Answer:

b = -57/10

Step-by-step explanation:

Let's first distribute everything out:

-8(1 + 5b) = -8 * 1 + (-8) * 5b = -8 - 40b

2(86 - 1) = 2 * 85 = 170

So, we have:

-8 - 40b - 170 = 50

-40b - 178 = 50

-40b = 50 + 178 = 228

b = -228/40 = -57/10

Thus, the answer is b = -57/10.

Hope this helps!

HELP ME PLEASE!!<br> is y=2x^2 - 4 linear or non linear

OleMash [197]

Answer:

non-linear

Step-by-step explanation:

Linear functions can only have powers of 1 for the x and y terms and the terms must not be multiplied.

The function y =2x^2-4 has a power of 2 on the x so it is not linear. It is parabolic.
