How can percents describe a change in area?

1 answer:

7 0

Divide the change by the initial number to get a fraction and multiply by 100% to get a percent. The percent you get will describe the change in area in the mathematical language of numbers.

If d(x) = x2 - 7x - 7, find d(x - 1).

satela [25.4K]

Answer: x^2-9x+1

Step-by-step explanation:

x^2-7x-7 d(x-1)

(you would just replace x to (x-1)

(x-1)^2-7(x-1)-7

(solve by square rooting (x-1)(x-1) then foil)

x^2-9x+1

3v+4(v-2)= -29 solve for v

Lesechka [4]

Answer:

v = -3

Step-by-step explanation:

1) Expand.

3v + 4v - 8 = -29

2) Simplify 3v + 4v - 8 to 7v - 8.

7v - 8 = -29

3) Add 8 to both sides.

7v = -29 + 8

4) Simplify -29 + 8 to -21.

7v = -21

5) Divide both sides by 7.

v = -21/7

6) Simplify 21/7 to 3.

v = -3

PLEASE HELP ME D: given the parent function of f(x) = x3, what change will occur when the function is changed to f(x − 3)

Alexxandr [17]

Hello,

Your answer would be:

The parent function is : f ( x ) = x³
f ( x + 3 ) = ( x + 3 )³
shift to the left 3 units.

Plz mark me brainliest!

Hope this helps!
