Answer:
a) x changes by 6.5 units
b) y changes by 13 units
Step-by-step explanation:
a. Over this interval, how much does x change by?
Initially, we have that x = 2.
In the end, we have that x = 8.5.
So x changes by 8.5-2 = 6.5 units
b. Over this interval, how much does y change by?
Initially, when x = 2, we have that y = 2x + 11 = 2*2 + 11 = 15
In the end, when x = 8.5, we have that y = 2*8.5 + 11 = 28
So y changes by 28 - 15 = 13 units
Answer:
![-4x^3+6x^2-x](https://tex.z-dn.net/?f=-4x%5E3%2B6x%5E2-x)
Step-by-step explanation:
1. Distribute the X across the equation: ![-x(4x^2)=-4x^3\\](https://tex.z-dn.net/?f=-x%284x%5E2%29%3D-4x%5E3%5C%5C)
2.![-x(-6x)=6x^2](https://tex.z-dn.net/?f=-x%28-6x%29%3D6x%5E2)
3.![-x(1)=-x](https://tex.z-dn.net/?f=-x%281%29%3D-x)
3.![-4x^3+6x^2-x](https://tex.z-dn.net/?f=-4x%5E3%2B6x%5E2-x)
The answer would be 20 because you have 5 blocks that are cut into 1/4. It doesn't say anything about any of the pieces disappearing or being used yet so you multiply 4*5 and then you get the answer.
55 degrees
The supplementary angle is 55 because 180-125=55
Then subtract the interior angles 180-75-55=55
Answer:
n = 22
Step-by-step explanation:
Since they are vertical angles they are the same.
Therefore you can put together this equation:
2n - 8 = 36
Add 8 to both sides
2n = 44
Divide by 2
n = 22
