Answer:
X = 1
Step-by-step explanation:
1) Move the 3x to the left hand side and change its sign:
4x-19+3x=-12
2) Move 19 to the right hand side and change its sign:
4x+3x=-12+19
3) collect the like terms:
4x+3x= 7x
-12+19= 7
4) Divide both sides by 7
X = 1
Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) =3x - 8 and g(x) = x² + 4
- f(g(- 2)) = ?
<u>First find g(- 2):</u>
- g(- 2) = (-2)² + 4 = 4 + 4 = 8
<u>Find f(8):</u>
- f(8) = 3*8 - 8 = 24 - 8 = 16
Answer:
-6
Step-by-step explanation:
3n = n² - 54
n² - 3n - 54 = 0
n² - 9n + 6n - 54 = 0
n(n - 9) + 6(n - 9) = 0
(n - 9)(n + 6) = 0
n = 9 , -6
