Median is the middle number.
Rearrange the numbers to smallest to biggest.
70, 77, 80, _, 82, 87, 88
If the median of the data set is 81 the middle number needs to be 81.
So the missing number is 81.
70, 77, 80, 81, 82, 87, 88
Answer:
Goodluck I had this before and couldn't get it
I disagree, because a function can have a slope of zero and be neither increasing nor decreasing.
Answer:
the first question would be y= -1/4x + 8
the second one would be 3x + 5y = -65
the third one would be y= -2
and last but not least... the last one would be b.
Step-by-step explanation:
4x² - 3xy + 9y² - 3(5xy + 7y²)
4x² - 3xy + 9y² - 3(5xy) - 3(7y²)
4x² - 3xy + 9y² - 15xy - 21y²
4x² - 3xy - 15xy + 9y² - 21y²
4x² - 18xy - 12y²
