You multiply 38*$7.25 equals $275.5
Subtract new weekly gross pay raise with regular gross pay
$307.80-$275.5= $32.3 cents in raise
Answer:
negative correlation
Step-by-step explanation:
The simplification of rational expressions is explained
<u>Solution:</u>
Rational expressions are fractions that have a polynomial in the numerator, denominator, or both.
Rational expressions contain variables, they can be simplified in the same way that numerical fractions are simplified.
<em><u>Steps to simplify rational expressions:</u></em>
Let us see it with an example:
![\frac{3 x^{2}-3 x}{3 x^{3}-6 x^{2}+3 x}](https://tex.z-dn.net/?f=%5Cfrac%7B3%20x%5E%7B2%7D-3%20x%7D%7B3%20x%5E%7B3%7D-6%20x%5E%7B2%7D%2B3%20x%7D)
1) Look for factors that are common to the numerator & denominator
![\frac{3 x(x-1)}{3 x\left(x^{2}-2 x+1\right)}](https://tex.z-dn.net/?f=%5Cfrac%7B3%20x%28x-1%29%7D%7B3%20x%5Cleft%28x%5E%7B2%7D-2%20x%2B1%5Cright%29%7D)
2) 3x is a common factor to the numerator & denominator. Note that it is clear that x ≠0
3) Cancel the common factor
![\frac{x-1}{x^{2}-2 x+1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7Bx%5E%7B2%7D-2%20x%2B1%7D)
4) If possible, look for other factors that are common to the numerator and denominator
![\frac{x-1}{(x-1)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7B%28x-1%29%28x-1%29%7D)
5) After cancelling, you are left with ![\frac{1}{(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%28x-1%29%7D)
6) The final simplified rational expression is valid for all values of "x" except 0 and 1
We have to follow the same procedure for any rational expression.
Answer:
The same slope and different y-intercepts.
Step-by-step explanation:
If the slope is different, they will collide.
If the y-intercept is the same, there will be infinite solutions.
