Answer:

4: No

5: A

Step-by-step explanation:

4: The mapping does now represent a function. In a function each x value can only have 1 corresponding y value ( meaning that the x values can not repeat.) In the mapping the x value 3 corresponds with 2 y values therefore the mapping is not a function.

5.

Formula for volume of a cylinder = V=\pi r^2h

Where r = radius and h = height

The cylinder shown has a given diameter of 22ft and a given height of 10ft

In order to use the formula we must convert the diameter to radius.

To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )

so radius = 22/2 = 11

Now we plug in the dimensions into the formula

V=\pi 11^210\\11^2=121\\121*10=1210\\1210\pi

Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π

We can conclude that the answer is A

Answer:

3g + 9g =  - 48 \\ 12g =  - 48 \\ g =  -  \frac{48}{12}  \\ g =  - 4 \\  \\   - 4m - 6m - 30 =  - 80 \\  - 4m - 6m =  - 80 + 30 \\  - 10m =  - 110 \\ m =  \frac{ - 110}{ - 10}  \\ m = 11 \\  \\ 12 =  - 8n - 24 - 4n \\ 12 + 24 =  - 8n - 4n \\ 36 =  - 12n \\ n =  \frac{36}{ - 12}  \\ n =  - 3 \\  \\ 5y + 2y +  \frac{1}{2}  =  -  \frac{1}{2 }  \\ 5y + 2y =   - \frac{1}{2}   -  \frac{1}{2}  \\ 7y =  - 1 \\ y =  -  \frac{1}{7}  \\  \\ 22x + 0.25 - 16x = 0.85 \\ 22x - 16x = 0.85 - 0.25 \\ 6x = 0.6 \\  x =  \frac{0.6}{6}  \\ x = 0.1 \\  \\ 17k + 6k + 11 = 80 \\ 17k + 6k = 80 - 11 \\ 23k = 69 \\ k = 3

Need help on number 25 and 26 can you please explain how you got the answer thanks!:)
Westkost [7]
In both problems, the sum of side lengths is the perimeter. Opposite sides of a parallelogram (or rectangle) are equal in length, so you can find the perimeter by doubling the sum of adjacent sides.

25. 2(x +(x +15)) = (x +45) +(x +40) +(x +25)
.. 4x +30 = 3x +110 . . . . . . . . . . . . . . . . . . . . . . simplify
.. x = 80 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subtract 3x+30
.. 4x +30 = 4*80 +30 = 240
The perimeter of each is 240 units.

26. 2(x +(x +2)) = (x) +(x +6) +(x +4)
.. 4x +4 = 3x +10 . . . . . . . . . . . . . . . . . . . . . . simplify
.. x = 6 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subtract 3x+4
.. 4x +4 = 4*6 +4 = 28
The perimeter of each is 28 units.
