Okay, so we will be using the formula y1-y2/x1-x2:
7--8/3-3=15/0
Now, we can't divide by zero so we can just say the slope of the line is 0
Answer:
6
Step-by-step explanation:
21 - 15 = 6
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
Answer is C. 7/12 has the reciprocal of 12/7. When You multiply by a reciprocal, you just switch the numerator and denominator. The answer does NOT become negative. It would change the fraction itself.
