Answer:
A and C
Step-by-step explanation:
Perpendicular lines have reciprocal and opposite slopes.
First slope =3,
Second = -3
Third slope = -1/3 (which is opposite and reciprocal to the first)
Last slope = -3
This expression is a difference of squares:

There are 95 ounces and 5.9375 pounds.
Answer:
answer is subtract the 180-120=80
Answer:
- 39/8y
Step-by-step explanation:
First you need to find a common denominator:
There is already a y in both denominators, so you don't have to worry about that. Since only one denominator has an 8, the other needs to have an 8, so you need to multiply the first fraction by 8 → - 4/y * 8 = - 32/8y
From here you can subtract the numerators:
- 32/8y +(- 7/8y) = - 39/8y
Because you are adding a negative to a negative, it makes the number mroe negative
I hope this helps!
