sides of the equation:

[tex]3x+4-4=28-4[/tex]

[tex]3x=24[/tex]

Dividing both sides of the equation by 3, you get that the number is:

[tex]\frac{3x}{3}=\frac{24}{3}\\\\x=8[/tex]

Answer:

Measure B= 121

Measure C=59

Step-by-step explanation:

10x-19=7x+23

3x=42

x=14

plug in x to the problem and you'll find Measure B is 121 so to find Measure C you'll have to subtract 180 and 121 to get 59.

The value of angle B is 121 degree and Angle C is 59 degree, and Angle D has the same measure as the angle B

It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides. It has one pair of opposite congruent angles.

We have a quadrilateral in which angle B and angle D are given.

As we know the opposite angles in the quadrilateral are same in measure.

10x - 19 = 7x + 23

3x = 42

x = 14

Angle B =  10x - 19 = 10(14) - 19 = 121 degree

Angle C =  7x + 23 = 7(14) + 23 = 121 degree

Angle A + Angle C = 360 - 121 -121 = 118

Angle C = 118/2 = 59

Thus, the value of angle B is 121 degree and Angle C is 59 degree, and Angle D has the same measure as the angle B
