The formula of a slope:

We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:

**Answer:**

D. -17/2

**Step-by-step explanation:**

1/2 - 4 (1/2 + 1)^2

First we evaluate what is inside the parentheses

1/2 - 4 (3/2) ^2

Now we square what is inside the parentheses

1/2 - 4(9/4)

Now multiply

1/2 -9

Get a common denominator 9 = 9 *2/2 = 18/2

1/2 - 18/2

-17/2

To solve this problem, we are going to use the percent proportion, a/b = p/100, where a is the part of a number b, the whole, and p is the percentage out of 100.

When we fill in our known integers into this equation, we get

21.12 / b = 25.6 / 100

Next, to simplify this equation, we should use cross products (means - extremes products theorem). This means multiplying the numerator of one fraction and the denominator of the other fraction and setting them equal to one another.

21.12(100)=25.6(b)

When we multiply, you get

2112 = 25.6b

Finally, we divide both sides by 25.6, to get our variable b, alone, and without a coefficient.

82.5 = b

Therefore, 25.6% **of the number 82.5 **is 21.12.

**Answer:**

It will take 11 minutes

**Step-by-step explanation:**

660 ÷ 60 = 11

Distance= rate×time

D=rt

660 (distance)= 60 (feet per minute or rate) × t (we have to find out the time it takes to get there.

We divide 660 by 60 to find the missing value, which is 11.
