Answer:
Step-by-step explanation:
1. asks you to add the two functions and , which would be
Simplify the like-terms and you get:
------------------
2. asks you to multiply the two functions and , which would be
In order to multiply the functions we use the FOIL method (for polynomials):
Multiply each term and you get:
Simplify the like-terms and you get:
------------------
3. asks for your ability to understand what composite functions are. In order to solve this, we will follow some careful steps and solve them separately.

Now that we have both values, we can just subtract them:
Answer:
$450 is the original price
Step-by-step explanation:
We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked down by 30% so we pay 70% of the original. The sale price is $315.
We begin solving by cross multiplying numerator to denominator of each fraction.
Segment subtraction (three total segments): If a segment is subtracted from two congruent segments, then the differences are congruent. Angle subtraction (three total angles): If an angle is subtracted from two congruent angles, then the differences are congruent.
