In the diagram below segment DEF is shown (since all three letters are shown, they are collinear). If DE = 3x + 2, EF = x + 5, and DF = 23, algebraically find the value of x

Step-by-step explanation:

Given

As per segment addition postulate

Substituting values:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

according to egenuity the answer is

step-by-step explanation:
