Answer:
(f + g)(x) = – 3x^2 + 5x - 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= 5x^2 + 9x – 4 + (– 8x^2 – 3x – 4)
= 5x^2 + 9x – 4 – 8x^2 – 3x – 4
Combine
= – 3x^2 + 5x - 8
Given:
Salary = $400 a month
Rate of commission = 10%
Total sales = $2000
To find:
The total money you will make this month.
Solution:
We have,
Rate of commission = 10%
Total sales = $2000
Commission = 
= 
We know that,
Total money = Salary + Commission
= 
= 
Therefore, the total money you will make this month is $600.
Your answer is 16.2 I believe
x/6+4= 15
Subtract 4 from both sides; 4s cancel each other out
x/6+4-4= 15-4
x/6= 11
multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)
(x/6)(6)= (11)(6)
x= 66
ANSWER: x= 66
Hope this helps! :)
