This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
Answer:
y = -2(x + 3)² + 2
y = 2{ -(x + 3)²+ 1}
y = 2{ -(x² + 6x + 9) + 1}
y = 2{ -x² - 6x - 9 + 1}
y = 2{ -x² - 6x - 8 }
<u>y = -2 { x² + 6x + 8}</u>
OR
<u>y = -2{(x + 4)(x + 2)}</u>
C = cost on individual hat, "18 = 3c" would be the equation to describe how much each hat costs. Each hat would cost $6 each.
Answer:
x=9 and angle B=40
Step-by-step explanation:
5x-5=3x+13
Subtract -3 on both sides of x
5x(-3)-5=3x(-3)=+13
2x-5=13
Add 5 to both sides
2x-5(+5)=13(+5)
2x=18
Divide by 2
x=9
Now that you know x=9, plug it into 3x+13
So, 3(9)+13= 27+13= 40
so ya thats my answer hopefully it helps
(btw both angle A and B are the same so thats why u put them equal)
hope it really helps.....!!!!
