The correct answer is A) adults tickets: 19
Answer:
- 2x² + 7x + 1
Step-by-step explanation:
f(x) - g(x)
= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1
= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms
= - 2x² + 7x + 1
27x + 9
------------
3
Break down the fraction. 3 is the common denominator, so it is the denominator of both numerators.
27x/3 + 9/3 = 0
9x + 3 = 0
9x = -3
x = -3/9 simplified to x = -1/3
Or simply multiply the fraction with 3/1 to remove the denominator, which is 3.
27x + 9 3 27x + 9
----------- x ------- = ----------------- or 27x + 9 = 0 ; look for x.
3 1 1
To check: Substitute x by its value:
(27x + 9) / 3 = 0 ⇒ ((27 * -1/3) + 9) / 3 = 0
⇒ (-9 + 9)/3 = 0 ⇒ 0/3 = 0 ⇒ 0 = 0
