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:
Step-by-step explanation:
(-13 - 7)/(-1 + 3) = -20/2 = -10
y - 7 = -10(x - 3)
y - 7 = -10x + 30
y = - 10x + 37

Answer:
(c) 5, 4, 11
Step-by-step explanation:
The sum of the two short sides must exceed the long side. That is not the case for ...
5 + 4 = 9 < 11
The lengths 5, 4, 11 cannot be a triangle.
Okay. So, Amber used 1/2 of the 4/5 bag for the art project. Let’s do 4/5 / 2. 4/5 * 1/2 is 4/10 or 2/5 in simplest form. Amber uses 2/5 of a pound of sand for her art project.
