Answer:
7
Step-by-step explanation:
It is 7:
31 - 7 = 24
15 - 7 = 8
8/24 = 1/3 = 33%
It is not 12:
31 - 12 = 19
15 - 12 = 3
3/19 = 15%
It is not 6:
31 - 6 = 25
15 - 6 = 9
9/25 = 36%
It is not 9:
31 - 9 = 22
15 - 9 = 7
7/22 = 31%
It is not 11:
31 - 11 = 20
15 - 11 = 4
4/20 = 20%
<u>I subtracted the option from 31 (the new total of marbles) and from 15 (the new total of blue marbles). Then, I divided the new total by the new total of the blue marbles. I converted the decimal into a percentage. If the percentage was not 33%, then it was not the answer.</u>
Answer:
y = -10.375x + 126.125
Step-by-step explanation:
(12-95)/(11-3) = -83/8 = -10.375
y = mx + b
12 = -10.375(11) + b
12 = -114.125 + b
b = 126.125
y = -10.375x + 126.125
The correct answer is A.
The independent variable is time and the dependent variable is distance; this means the slope tells us how far she goes per minute. Since the slope is negative and we are referring to her distance from her house, this means the distance from her house is decreasing, which means she is getting closer to her house.
Answer:
-2
Step-by-step explanation:
Equate the expressions for y. This gives ...
... x - 1 = 2x + 1
Add -1-x to get ...
... -2 = x . . . . your value of x
