Answer:
M=(9, 13.5)
Step-by-step explanation:
What you do is you need to use the midpoint formula.
(x_1+x_2/2), (y_1+y_2/2).
(11, 13) and (7, 14) are your points and you put those numbers into the equation.
11 and 7 are x and 13 and 14 are y.
(11+7/2), (13+14/2)
M=(9, 13.5) is your answer.
Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

Solve for x

Find the value of y
substitute the value of x in the equation A

so

therefore
The solution is the point (-2,-2)
Answer:
27
Step-by-step explanation:
X/39=(X+18)/65
65X=39X+702
26X=702
X=27
Answer:
Step-by-step explanation:
2(63+4x+3)=276
4x+66=138
4x=72
x=18
AD=BC
AD=4x+3, using x=18 found earlier
AD=4(18)+3
AD=72+3
AD=75
