Answer:
42
Step-by-step explanation:
Substitute 9 in for m, and 6 in for n
n+4m
6+4(9)
Multiply
6+36
Add
42
$27.64×3 =82.92
answer=$82.92
Answer: x = 4, y = 3
<u>Step-by-step explanation:</u>
and 
Using substitution method we get:

Any line can be expresses as:
y=mx+b where m=slope=(y2-y1)/(x2-x1) and b=y-intercept (value of y when x=0)
First find the slope:
m=(2-0)/(8-0)=2/8=1/4 so we have thus far:
y=0.25x+b, we solve for b using any point on the line, (8,2)
2=0.25(8)+b
2=2+b
0=b
So the line is:
y=.25x which they might also express as y=x/4
The answer is E. (1/4)x
I believe the correct answer is: B. But I’m not sure.
