Answer:
<u>First, find the cost function of DoItRight Housekeeping:</u>
- Slope(m) = cost per hour =
![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{44-26}{3-1.5}=\frac{18}{1.5}=12](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%3D%5Cfrac%7B44-26%7D%7B3-1.5%7D%3D%5Cfrac%7B18%7D%7B1.5%7D%3D12)
<em>The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:</em>
![f(x)=12x+b\\26=12(1.5)+b\\b=26-18=8](https://tex.z-dn.net/?f=f%28x%29%3D12x%2Bb%5C%5C26%3D12%281.5%29%2Bb%5C%5Cb%3D26-18%3D8)
<u>Therefore, the function for two companies are:</u>
- The function for DoItRight is
![f(x)=12x+8](https://tex.z-dn.net/?f=f%28x%29%3D12x%2B8)
- The function for CleanIt is
![g(x)=10x+16](https://tex.z-dn.net/?f=g%28x%29%3D10x%2B16)
When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.
Answer:
The last one..Number 4
Step-by-step explanation:
When u add the two sides it's supposed to be larger than the bigger side
so 13+20 is smaller than 34
Answer:
Alright the answer is 40

Option 2 is your answer
Your numbers on the left are going across. Then the numbers on the top are going down
Step-by-step explanation:
slope is y2-y1/x2-x1
formula is
y=mx+b where m is the slope
