just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
Answer:
Simon takes approximately 13.76 hours to complete the job alone.
Step-by-step explanation:
We are given the following in the question:
Kamila can do a job in 26 hours
So, part of work done by Kamila in 1 hour =

Simon and Kamila working together can do the same job in 9 hours
.
So, (Simon and Kamila)'s 1 hour work =

So, Simon's 1 hour work =

So,
Simon can do
part of work in hour = 1
Time taken by Simon to complete the job alone =

Thus, Simon takes approximately 13.76 hours to complete the job alone.
2((x+2)(x+2)}-4=28
2{x^2 + 4x + 4}-4=28
2x^2 +4x=28
2(x^2+2x)=28
x^2+2x=28/2
x^2+2x=14
the answer is D. y≤ -2x + 2
take x=2
then (-2 x 2) + 2
⇒ -4 + 2 = -2
Step-by-step explanation:
(2m + 4) / 8 = w
2m + 4 = 8w
2m = 8w - 4
m = 4w - 2
