Substitute x for 7.
f(x)=22x+12
f(7)=22(7)+12
Multiply first, then complete addition.
f(7)=154+12
f(7)=166
Answer:
A or d
Step-by-step explanation:a or d
A or d
8(w-2)=2w+44
We move all terms to the left:
8(w-2)-(2w+44)=0
We multiply parentheses
8w-(2w+44)-16=0
We get rid of parentheses
8w-2w-44-16=0
We add all the numbers together, and all the variables
6w-60=0
We move all terms containing w to the left, all other terms to the right
6w=60
w=60/6
w=10
The value of x is a number :)
