Answer: x = 7 or x = -8
x² + x - 56 = 0
⇔ x² + 8x - 7x - 56 = 0
⇔ x(x + 8) - 7(x + 8) = 0
⇔ (x - 7)(x + 8) = 0
⇔ x - 7 = 0
or x + 8 = 0
⇔ x = 7 or x = -8
Step-by-step explanation:
Answer:
y=x
Step-by-step explanation:
Something that would create a direct proportionality is y=x because both of them are in an equation which means they are directly proportional

<u>Answer:</u>
The correct answer option is C. 0.
<u>Step-by-step explanation:</u>
We are given the following data set and we are to find its median value:

Median is the middle value of a data set which divides it into to halves.
The data set we have starts from -1000 and goes till 1000 which means there are total 2001 elements in it.
Therefore, 0 will the middle value which is the median for this data set.
