Add the mileage together to find total miles.
Add the hours together.
Divide total miles by total hours.
305 + 190 = 495 miles
5 + 4 = 9 hours.
495 / 9 = 55 miles per hour.
The average speed was 55 miles per hour.

Step-by-step explanation:
A dilation will always create an image smaller or bigger than the pre-image making it not congruent since it changes in size.
Answer:
a = 
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a =

Step-by-step explanation:
<u>The Equation of a Line</u>
The equation of the line in slope-intercept form is:

Where m is the slope and b the y-intercept.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

We are given the points (5,2) and (0,-1), thus:

Operating:


To find the slope-intercept form, we continue to simplify the expression:
Removing the parentheses:


Adding 2:
