Multiply all of the numbers together: 5 x 2 x 8 = 10 x 8 = 80 ways
Answer:
Y=4
Step-by-step explanation:
The line is horizontal, which means that variable would be 4. The line starts at 4, which mean the equivalent of the variable is 4.
Answer:
One of the negatives must go
Step-by-step explanation:
Answer:
y = 6/(x - 8).
Step-by-step explanation:
z = k/y where k is a constant
2 = k/3
k = 6.
So z = 6/y
and x = 6/y + 8
Multiply through by y:
xy = 6 + 8y
xy - 8y = 6
y(x - 8) = 6
y = 6/(x - 8)
If a=0, then the denominator is equal to 0. Since you cannot divide by zero, you are not allowed to do this.
Hope This helps!
