Just as you can perform the four operations on polynomials with one variable, you can add, subtract, multiply, and divide polynomials with more than one variable. The process is exactly the same, but you have more variables to keep track of. When you are adding and subtracting polynomials with more than one variable, you have to pay particular care to combining like terms only. When you multiply and divide, you also need to pay particular attention to the multiple variables and terms. You can multiply and divide terms that aren’t like, but to add and subtract terms they must be like terms
Answer:
it would be 28y minus 3
Step-by-step explanation:
Our line equation is
where the slope m=1/2 and the y-intercept b is b=7.
Parallel lines has the same slope. Hence, their slope is always
in this case.
Answer:
The compound interest one is better by about 14 bucks.
Step-by-step explanation:
Simple interest:
500(1+.06*10)=800
Compound interest:
500(1+.05)¹⁰=814.45
A. PT and TQ are equal since they are both bisected by T. So, set them equal to each other you get the equation:
5x+3 =48
5x=45
x=9
