Step-by-step explanation:
The equation of the line is y = 4x - 9.
Plug in 2 for x, and -4 for y
2(2)² + 3(2)(-4) - (-4)²
2² = 4(2) = 8
3(2) = 6(-4) = -24
-4² = 16
8 - 24 - 16 = answer
Simplify.
answer = 8 - 40
answer = -32
-32 is your answer
hope this helps
Answer:
yes what do you want help with
I see you accidentally pasted the expression 2(4x-3)+3x-1 twice, so
expand 2(4x-3) to get
2(4x)+2(-3)=8x-6
now we have
8x-6+3x-1
regrouping we get
8x+3x-6-1
adding like terms
11x-7
A is 11x-4, not 11x-7, wrong
B is wrong
C. hmm, 6x-6+5x-1=11x-7, yep
D is the same, we can see
C and D are correct
