Answer:
(x - 24)(x - 4)
Step-by-step explanation:
Given
x² - 28x + 96
Consider the factors of the constant term (+ 96) which sum to give the coefficient of the x- term (- 28)
The factors are - 24 and - 4, since
- 24 × - 4 = + 96 and - 24 - 4 = - 28, thus
x² - 28x + 96 = (x - 24)(x - 4)
Step-by-step explanation:
I cant show a number line so i'll do my best to explain how its graphed.
15) x - 1 < 15
add 1 to both sides:
x < 16
Because it is less than, rather than less than or equal to, it's graphed with an open circle (not filled in) on 16, and everything less than 16 highlighted
---------------------------------------------------------
16) 2(y + 1) - 2 ≥ 12
distribute the 2:
2y + 2 - 2 ≥ 12
combine like terms
2y ≥ 12
isolate y:
y ≥ 6
This one is greater than or equal to, so it's graphed with a closed circle (filled in) and everything above 6 highlighted
9 * x = 9x
9 * 5 = 45
9 * 8y = 40y
9x + 45 + 40y
9x + 40y + 45
Answer:
Except 4 out of 6
the answer is the third one
