8x2+64x=0
16x+64x=0 ===> x=0
Answer:fr
Step-by-step explanation no cap
Y=mx+b
x=number of newspapers
37.5 earned for 5 newspapers
37.5=5m+b
earned 75 and deliverd 20 newpapers
75=20m+b
we have
37.5=5m+b and
75=20m+b
multiply first equaiton by -1 and add to other equaiton
-37.5=-5m-b
<u>75=20m+b +</u>
37.5=15m+0b
37.5=15m
divide both sides by 15
2.5=m
sub back to find b
75=2.5(20)+b
75=50+b
minsu 50 both sides
25=b
y=2.5x+25 is lnear funtion
1) 2x + y = 8 2) x - 3y = -3
y = -2x + 8 y = -x - 3 / -3
y-coordinate: (0, 8) x-coordinate: (-3, 0)
