Step-by-step explanation:
Your choice is correct, this is A
y-intercept is the coordinate of the point at which discount is zero and amount spent is $7.5
X^2+20=4
Subtract 20 from both sides.
x2+20−20=4−20
x2=−16
Take square root.
x=±√−16
Answer
No real solutions.
1/3(12x-24)=16
*3 *3
12x-24=48
+24 +24
12x=72
/12 /12
x=6
