Answer:
ok so we have to make it so we can get rid of one of the varibles by adding or subtracting
so lets multiply the first one by 4
120x+16y=4160
minus the second one so
108x=2160
divide by 108
x=20
then we just plug in
12(20)+16y=2000
240+16y=2000
-240
16y=1760
divide by 16
y=110
(20,110)
Hope This Helps!!!
Answer:
0=0
Step-by-step explanation:
Add zero
0+2=2
2=2
Subtract 2 from both sides of the equation
2=2
2−2=2−2
Simplify
Combine like terms
2−2=2−2
0=2-2s
or
0=2s-2
0=0
Answer 0=0

Answer:
1/8
Step-by-step explanation:
P(-3, 0) and Y(5,-1)
If PLAY is reflected over x-axis, then P-->P'(-3,0) and Y-->Y'(5,1)
Slope of P'Y' = (1 - 0)/(5+3) = 1/8
