Answer:

(3/2, 6)

Step-by-step explanation:

y = 4x

8x + y = 18

this says y is 4x so you can replace y with 4x

8x + 4x = 18

12x = 18

/12 /12

x = 3/2

now sub x into y = 4(3/2)

y = 12/2

y = 6

Answer: C

Step-by-step explanation:

x = 2 $\sqrt{y+2}$ - 6

x + 6 = 2 $\sqrt{y+2}$

((x+6)/2 = $\sqrt{y+2}$ )^2

(x+6/2)^2 = y+2

y = (x+6/2)^2 -2

y= 1/4x^2 +3x +7
