Answer:
-3
Step-by-step explanation:
You replace the x in the equation for 5 so the problem to work it out would be f(x)=-2(5)+7
then you just solve the equation normally
Answer:
x = 5.25
y = 7.5
Step-by-step explanation:
Since line 1.5 is parallel to line x which is parallel to line y
then 2/(2+5) = 1.5/x
2x = 7(1.5)
2x = 10.5
x = 5.25
Similarly, 2/(2 + 5 + 3) = 1.5/y
2y = 10(1.5)
2y = 15
y = 7.5
Well I believe it's 33.333333%
