4y-17=43
move -17 to the other side
sign changes from -17 to +17
4y-17+17=43+17
4y=43+17
4y=60
divide both sides by 4 to get y by itself
4y/4=60/4
answer:
y=15
Assuming that each candle costs the same amount, we divide total cost by the amount of the candles bought. $36/12 candles. Your final answer would be $3 per candle.
First find the slope of A.
Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7
For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A. Mathematically:
m1*m2=-1 and in this case the perpendicular line will have a slope of:
4m/7=-1
4m=-7
m=-7/4
So the slope of the line perpendicular to A is -7/4
Answer:
stocks, bonds, mutual funds, and collectables
Step-by-step explanation:
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (5, - 8)
m =
=
= 0
