Between 2 and 3, after the 2 1/4 point, but before the halfway point.
Answer:
5 = |-5|
Step-by-step explanation:
Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.
Refer to the picture below for an illustration:
Domain: What are all the possible x values?
[-6, 0) U (0,2)
[ ] Closed brackets means including a number
( ) Open brackets means not including that number
Range: All possible y values
(1, 6]
Answer:
21
Step-by-step explanation:
First you have to solve for x in the equation 2x + 9 = 23. Cancel 9 on both sides. You cancel 9 by subtracting 9 on the left side and on the right side:
23 - 9 = 14.
Now, you have 2x = 14. To isolate the variable, divide by 2 to cancel out 2.
14 / 2 = 7.
This will give you x = 7. Now that you know what x equals, you can substitute x in 3x. This would make it 3(7), or in other words 3 x 7.
3 x 7 = 21.
This means that 3x would be equal to 21. Hope it helps!
The function is equal to y(an unknown number) is equal to 1 times a(another unknown number)But since anything times one is itself, it is equal to y=y so that means NO it is not a function.
