Answer:
5x -3y = 44
Step-by-step explanation:
We choose to start with the form ...
(Δy)x -(Δx)y = (Δy)(x1) -(Δx)(y1) . . . . . where Δy = y2 -y1 and Δx = x2 -x1
For this purpose, it is convenient to choose y2 > y1, so we have ...
Δy = -3 -(-8) = 5
Δx = 7 -4 = 3
5x -3y = 5(4) -3(-8)
5x -3y = 44
Answer:
Step-by-step explanation:
5 * 5 * 5 * 5
= 625
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
