Rational expressions are often used in combining rates of work. Therefore, it's true.
<h3>What is rational expression?</h3>
It should be noted that a rational expression is simply defined by a rational fraction.
They're are used in combining rates of work. Fir example, if Mr John performs 1/2 of his work and does 1/3 on another day. This can be expressed as:
= 1/2 + 1/3
= 5/6

Answer:
<h2>x-intercept = 6 → (6, 0)</h2><h2>y-intercept = 6 → (0, 6)</h2>
Step-by-step explanation:
x + y = 6
x-intercept is for y = 0. Substitute:
x + 0 = 6
x = 6
y-intercept is for x = 0. Substitute:
0 + y = 6
y = 6

HOPE THAT HELPS!!!!!!!
Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.
We are told to use j as the original price of the jeans, so we can set up the expression:
to represent the cost of the jeans with the discount.
Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:
or 
Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:
Therefore, the cost of the jeans after the discount is C) $45.
