The equation you have to solve is 1.50 + (0.75 • 6). First, you solve what is in the parenthesis, 0.75 • 6 = 4.50. Now you simply add 1.50 and 4.50 to get $6, the total cost for 7 hours worth of parking.
I don't remember the names of the theorems at all, but we know that AD ≈ DE ≈ EB (Segment Addition). Which means <ACD ≈ <DCE ≈ <ECB (not completely sure how to prove this). Therefore, <1 ≈ <2. (Don't forget to state that <1 ≈ <ACD and <2 ≈ <ECB). With this and Angle Addition, we know that <ACE ≈ <DCB, so with SAS Congruence Theorem, we can prove ΔACE ≈ ΔBCD.
Hope that helps
Answer:
The answer to your question is letter C. 7y³ + 7n²y² - 22y²
Step-by-step explanation:
y²(4y + 7n² + 2) - 3y² (-y + 8)
Multiply
4y³ + 7n²y² + 2y² + 3y³ - 24y²
Use the associative property for like terms
(4y³ + 3y³) + (2y² - 24y²) + 7n²y²
Simplify like terms
7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²
The answer in slope-intercept form would be:
y=1/3x-3
