What I did to solve this is finding the equation of the line using slope intercept form y is the cost of the ride which increases as you increase mileage or move along the X axis. My points are (2, 5.25) and (5,10.5)
<span>y=mx+b </span>
<span>m=y2-y1/x2-x1 </span>
<span>m=(10.5-5.25)/(5-2) </span>
<span>m=5.25/3=1.75 or 7/4 </span>
<span>y=7/4x+b enter one point for the values of x and y to find b </span>
<span>10.5=(1.75X5) + b </span>
<span>10.5=8.75 + b </span>
<span>b=1.75 </span>
<span>The equation of the line is y=7/4x+1.75 (I also double checked using the second point) </span>
<span>Then all you have to do is enter the mileage 3.8 for the value of X and solve for y </span>
<span>y=(7/4 X 3.8) + 1.75 </span>
<span>y=6.65+1.75 </span>
<span>y=8.4 The cab ride for the 3.8mile trip is $8.4
I hope this helps</span>
Answer:
165
Step-by-step explanation:
Because you can't order 7/8 of a pizza you would have to order 165 pizzas so that every body gets one slice. Hope this helped!

Step-by-step explanation:
Bro, for the $500 after the rate add 12 and 12 and do that for all the rate's like when you get to the fraction rate add the fraction rate with the fraction rate
Answer:
21n² - 28n + 7
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
3n(7n - 7) - 1(7n - 7) ← distribute both parenthesis
= 21n² - 21n - 7n + 7 ← collect like terms
= 21n² - 28n + 7
