Midpoint of (a,b,c) and (e,f,g) is
((a+e)/2,(b+f)/2,(c+g)/2)
just average them
the x value
(2+-2)/2=0/2=0
the y value
(-2+0)/2=-2/2=-1
the z value
(4+6)/2=10/2=5
(0,-1,5) is da midopint

Answer:
Step-by-step explanation:
Let's solve for b.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx/−2x=6/−2x
b=−3x
Answer:
b=−3x
———————————————————
Let's solve for x.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2b.
−2bx/−2b=6/−2b
x=−3b
Answer:
x=−3b

Answer: x = 4
y = - 3
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x-3y = 13 ------------------------1
2x+4y=-4--------------------------2
We would apply the method of substitution in solving the equations. From equation 1, we would make x to stand alone by adding 3y to the left hand side and the right hand side of the equation. It becomes
x - 3y + 3y = 13 + 3y
x = 13 + 3y
Substituting x = 13 + 3y into equation 2, it becomes
2(13 + 3y) + 4y = - 4
26 + 6y + 4y = - 4
26 + 10y = - 4
Subtracting 26 from the left hand side and the right hand side of the equation, it becomes
26 - 26 + 10y = - 4 - 26
10y = - 30
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10y/10 = - 30/10
y = - 3
Substituting y = - 3 into x = 13 + 3y, it becomes
x = 13 + 3 × - 3
x = 13 - 9
x = 4
