Question

d

Answer 1

y varies directly as the square of x $$\Huge y=kx^2$$

Answer 2

Now use the given information: When x = 5, y = 5

to solve for k. Then find y when x = 10.

Answer 3

@Mercedes00312 are you still there?

Answer 4

What did you get for k?

Answer 5

5=25k ?

Answer 6

Yes, now solve for k.

Answer 7

i dont know howwww

Answer 8

use the idea of balance...whatever you do to one side of the equation you must do the same thing to the other

Answer 9

here divide both sides by 25 to get the k alone on one side

Answer 10

5/25 = k

Answer 11

Yes, now simplify please

Answer 12

1/5 = k

Answer 13

Correct, now what is the equation with this constant.

Answer 14

replace k with 1/5

Answer 15

1/5 * 25 = 5 which isnt an answer

Answer 16

Only k gets replaced in y = k x^2

Answer 17

$$\Huge y=\frac{1}{5}x^2$$

Answer 18

Now answer the question "Find y when x = 10" with this equation.
