Answer:
(f + g)(- 2) = 1
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) , thus
f(x) + g(x)
= x - 3 + x² - x
= x² - 3
Thus
(f + g)(- 2) = (- 2)² - 3 = 4 - 3 = 1
Simplifying
2x + 3y = 60
Solving
2x + 3y = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
2x + 3y + -3y = 60 + -3y
Combine like terms: 3y + -3y = 0
2x + 0 = 60 + -3y
2x = 60 + -3y
Divide each side by '2'.
x = 30 + -1.5y
Simplifying
x = 30 + -1.5y
Hope this helps! :D
