F(x)=-2x2+4x-6
f(0)=-2x2+4x0-6
f(0)=-4+0-6
f(0)=-10
The correct answer for the slope is 1/4
Convert the meter distance to KM so thaey are all the same measurement:
1 meter = 0.001 km
400 m x 0.001 m/km = 0.4 km
Now add all three distances:
Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.
The answer is B.
Ok so the solution which greenrune will (hopefully) correct
total is 1.5
p+r=1.5
rule is 1 more than pencil
r=1+p
sub 1+p for r
p+1+p=1.5
2p+1=1.5
minus 1 from both sides
2p=0.5
divide both sides by 2
p=0.25
pencil=$0.25
