Answer:
![y = 0.5x + 5](https://tex.z-dn.net/?f=y%20%3D%200.5x%20%2B%205)
Step-by-step explanation:
As you can see the value of y increases uniformly with x, so this is a straight line. A straight line follows the formula of
![y = mx + c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20c)
When x=0, y=5, and therefore c=5
![y = mx + 5](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%205)
Use the formula of slope to calculate slope
![m = \frac{5.5 - 5}{1 - 0} \\ m = 0.5](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B5.5%20-%205%7D%7B1%20-%200%7D%20%20%5C%5C%20m%20%3D%200.5)
Hi,
Here are the solutions.
Note that these are numbered in the same manner, and in the same order, as they were posted in.
1. A. 30 degree
15. D. 24 radians per sec square
<span>3. A (Note that answer A should read </span>1/2 ln(sin2x) + c. I am assuming that sin(sx) is a typo in that answer choice. None of the other answers are correct.)
2. D - cos cube 4x/12 + e
3. B. 1/3 e the power of 3x + c
4. A. the anti derivative of 1 + cos10x/2 dx
5. C. u = 2x cube - 4
6. A. sin the power of -1(x + 4)/5 + c
7. C. 1/3 x sin3x + 1/9 cos3x + c
8. C. 1/2 x e the power of 2x - 1/4e the power of 2x + c
9. B. 1/10 e the power of 5x + 1/2 e the power of x + c
10. B. 18 pie
11. B. 5pie/2 + 4
12. B. the square root of 5 pie
13. A. (0, 1.6)
14. A. 7.5(1 + e the power of -2)
<span>15. A. 7.5 the square root of 1 + 4e the power of -2 - e the power of -4

Answer =
B= 50-10t
y-intercept of the function is 50 which represents the charge of the battery when Ashley left her house.
Step-by-step explanation:
|r+3| = (r+3) when r ≥ -3 so for r ≥ -3
r + 3 ≥ 7
r ≥ 4
|r+3| = -(r+3) when r < -3 so for r < -3
-(r + 3) ≥ 7
r + 3 ≤ -7
r ≤ -10
The answer to this question is r ≤ -10, r ≥ 4
