From the conditions given, the total number of the problems should be 29. This means that the sum of x and y should be 29. With this and the point-system, the best system of equation that is useful for this problem is,
x + y = 29
5x + 2y = 100
The answer is the second choice.
The answer to this question will be D
For the first one, remember that the parent function is y = x² for a parabola. The modifications made are the subtraction of five from the square of x, and the square of x is also being multiplied by two.
For the second one, look at the roots (Where the graph crosses the x - axis). From them, we can create a function with the following steps:
1.) Put the two roots into monomials:
(x - 1)(x - 3)
2.) Multiply them together with FOIL (First, Outside, Inside, Last):
x² - 3x - x + 3
x² - 4x + 3
3.) You have your answer!
x² - 4x + 3

Answer:
Brad pays more than Colleen by %1.84
Step-by-step explanation:
30 multiplied by 1.08 (1.08 is the original price plus the 8% tax) is 32.4. 32 multiplied by 1.07 is equal too 34.24.
