Answer: (0,-15)
--------------------------------------------------
Explanation:
Add up the x coordinates to get 1+(-1) = 0. Divide this sum in half to get 0/2 = 0. Therefore the x coordinate of the midpoint is 0.
Repeat for the y coordinates. First add the y coordinates to get -7+(-23) = -30. Then divide that result in half to get -30/2 = -15. So the y coordinate of the midpoint is -15.
Overall, the midpoint is (0,-15).

- Range is the set of y-values that are outputted by function f(x)
- {Set Builder Notation}
Step-by-step explanation:
<u>Step 1: Define</u>
[Relation] {(-4, 1), (-2, 0), (8, -1)}
<u>Step 2: Identify</u>
According to the relation, our y-values are 1, 0, and -1. These values would encompass our range.
Let's solve for k. (-m)(k) - 90>85
step 1: add 90 to both sides.
-km -90+90> 85+90
- km > 175
step 2: divide both sides by -m
-km >175
-m -m
K< -175
m
Answer:
sales tax: $10.49
Total: sales tax+charges = $160.29
Step-by-step explanation:
to find out sales tax, follow formula
Tax $ = OG $ x Tax%
*usually easier to convert % to decimal if calculator does not have % option*... to convert % to decimal.. move two decimals to left and vice verse decimal to % will be two decimals to right*
ex. 7% = .07
36 is perfect square because 36 = 6*6
64 is perfect square because 64 = 8*8
