Point E is the midpoint if DF. If DE=8x-3 and EF = 3x + 7, what is x?

Since E is in the middle of D and F, then

DE= EF

8x -3 = 3x +7

8x -3x = 7 +3

5x = 10

x = 10/5

x = 2

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
