Answer:
<h2>
9x+18</h2><h2>
</h2>
Reasoning:
You multiply x by 9 and 2 by 9 and it expands out from 9(x+2) to 9x+18

I hope this helps and good luck!
Answer:
48
Step-by-step explanation:
7-1=6 6 times height which is 8 is 48.
70) perpendicular means you take the number in from of the x and flip it and switch the sign. that number will become your slope (m).
y=mx+b. plug in slope and point
-5=(7/9)(-4)+b. multiply
-5=(-28/9)+b. add over -28/9
b= -17/9. plug b and slope into original equation
y=(7/9)x+(-17/9) get rid of frac by multi by 9
(y=(7/9)x+(-17/9))*9
9y=7x+-17. subtract over 7x
-7x+9y=-17. answer
Same goes for the rest. number 72 the perp slope will be (1/3) and for 74 the answer will be x=-5 (that is a weird case)
Answer:

Step-by-step explanation:
Given
(every hour)
Required
Explain why it is linear
First, we need to determine the equation that represents the scenario
Let x be the number of hours worked and y be the number of figurines at x hours.
The equation is determined as follows:
This gives:
Reorder
A linear equation is of the form
By comparison,
is equivalent to
<em>Hence, we can conclude that the situation is linear</em>
Answer:
the range of the data set is 5.9
Step-by-step explanation:
1.9, 2.3, 2.6, 3.1, 3.5, 3.7, 4.5, 4.7, 7.8
7.8-1.9=5.9
