Answer:
<em>d = 3</em>
Step-by-step explanation:
Coordinate Plane
The image provided shows the four points given:
A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).
It can be clearly seen the length of CD is just the difference of their x-coordinates:
CD = 7 - 4 = 3
We can also use the formula of the distance.
Given two points C(x,y) and D(w,z), the distance between them is:




d = 3
Answer:
Option A, -15
Step-by-step explanation:
<u>Step 1: Look at the function that needs to be outputted when x = -3</u>
Since x = -3, that means it falls into the first category of x ≤ -3
<u>Step 2: Carry out the instructions</u>
The function for the first category is 



Answer: Option A, -15
