Answer:
it stays the same until t=0, where it is undefined
Step-by-step explanation:
2t/t = 2 . . . . when t ≠ 0
2t/t = undefined when t = 0.
The value of t can increase or decrease and the value of the ratio remains the same. The value has a "hole" at t=0, where it is undefined. Otherwise, its value is always 2.
Y doesn't change so it stays 3.
x will be 0, because the average of 0 and -2 is -1
Answer:
B
Step-by-step explanation:
1. Given mathematical statement
![4x+3=x+5-2x](https://tex.z-dn.net/?f=4x%2B3%3Dx%2B5-2x)
So,
![\begin{array}{cc}4x+3=x+5-2x&\text{ Given}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D4x%2B3%3Dx%2B5-2x%26%5Ctext%7B%20Given%7D%5Cend%7Barray%7D)
2. Rewrite it as
![4x+3=x-2x+5](https://tex.z-dn.net/?f=4x%2B3%3Dx-2x%2B5)
So,
![\begin{array}{cc}4x+3=x-2x+5&\text{ Commutative property of addition}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D4x%2B3%3Dx-2x%2B5%26%5Ctext%7B%20Commutative%20property%20of%20addition%7D%5Cend%7Barray%7D)
3. Combine like terms
and ![-2x:](https://tex.z-dn.net/?f=-2x%3A)
![4x+3=-x+5](https://tex.z-dn.net/?f=4x%2B3%3D-x%2B5)
So,
![\begin{array}{cc}4x+3=-x+5&\text{ Combine like terms}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D4x%2B3%3D-x%2B5%26%5Ctext%7B%20Combine%20like%20terms%7D%5Cend%7Barray%7D)
4. Add
to both sides:
![4x+3+x=-x+5+x\\ \\5x+3=5](https://tex.z-dn.net/?f=4x%2B3%2Bx%3D-x%2B5%2Bx%5C%5C%20%5C%5C5x%2B3%3D5)
So,
![\begin{array}{cc}5x+3=5&\text{ Addition property of equality}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D5x%2B3%3D5%26%5Ctext%7B%20Addition%20property%20of%20equality%7D%5Cend%7Barray%7D)
5. Subtract 3 from both sides:
![5x+3-3=5-3\\ \\5x=2](https://tex.z-dn.net/?f=5x%2B3-3%3D5-3%5C%5C%20%5C%5C5x%3D2)
So,
![\begin{array}{cc}5x=2&\text{ Subtraction property of equality}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D5x%3D2%26%5Ctext%7B%20Subtraction%20property%20of%20equality%7D%5Cend%7Barray%7D)
6. Divide both sides by 5:
![x=\dfrac{2}{5}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B2%7D%7B5%7D)
So,
![\begin{array}{cc}x=\dfrac{2}{5}&\text{ Division property of equality}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7Dx%3D%5Cdfrac%7B2%7D%7B5%7D%26%5Ctext%7B%20Division%20property%20of%20equality%7D%5Cend%7Barray%7D)
Answer:
1
Step-by-step explanation:
-4 because it is closer to the 0
