Answer:
$1.45
Step-by-step explanation:
7.25 divided by the 5 packs
7.25/5= $1.45 a pack
The first one, 4x is the slope and the +3 is the y-intercept
Answer:
a and d = 32
Step-by-step explanation:
since ABC and DEF are similar m<A = m<D so you have the equation
5x + 12 = 8x
subtract 8x from both sides
5x + 12 -8x = 0
subtract 12 from both sides
5x -8x = -12
combine like terms
-3x = -12
devide by -3
x = 4
plug 4 into equation
5(4) + 12 = 8*4
20 + 12 = 32
32 = 32
The answer to this question will be C
Answer:
Step-by-step explanation:
a) y=![x^{2} -4x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-4x)
x=-1 ⇒ y=![(-1)^{2} +4=1+4=5](https://tex.z-dn.net/?f=%28-1%29%5E%7B2%7D%20%2B4%3D1%2B4%3D5)
x=1 ⇒ y=![1^{2} -4=1-4=-3](https://tex.z-dn.net/?f=1%5E%7B2%7D%20-4%3D1-4%3D-3)
x=2 ⇒ y=![2^{2} +8=4-8=-4](https://tex.z-dn.net/?f=2%5E%7B2%7D%20%2B8%3D4-8%3D-4)
x=4 ⇒ y=![4^{2} -16=16-16=0](https://tex.z-dn.net/?f=4%5E%7B2%7D%20-16%3D16-16%3D0)
b)
=![x^{2} -4x+4-4=(x-2)^{2}-4](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-4x%2B4-4%3D%28x-2%29%5E%7B2%7D-4)
so the blue one
