Answer:
30ft
Step-by-step explanation:
50- 20 = 30
hope it helps!
Y=mx+b
slope=m
yint=b
we are given
slope=-2/3
point=(-3,-1)
y=-2/3x+b
input point -3,-
x=-3
y=-1
find b
-1=-2/3(-3)+b
-1=2+b
minus 3
-3=b
y=-2/3x-3
answer is D
X+5y=4
2x+10y=8
x=<u>-5y+4
</u>2(-5y+4) +10y=8 substituted in the equation for x
-10y+8+10y=8 distributed
<u />8=8 combined like terms (-10y+10y)
0=0
