Answer:
Step-by-step explanation:
Given

Solving (a): g(-1)
We make use of:
Because: 
is true for x =-1
Hence:
Solving (b): g(0.75)
We make use of:
Because: 
is true for x =0.75
Hence:
Solving (b): g(1)
We make use of:
Because: 
is true for x =1
Hence:
Well using elimination is easy because they basically did it for you.
4x-5y=-6
2x+5y=12
The postive 5y and negative 5y cancel out because -5y plus 5y is zero.
so you are left with
4x=-6
2x=12
Add these together
6x=18
divide both sides by 6 and Solve to find your x
x=3
Now we have to eliminate x to find y.
we multiply the second equation by -2 so it can cancel out so
(2x+5y=12)-2
-4x-10y=24
Add the equations together
4x-5y=-6
-4x-10y=24
You are left with -15y = 30
Solve for y
y = -2
So your final answer for the elimination would be
(3,-2)

Step-by-step explanation:
15% = 15/100 = .15
250 x .15 = 37.5
Answer:
Yes it is
Step-by-step explanation:
Each x value is represented by exactly one y value.
