Answer: Supplementary Angles. Two Angles are Supplementary when they add up to 180 degrees.
Step-by-step explanation:
By "-21x + 9 + y equals -24x + 8" I'm assuming you meant
"y = -21x + 9 AND y equals -24x + 8." Using " + " to indicate "and" could be confusing.
We then have the system of linear equations
y = -21x + 9
y = -24x + 8
The function with the greater slope is the 2nd: y = -24x + 8 (with the understanding that we're focusing on the magnitude of the slopes). Thus, it is this function that changes more quickly.
Answer:
B) 12 hours
Explanation
Max can read 150 words per minute. 350 words per page divided by 150 is 2.333, so max can read 1 page in around 2 minutes. There are 310 pages. 2.333 * 310 is around 723. 723 minutes converted to hours is 12 hours. Boom. Done.
What money? BAHAHA UR BROKEKEKEKE
First, add all the numbers together, the answer is -27.
Then, divide by the amount of numbers in the data set, in this case 9.
-27/9=-3
