Answer:
3m^4
Step-by-step explanation:
the third one
When there is a midpoint in a line segment, the two segments that are then produced have to be equal. So that means that because E is a midpoint of DF, DE=EF.
Set up the equation.
DE=EF
2x+4=3x+1
Then solve for x.
x=3
Then plug it back in the equation to find DE and EF.
DE=2x+4=2(3)+4=10
Because DE=EF then EF is also 10.
DF is made from the addition of DE and EF so DF is twice EF.
DF= 20
DE= 10, EF= 10, DF= 20

standard form: 10x - y = 0
Use the slope-intercept form to find the slope and y-intercept.
Slope: 10
y-intercept: (0, 0)
