You plug in the x = 3y+4 into the 3x part of 3x -5y=8. You distribute the 3 and add like terms to end up with 4y=12. You divide by 4 to get y alone and get -1. That’s your y value. You plug that -1 into the y part of any of the two equations to find x. The simplest one is to plug it in to x=3y+4, and you get -3+4=x, so x= -1
Unbalanced is the answer

Given:
6/7(7/6z)
First, you would have to multiply both fractions together:
6/7(7/6z) = 42/42z
Next, simplify:
1z
(Since 42/42 is a bit redundant, you would then simplify to 1z)
Finally, you can either leave the answer as 1z or you can just leave it as z, because in math, variables have an imaginary 1 in front of them so the 1 is not necessary.
Answer: z
I hope this helps!
C. is the correct answer, because both numbers are increasing.
Therefore, C. represents a linear increasing function.
Answer:
Step-by-step explanation:
a) 6 out of 10 are shaded. 6/10 = 60/100 so it is 60%
b) 11 out of 20 are shaded. 11/20 = 55/100 so it is 55%
