Answer:
<u>No, it's not a function.</u>
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. <u>Therefore, this is not a function.</u>
Answer: 4 feet
Step-by-step explanation:
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5

Step-by-step explanation:
We would have to see the graph but I know it's either B or C because the other answer choices don't make sense. I chose B because it seems like the most logical choice of the two.
Answer:
25%
Step-by-step explanation:
Lets figure out how many students total in Lorenzo's grade:
7 students + 21 students = <u>28 total students</u>
<u />
We know that we can find the percentage by dividing our value by the total amount and multiplying it by 
, which is 1. (Multiplying by 1 does not change anything, which is why we choose to do this.)
Taking our known values,
<em>Therefore, </em><em>25%</em><em> of students voted for the athlete.</em>
