Mathematics

Papessa [141]3 years ago

Answer:

20

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x

Substitute x = 2 into f(x) + g(x)

(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20

HELP PLSSS<br><br>solve the inequality -9x/11-7&lt;-5
Flauer [41]

Answer:

x < -22/9

Step-by-step explanation:

(-9x/11) - 7 < -5  (add 7 to both sides)

(-9x/11) < -5 + 7

-9x/11 < 2   (multiply both sides by 11)

-9x < 2(11)

-9x < 22   (divide both sides by -9)

x < -22/9  (answer)

edit: typos galore!
