Factor the following expression completely.

9y^4 - 4x^6

Answer:

12

Step-by-step explanation:

0.8 is equal to 80%

you need to figure out 80% of 15

100% = 15

10% = 1.5

(x8)

80% = 12

you would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one

Answer:

Sample answer: The number of squares that are shaded divided by 15 must equal 0.8, so the number of squares must be 0.8(15), which equals 12. The fraction 12/15 reduces to 4/5 which is equal to 8/10.

Step-by-step explanation:

The sample answer on edge

292 days

Solution:

Step 1: Given data:

Principal = $2500

Annual rate = 9.3%

Simple interest paid = $186

Step 2: To find the number of year for the loan paid.

Simple interest = [tex]\frac{Principal\times rate\times year}{100}[/tex]

[tex]186=\frac{2500\times9.3\times years}{100}[/tex]

Do cross multiplication.

⇒ 186 × 100 = 2500 × 9.3 × years

⇒ [tex]\frac{186\times100}{2500\times9.3}=years[/tex]

⇒ [tex]years=\frac{4}{5}[/tex]

Step 3: To find how long the loan was paid in days:

1 year = 365 days

Multiply years by 365

⇒ [tex]days=\frac{4}{5}\times365[/tex]

⇒ days = 292

Hence, the loan was paid in 292 days.

Answer:

b=4

Step-by-step explanation:

6b+2=2b+18 add and subtract like terms

-2b. -2b

4b+2=18

-2. -2

4b=16

----- ----- divide

4. 4

b= 4

Answer: b = +4

Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side by subtracting 2b from both sides of the equation. That gives us 4b + 2 = 18.

Now we can move our numbers to the right by subtracting 2 from both sides and we get 4b = 16.

Divide both sides by 4 and b = +4.

To simplify this improper fraction we can turn it into a mixed number. The fact that the denominator is 2 and the numerator isn't divisible by 2 shows that it can't simplified any further as a improper fraction.

The radius of circle is 12 inches

Solution:

Given that,

Consider circle c with angle [tex]\frac{3 \pi }{4} \text{ radians }[/tex]

Minor arc AB measures [tex]9 \pi[/tex] inches

Therefore, we can say,

[tex]Central\ angle\ in\ radians = \frac{3 \pi }{4}\\\\Arc\ length = 9 \pi[/tex]

To find: Radius of circle

The length of arc when angle given in radians is:

[tex]s = r \times \theta[/tex]

Where,

"s" is the arc length and "r" is the radius and [tex]\theta[/tex] is the central angle in radians

[tex]9 \pi = r \times \frac{3 \pi }{4}\\\\r = 9 \times \frac{4}{3}\\\\r = 12[/tex]

Thus the radius of circle is 12 inches

y = 5x - 10 and y = 5(x + 2) are the system of equations that has no solution.

Step-by-step explanation:

The slope-intercept form of a straight line equation is given by, y = mx + c, where m is the slope and c is the y-intercept.

Now, only a system of parallel straight lines has no solution.

And the parallel straight lines have an equal slope and different y-intercept.

Hence, the given equation, y = 5x - 10 has slope equals to 5 and y-intercept - 10.

And the lines given in the options, only the second line i.e. y = 5(x + 2) has the same slope i.e. 5 and different y-intercept i.e. 10 ≠ - 10.

So, y = 5x - 10 and y = 5(x + 2) are the system of equations that has no solution. (Answer)

Both equations are correct because the veterinarian recommended that the weight the dog should have is 31 pounds. Another equation that represent the situation is:

31 = x

Step-by-step explanation:

Let's analyze the equation written by Mikala:

Answer: [tex]-31\ \°F[/tex]

Step-by-step explanation:

Degrees Celsius and Degrees Fahrenheit are defined as units of measurement of temperature.

In order to make the conversion from Degrees Celsius to Degrees Fahrenheit, you need to follow these steps:

Step 1: You must multiply the temperature in degrees Celsius by [tex]\frac{9}{5}[/tex] (or you can multiply it by 1.8).

