Answer:</h2>
The average speed of car is:
0.75 miles per minutes.
The equation of line is:

<h2>
Step-by-step solution:</h2>
The table that describes the time and number of miles marked is given by:
Time Miles
0 0
4 3
8 6
Clearly we could observe that with the increase in time by every 4 minutes the number of mile increases by 3.
i.e. the average speed is calculated as the ratio of change in miles to the change in time.
Hence,

Hence, the average speed=0.75 miles per minutes.
Also we will find the equation of the lines that related the miles and time by using the two-point formula.
i.e. any line passing through (a,b) and (c,d) is calculated by using the formula:

Here (a,b)=(0,0) and (c,d)=(4,3)
i.e. the equation is given by:
The answer is A. because for you to find the answer you have to subtract so it would be 55.75-12.5=43.25
Answer:
she can get 12 books
Step-by-step explanation:
if you divide 18 by 3 you get 6
and if you times that my 2 get 12
so your answer is 12 books
Answer:
The answer is below
Step-by-step explanation:
We are asked to find the perimeter of triangle CDE. The perimeter of a shape is simply the sum of all its sides, hence:
Perimeter of tiangle CDE = |CD| + |DE| + |CE|
Given that C(4, -1), D(4, -5), E(2, -3).
The distance between two points
is given as:

Therefore the lengths of the triangle are:

Perimeter of CDE = 4 + 2.83 + 2.83 = 9.66 units
The conversion factor should be multiplied in Step 2 instead of being divided.
