Answer: There are 20 used bikes
Explanation: If there are 4 times the used bikes then you would have to do 80 divided by 4 and there’s the answer
Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11

Step-by-step explanation
I did this today and it's easy but you have to show a lot of work well I did but you don't have to you can just circle it in
Answer:
Here x=10° ,2x=20° ,5x=50°
