![x \leq -2\\ (- \alpha ,-2]](https://tex.z-dn.net/?f=x%20%20%5Cleq%20-2%5C%5C%0A%28-%20%5Calpha%20%2C-2%5D%20)
Note: the infinity character would not render correctly, so I used alpha instead. Pretend it's an infinity sign.
Answer:
Step-by-step explanation:
(-1, 1) (1, -3)
(-3 - 1)/(1 + 1)= -4/2 = -2
y - 1 = -2(x + 1)
y - 1 = -2x - 2
y = -2x - 1
answer is A
(y^2)^5 × y^8
Use the rule:

To get:
y^10, then, use the rule:

To eventually get:
y^(10+8) = y^18 or: y18 seeing as you wrote it like that.
Answer:
9 and 14
Step-by-step explanation:
One number is 5 less than a second number.
a = b - 5
:
Twice the second number is 8 less than 4 times the first.
2b = 4a - 8
replace a with (b-5)
2b = 4(b-5) - 8
2b = 4b - 20 - 8
2b - 4b = -28
-2b = -28
b = 14
then
a = 9
