Answer:
D
Step-by-step explanation:
--2x-2x-2x-2 = -16
2x (-2x-2x-2) = -16
-2x-2= 4
4x-2+8= 0
-16+-16+4+0 = -32+4
= -36
Answer:
p = -7
Step-by-step explanation:
-6p+7+21p=14+16p
Collect Like Terms.
15p+7=14+16p
Move Terms
15p-16p=14-7
Collect Like Terms Subtract
-p = 7
- change the signs
Both equal so set equal to each other
-1/3y+4/3=2y+6
times both sides by 3
-y+4=6y+18
add y to both sides and minus 18 both sides
-14=7y
divide both sides by 7
-2=y
sub back
x=2y+6
x=2(-2)+6
x=-4+6
x=2
(2,-2)
Answer:
4y+x-3=0
Step-by-step explanation:
The equation is y=mx+b
1) Use the coordinates from the first point
(-1,1)
1= -m+b
2) Use the coordinates frm the second point
(-5,2) (y=mx+b, use x=-5, y=2)
2=-5m+b
You have the system of equations
1=-m+b (multiply by -1) -1= m-b
2=-5m+b
Add the first equation (multiplied by -1) and the second one
-1+2= m-b-5m+b
1= -4m
m=-0.25
2=1.25+b
b=0.75
y=-0.25x+0.75
4y= -x+3
4y+x-3=0
