If f(x) = 5x – 2 and g(x) = 2x + 1, find (f + g)(x)

(f + g)(x) = 7x - 1

Step-by-step explanation:

Given :  f(x) = 5x – 2 and g(x) = 2x + 1

We have to find  (f + g)(x)

Consider  (f + g)(x) = f(x) + g(x)

Also, given  f(x) = 5x – 2 and g(x) = 2x + 1

Substitute, we have,

f(x) + g(x) = 5x - 2 + 2x + 1

LIKE TERMS are terms having same variable with same degree.

Simplify by adding like terms,  we have,

f(x) + g(x) = 5x + 2x - 2  + 1

f(x) + g(x) = 7x  - 1

Thus, (f + g)(x) = 7x - 1

Step-by-step explanation:

So you have 800 per month on rent and that 15%

given 100-15=85%

so how many times does 85 divide by 15?

85/15=5.66

so multiply that factor by 800 and add 800 to get the monthly budget.

Best!