Step 2: Then you must add 32 to the product obtained.

In this case, according to the information given in the exercise, you know that the reading at an Arctic research station showed that the temperature was [tex]-35\°C[/tex]

Therefore, applying the steps indicated before, you get that that temperature in degrees Fahrenheit is:

[tex]T_{(\°F)}=(-35)(\frac{9}{5})+32\\\\T_{(\°F)}=-31\ \°F[/tex]

A) No, the probability of getting a 3 on a fair die does not change. It will always be 1/6  no matter what she got on the previous roll.

Step-by-step explanation:

Lets define probability first

"Probability is the likeliness of occurrence of an event"

When we call a die fair, that means that each number on the die has an equal chance of occurrence when rolled.

If on 7 rolls, the outcomes were 7 each time, this doesn't mean that the chances of rolling a specific number on a fair die is changed. On the next roll, 3 will have the same probability as before that is 1/6

So,

The correct answer is:

A) No, the probability of getting a 3 on a fair die does not change. It will always be 1/6  no matter what she got on the previous roll.

Answer:

To solve this equation your goal is to get x by itself

First we need to distribute the 3 through the (2x-7)

x-6x+21=76 (-3*2x=-6x, -7*-3=21)

Your next step is to combine like terms

-5x+21=76 (x-6x=-5x)

Next subtract 21 from both sides

-5x=55 (21-21=0, 76-21=55)

Last you need to divide both sides by -5

x=-11 (-5/-5=1, 55/-5=-11)

x=-11

Hope this helps ;)

The solution to the given equation x - 3(2x - 7) = 76 is x = -11.

The equation is given as follows:

x - 3(2x - 7) = 76

First, distribute the 3 to the terms inside the parentheses:

x - 6x + 21 = 76

Combine like terms:

-5x + 21 = 76

Subtract 21 from both sides:

-5x = 76 - 21

-5x = 55

Divide both sides by -5 to solve for x:

x = 55 / -5

x = -11

Therefore, the solution to the given equation x - 3(2x - 7) = 76 is x = -11.

The equation of the required line in the slope-intercept form is

y = -3x + 10

Step-by-step explanation:

i) the required line passes through the point (5, -5)

ii) the required line is also parallel to the line 3x + y = -2 ⇒ y = -3x - 2

  Therefore the slope of the given line is -3.

  Therefore the slope of the required line is also -3

  The equation of the required line in the slope-intercept form is

  y - (-5) = -3(x - 5) ⇒ y + 5 = -3x + 15    ⇒      y = -3x + 10   ∴ 3x + y = 10.

Answer:

y + 3 = (-5/2)(x - 2)

Step-by-step explanation:

First look at y =5x + 2.  It's immediately apparent that the y-intercept is 2, or (0, 2).  (0, 2) must then be a point on the new line, and we are told that (2, -3) is also on this new line.

The general point-slope equation is y - k = m(x - h).

We need to determine the slope of the new line.

Let h = 2, k = -3, x = 0 and y = 2.  Then:

2 + 3 = m(0 - 2).  Therefore, -2m = 5, and m = -5/2.

Then the equation of the new line, in point-slope form, is

y + 3 = (-5/2)(x - 2)

Let's check this result.  Do the coordinates of the y-intercept, (0, 2) satisfy this equation?

Is 2 + 3 = (-5/2)(0 - 2) true?

Is 5       = (-5/2)(-2) true?  YES

The equation of line is 2y = -5x+ 4.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows

m = Δy/Δx

where, m is the slope

In the coordinate plane, it describes the slope of the line.

Given:

passes through the point (2,-3) and has the same y intercept as y =5×+2

The, the intercept for the required line is 2.

Now, using y= mx+b

-3 = m(2) + 2

2m = -5

m= -5/2

Now, the equation of line passes through (2, -3)

y - y1 = m(x- x1)

y + 3= -5/2( x-2)

2y + 6= -5x+ 10

2y = -5x+ 4

Hence, the equation of line is 2y = -5x+ 4.
