Answer:
Step-by-step explanation:
To find the x intercepts, substitute in 0 for y and solve for x
So,
2x^2+2x-4 = 0
2(x^2+x-4) = 0
2/2(x^2+x-4) = 0/2
x^2+x-4 = 0
(x-1) (x+2) = 0
now,
x-1 = 0
x = 1
or
x+2 = 0
x = -2
The x intercepts for the parabola (1,0), (-2,0)
Answer:
C.
Step-by-step explanation:
C. best describes the situation:
$3.50 (per drink she buys) is subtracted from her $40 gift card.
—Example———————————
Let’s say Katie wants 2 drinks.
(x is the amount of drinks she wants.)
So in this case:
x = 2 (because she wants 2 drinks.)
Plug it into your equation.
3.50x - 40 —> 3.50(2) - 40
($3.50 times 2 is $7. Aka 2 drinks cost $7.)
$7 - $40
7 dollars is deducted from her 40 dollars.

While A describes:
$3.50 (per drink she buys) is added to her $40 gift card.
B describes:
$40 (per drink she buys) is subtracted from $3.50
D describes:
-$40 (per drink she buys) added to $3.50
E describes:
-$3.50 (per drink she buys) is added to her $40 gift card.
