Write the equation like this: 275 + 55h = 440. Then, subtract 275 on both sides making the left side cancel out and the right side 165. Lastly, divide 55 on both sides to get h all by itself. The solution is h = 3. You must drive 3 hours longer to reach your destination.
Answer:
5 < x < 21
Step-by-step explanation:
The sum of the shorter sides is greater than the longest side.
If 13 is the longest side:
x + 8 > 13
x > 5
If x is the longest side:
8 + 13 > x
21 > x
Therefore, the third side is any number between 5 and 21.
First of all we can rule out that the slope is 10. The coefficient before the x term is not 10 so the answer is not a.
Following on what I said for option a, option b is correct as the coefficient before the x term is -7/8. Therefore the answer is B.
The answer is not C as when x = 0, y is not 0. This means the line does not pass through the origin (0,0)
Option D is not true aswell. When x = 1, y= 9.125. When x= 2, y= 8.25. When x=3, y= 7.375. X is increasing whereas y is decreasing. Therefore option D is ruled out.
The answer is option B.
I hope this has helped you.

Answer:
o.42
Step-by-step explanation:
The values based on the calculus computed will be 10✓5, 10✓1, and 20.
<h3>How to calculate the value?</h3>
dy/dt = 5 units.
Differentiate with respect to t.
dx/dt = 1/2✓x dx/dt
dyldt = 5.
dx/dt = 2✓x × 5 = 10✓x
a. When x = 1/5
dx/dt = 10 × ✓1/5 = 10✓5
b. x = 1
Differentiate it
dx/dt = 10✓1
c. x = 4
dx/dt = 10✓4 = 20
