8/21,13/21 because .16/42=x/100 and then cross multiply and simplify
The formula

means that from statement q implies statement p.
When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement

have a form: "If the graphs of two functions intersect at exactly one point, then two linear functions have different coefficients of x."
<h3>
Answer: y = 7</h3>
Work Shown:

Explanation:
I replaced every x with -1. Then used the order of operations (PEMDAS) to simplify. Keep in mind that
and not 
Plug in the 6 and -1 to get the answers
f(6)=120
f(-1)= 8
Answer:
15 and 12
Step-by-step explanation:
Set the two sides as x and y
y=x-3
P = 2w+2l
2x+2(x-3) = 54
4x-6=54
4x=60
x=15
y=12
