Step-by-step explanation:
5x-6+7x+18=180
12x=180+6-18
12x=168
168÷12=14
X=14
for y
3y+11=7x+18(7×14+18)
3y+11=116
3y=116-11
3y=105
y= 35
Answer:
Input value/x = 9
Step-by-step explanation:
The output value means y and the input value means x.
So they've told us the output value y = 4.5
Sub this into the function they gave us to get x
y=x/2
4.5=x/2
9=x
Y=1/6x+3/2
You're going to use the point-slope formula to find the equation you're looking for.

Replace <span>x = 2 into f(x)=7x-5
</span> f(2)=7(2)-5 = 14 -5 = 9
answer is <span>A. 9</span>
