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
I don’t understand how you worded the question but x=-4 if thats what you are looking for
Answer:
D) √15
Step-by-step explanation:
An irrational number is a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient of two integers.
