Answer:
-4
Step-by-step explanation:
t2 - t1
-13 - (-9)
-13 + 9
= -4
The price difference/ the original price and times the whole equation by 100 (to get the percentage).
> ($50/$150) x 100 = 33% (rounded)
P(a U b) = p(a) + p(b) - p(a ∩ b)
<=>
p(a ∩ b) = p(a) + p(b) - p(a U b)
I let you do the maths :)
Substitute y = -2x + 4 into 7y = -14x +28
7y = -14x +28
7(-2x + 4)= -14x +28
-14x + 28 = -14x +28
0 = 0
answer
infinitely many solutions
396 divided by 12 will be 33
