Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16
Answer:
(1/5)x-5.4=y
Step-by-step explanation:
mx+b=y
m=(1/5)
(-8,-7)=(x,y)
(1/5)(-8)+b=(-7)
-1.6+b=-7
b=-5.4
(1/5)x-5.4=y

Answer:
The amount of money Skylar has now is $32
Step-by-step explanation:
Here in this question, we want to find the amount of money Skylar has presently.
Let the amount of money he has presently be $x
Now by doubling this amount, he will have enough money to buy the video game and still be left with a balance of $8
So let’s double the amount of money he has;
$x * 2 = $2x
let’s subtract the amount for the video game so he would be left with the $8
Mathematically;
2x -8 = 56
Collect like terms
2x = 56 + 8
2x = 64
Divide both sides by 2
2x/2 = 64/2
x = 32
