Step-by-step explanation:
Option A is the correct answer
f(x)=8x+2
put x=-4
then out =8(-4)+2 = -32+2= -30
Answer:
B
Step-by-step explanation:
There are 48 flavors and toppings. Since 16 are flavors, 32 are toppings. Dividing the 32 topping equally between 8 children is 4 toppings per child.
32 ÷ 8 = 4
Plug in (3,-1) into equations to see:
-1=2-3
-1=-1 CHECK
3-2(-1)=2(3)
3+2=6
5=6 NO
This is not a solution.
For this, you use the Law of Distribution and multiply -1 by all terms in the parentheses. 7 • -1 = -7; -c • -1 = c. Then you combine them, but since c is a variable, -7 + c is the most simplified it can get. I hope this helped!
The fastest way is to just use a scientific calculator.
To do it without a calculator, use prime factorization.
I'll only do the second one which is the answer.
27 x 8
= 3^3 x 2^3 = 6^3
Which is a perfect cube.
