<h3>
Answer: 50%</h3>
Work Shown:
change = new - old = 189-126 = 63
percent increase = (change/old)*100%
percent increase = (63/126)*100%
percent increase = (0.50)*100%
percent increase = 50%
50% of 126 = 0.50*126 = 63
126+63 = 189
The answer is confirmed.
Answer:
x = 13
Step-by-step explanation:
Take the square root of both sides
Answer: Yes, y does vary directly with x.
Constant of variation = 1/4
The function rule is y = (1/4)x
=========================================================
Explanation:
Let's assume that y does vary directly with x.
If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.
Solving for k gets us k = y/x
For each row, divide the y value over the x value
- row one: k = y/x = 14/56 = 0.25
- row two: k = y/x = 20/80 = 0.25
- row three: k = y/x = 22/88 = 0.25
Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.
So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x

Answer:
2xy+10z-5yz-4x
Step-by-step explanation:
Just put the positives and negatives together. You can't add or subtract any of them because they aren't like terms.
