Answer:
A
Step-by-step explanation:
This is a strict inequality so the line must be dotted, meaning it can only be A or D.
The inequality says that y is less than -2x+4 so we want the region under the line, making A the correct answer.
Answer:
Yes; domain: all real numbers; range: y 0
Step-by-step explanation:
1. Use the vertical line test to see if it is a function.
2. Figure out what the lowest and highest point x can be. In this case x can be any number
3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y 0
*Note: Domain are the x values & Range are the y values
PROBLEM 9:
0.25
PROBLEM 8:
3/14
PROBLEM 7:
1 1/12 or 13/12
If you mean something like 4^3 * 4^14 you have to obey two rules.
1. The base number must be the same for both numbers making up the product.
2. The powers must be added.
In this case 1 and 2 both can be obeyed.
4^3 * 4^14 = 4^(3 + 14) = 4^17
