Step-by-step explanation:
<u>Step 1: Define</u>
-2/5x - 2 = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 2 on both sides: -2/5x = 20
- [Division Property of Equality] Divide -2/5 on both sides: x = -50
Answer: n = 1, n = -1/3
<u>Step-by-step explanation:</u>
(3n - 1)² = 12n + 8
9n² - 6n + 1 = 12n + 8
9n² - 18n - 7 = 0
Substitute -18n with 3n - 21n and find the common factor of each side:
9n² + 3n -21n - 7 = 0
3n(<u>3n + 1</u>) -3(<u>3n + 1</u>) = 0
(3n - 3) (3n + 1) = 0
Solve for each factor:
3n - 3 = 0 3n + 1 = 0
3n = 3 3n = -1
n = 1 n = -1/3
Try to be more clear with this question. but, if I understood it correctly, g(x) would be the '' equation'' for a FUNCTION.
Hope it helps!!
