Answer:
H.(4, -2) and (-5, 10)
Step-by-step explanation:
We have pairs of point (x,y)
If y decreases as x increases, we have an inverse variation.
In this question:
F.
y increases by 1 when x increases by 2. So not inverse.
G
x increases by 8 when x inches by 2. So not inverse.
H
x goes from -5 to 4, y decreases from 10 to -2. So inverse and H is the answer.
J.
x goes grom -3 to 2, y from -4 to 6, both increase, so this is not the answer.
1 pt= 437.1765 mL
0.5 pt= 0.5x437.1765= 218.58825 mL
Ratio = 218.58825/750= 0.2915 % =29.15%
Answer:
n = 0, n =2
Step-by-step explanation:
Given
(n + 1) + 3(n - 1) = 2(n - 1)(n + 1) ← distribute parenthesis on both sides
n + 1 + 3n - 3 = 2(n² - 1), that is
4n - 2 = 2n² - 2 ( subtract 4n - 2 from both sides )
0 = 2n² - 4n ← factor out 2n from each term )
0 = 2n(n - 2)
Equate each factor to zero and solve for n
2n = 0 ⇒ n = 0
n - 2 = 0 ⇒ n = 2
