Answer:
7. 
8. 
Step-by-step explanation:
We are given two function, f(x) and g(x).
We want to find their addition and their subtraction, and we do this combining like terms.
The functions are:
7. Find (f+9) (x)
So
8. Find (f - g) (x)
So
Let's say stress ball cost x and t shirt cost y
8x+5y=111.75
12x+4y=102.00→3x+y=25.5→y=25.5-3x
8x+5(25.5-3x)= 111.75
8x+127.5-15x=111.75
-7x=-15.75
x=2.25
12x+4y=102
12(2.25)+4y=102
27+4y=102
4y=75
y=18.75
d is the correct answer

Step-by-step explanation:
Each space between 2 lines represent 6 units. (from -6 to 0 is 6 units, from 0 to 6 is 6 units)
