Answer:
1
Step-by-step explanation:
x+y=1 if x=0, then y=1
The slope is always change in y value over change in x value so if you pick any 2 points on the line you’ll see that the slope is 30/40 and that simplified is 3/4 so the slop is 3/4
I think the answer is (-8,-26)
The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.
The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.
2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.
2/7 = x/10
cross multiply:
10 * 2 = 20
7 * x = 7x
7x = 20
x = 2.857
