Answer:
B
Step-by-step explanation:
Hey There!
To solve this problem we have to combine like terms
![7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2](https://tex.z-dn.net/?f=7x%5E3-6x%5E3%3Dx%5E3%5C%5C6x%5E2-8x%5E2%3D-2x%5E2%5C%5C-5x%2B10x%3D5x%5C%5C5-7%3D-2)
So our answer would be
(b)
15 1/3 - 6 1/4 - 4 2/3 = <span>4.41666666667 hours</span>
Remembering that "slope" signifies "rise" over "run," read off the rise and run from the illustration. If we start at x=-4 and move to the right 4 units, x becomes 0. The "run" is thus 4. At the same time, y increases from 0 to 2, and so the "rise" is 2.
The slope is rise/run = 2/4 = 1/2.
The y-intercept can also be read off the graph: Find the y-value on the x-axis where the graph (the sloping line) crosses the y-axis. It's 2.
Thus, the equation of this line is y = mx + b, or y = (1/2)x + 2.
