Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
Answer:
this is easy just do 12-(-8)= 12+8=20
so the answer is 20
Step-by-step explanation:
Answer:
5(30 + 2)
Step-by-step explanation:
5(32)=160
5(30+2)=160
The rest equal different numbers
The point-slope form is y - y1 = m(x - x1) where x1 ad y1 are the coordinates given and the m is the slope, which is given also. Plugging these in, we have
y - 4 = -2(x - (-1)), which simplifies to y - 4 = -2(x + 1)
Answer:
60 lb
Step-by-step explanation:
Represent the weights of the dogs by P and C. Then P = 3C.
Then P + C = 80, or, after substitution of 3C for P,
3C + C = 80, or
4C = 20, so that C = (20 pounds)
Paula's dog weighs 3 times as much as Carla's: P = 3(20 lb) = 60 lb
