Answer: 5, 3, $\dfrac{1}{6}$ , D

Step-by-step explanation:

-5 < 0 so f(-5) = | -5 | = 5

-3 < 0 so f(-3) = | -3 | = 3

6 > 0 so f(6) = $\dfrac{1}{6}$

graph D (since x can equal zero)

X + 5y - 10 = 0 x = 2y - 8

ipn [44]

So since we know what x is, we can substitute it into the original equation for x like so to solve for y...

(2y - 8) + 5y - 10 = 0
2y - 8 + 5y = 10
2y + 5y = 18
7y = 18
y = 18/7 (or about 2.57)

So now we know what x is, we can sub it into the below equation to solve for x...

x = 2(18/7) - 8
x = 36/14 - 8 (or about -5.43)
