Answer:
(-5, 0) and (0,4)
Step-by-step explanation:
Given equation: -4x + 5y = 20
Sub. in the values
When x = -5 and y = 0 (-5,0),
When x = 0 and y = 4 (0,4),
That's how I would do it, not sure if your school has another method. Hope this helps :)
Answer:
9:5
Step-by-step explanation:
- 112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.
- Find the GCF of 72 and 40, which is 8.
- Divide 72 and 40. The simplified ratio is 9:5.
B. The horizontal asymptote is at y = -4.
D. There is an x-int at approximately (1.3, 0)
Circumference = 2pi*r
If 12pi = 2pi * r,
r = 6
So area is pi * 6^2 = 36pi
