You would subtract the x's from each other and subtract the y's from each other. X= 3-(-3)=6 Y=-4-4=-8 so the slope would be -8/6 or if you simplify it -4/3
Answer:
A.) $2.52 less per pound. B.) $13.08 more
Step-by-step explanation:
A.) You pay $14.82 for 1.5 lbs of ham. You divide $14.82 by 1.5 lbs (14.82/1.5) to figure out how much you spend per pound of ham. You should get $9.88. Since you spend $12.40 per pound of roast beef, you subtract $9.88 from $12.40 ($12.40 - $9.88). You should get $2.52, which is your answer.
B.) Since you paid $14.82 for 1.5 lbs of ham, you already have this variable. Take the 2.25 lbs of roast beef and multiply it by $12.40 per pound (12.40*2.25). You then take that number ($27.90) and subtract it by $14.82 (27.90-14.82) and you should get your answer, $13.08.
Answer: Product of powers
---
The product of powers rules basically says that two powers, let's call them
and
, with the same base (a) multiplied together equals
.
In your problem you can see that
and
are being multiplied together and the exponents are being added, which is what the "product of powers" law says.
EQUATION: 5x = 2x - 9
Add 9 to both sides
NEW EQUATION: 5x + 9 = 2x
Subtact 5x from both sides:
NEW EQUATION: 9 = -3x
Divide -x on bith sides
NEW EQUATION: -3 = x, or x=-3
