20 - 4x = 2(4 - 8x) This needs solving
Olenka [21]

20 - 4x = 2(4 - 8x)

Make sure to do the parentheses first or factor out first

20 - 4x = 8 - 16x

add 16x to both sides

20 + 12x = 8

Subtract 20

12x = -12

Divide by 8

x = -1

What is the primary difference between exponential and linear functions?
Yanka [14]

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as x^2, or 5x^2+7x, etc.

An exponential function wouldn't be x^2, it would be 2^x! Or 3^x, or (1.738283)^x, etc. Therefore, D is eliminated.

So, the answer is \boxed{A} and we're done!

Find the value of x (URGENT/GIVING BRAINLIEST)
natta225 [31]

Answer:

B)10

Step-by-step explanation:

Because this is a right angle(indicated by the red box) the total measure should be 90°.

And based on that we say 5X +40=90

Subtract 40 from both sides to get 5x=50

And then divide both sides by 5 to get x=10
