Answer: B, D, and E
<u>Step-by-step explanation:</u>
f(x) = x² - 1
(0, 1): 1 = (0)² - 1 ⇒ 1 = -1 FALSE
(1, 0): 0 = (1)² - 1 ⇒ 0 = 0 TRUE
(3, 5): 5 = (3)² - 1 ⇒ 5 = 8 FALSE
(5, 24): 24 = (5)² - 1 ⇒ 24 = 24 TRUE
(-2, 3): 3 = (-2)² - 1 ⇒ 3 = 3 TRUE
(-4, -17): -17 = (-4)² - 1 ⇒ -17 = 15 FALSE
Explanation: The 4th one is the distributive property because it shows an equal sign and the 5th one is the inverse property of addition because it uses more than addition.
Answer: 4th one is distributive property 5th one is inverse property of addition
P.S. I am sure 95% sure that I am correct.
Answer:
x = 8
Step-by-step explanation:
6(x-8)= x- (8)
6x - 48=x - 8
6x- 48 + 48 = x - 8 + 48
6x = x + 40
6x - x = x + 40 - x
5x = 40
5x/5 = 40/5
x = 8
Hope it helps! :)
Answer:
$175
Step-by-step explanation:
let the original price be x
if 1/5 is off the price then the sells is at 4/5
4/5 of x = 140
thus,
4/5* x=140
4x = 140*5
x=700/4
x=$175
