Answer:
y=3/4x-2
Step-by-step explanation:
Slope= 3/4
y-intercept= -2
Answer:
B
Step-by-step explanation:
It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.
What is the first quartile of the following data set? 12, 33, 15, 22, 29, 11, 17, 19, 10, 24, 38

First, organize the numbers in numerical order:
10, 11, 12, 15, 17, 19, 22, 24, 29, 38
Then, find the mean: which is the middle of the data set. The middle lies right between 17 and 19, which is 18.
The first quartile is the middle of the first half. Which is the number 12.
Answer:
8n³ + 10n² - 13n - 15
Step-by-step explanation:
Distribute the factors by multiplying each term in the first factor by each term in the second factor, that is
4n(2n² + 5n + 3) - 5(2n² + 5n + 3) ← distribute both parenthesis
= 8n³ + 20n² + 12n - 10n² - 25n - 15 ← collect like terms
= 8n³ + 10n² - 13n - 15
