Answer:
D.

Step-by-step explanation:
since it is an exponential graph shifted 7units to the left would be

The perimeter is 46cm
you find the width by dividing the area by the length and then add the length and width times 2 to get the perimeter
In exact form it would be 15/8
Answer:
In step 2, she didn’t use an x and y from the same coordinate pair
Step-by-step explanation:
see the attached figure to better understand the problem
we have the points (5, 1) and (3, 5)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute
step 2
The equation of the line in point slope form is

take the point (3,5)
substitute



step 3

therefore
In step 2, she didn’t use an x and y from the same coordinate pair
