Answer:
First, Multiply 5 by 3 to get how much the temperature decreased.
5*3=15
Then, add 7 to 15 to get the total amount how much the temperature decreased.
15+7=22
The answer to your question is 22.

Answer:
A: ∠W'Z'Y' = 60°; angles aren't changed by rotation
B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)
Step-by-step explanation:
<u>Part A</u>:
Angle WZY is the supplement of the given angle ZWX, so is ...
∠WZY = 180° -120° = 60°
Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...
∠W'Z'Y' = 60°
__
<u>Part B</u>:
The transformation right 2 and up 3 can be described by ...
(x, y) ⇒ (x +2, y +3)
Then the translated vertices are ...
W(-5, 3) ⇒ W'(-3, 6)
X(7, 3) ⇒ X'(9, 6)
Y(6, -2) ⇒ Y'(8, 1)
Z(-6, -2) ⇒ Z'(-4, 1)
Y=2x−4 is the graph so you graph it
Answer:
~427$
Step-by-step explanation:
1. Subtract the 20% price -> 499*0.8=399.2$
2. Add the 7% tax -> 399.2*1.07=427.144$
