3 0

Answer:

B) Graph B only.

Step-by-step explanation:

Table A is not correct, because:

In Y = 2X, replacing each row:
3 =/= 2 x 2
6 =/= 2 x 4
9 =/= 2 * 6

Table B is correct, because:
When Y is 2, X is 1 which is equal to 2x1.
When Y is 4, X is 2 which is equal to 2x2.

H. 2x – 7 = 3 squared

Lubov Fominskaja [6]

Answer:

h. x=8

Step-by-step explanation:

$2x-7=3^2$

Step 1) Square the 3

$2x-7=9$

2) Add 7 to both sides

$2x-7(+7)=9(+7)$

$2x=16$

3) Divide both sides by 2

$\frac{2x}{2} =\frac{16}{2}$

$x=8$
