Answer: 15 minutes
Step-by-step explanation:
60 / 4 = 15
15 * 3 = 45
45 / 3 = 15
Point slope form is y-y1=m(x-x1)
but first you must get a slope between two points using
insert (-2,-1) and (6,5)
3/4 is your slope, then put this into point slope form
y+1 = 3/4(x +2)
Answer:
-8 < -4
Step-by-step explanation:
<h2>A can complete the work in 7*6 hrs = 42 hrs.
</h2><h2>
</h2><h2>A can complete in 1 hr = 1/42 part.
</h2><h2>
</h2><h2>B can complete the work in 7*8 hr = 56 hrs.
</h2><h2>
</h2><h2>A&B together do in 1 hr = 1/42 + 1/56 = 7/168 = 1/24 part. So they will do in 8 hrs = 8*1/24 = 1/3 part.
</h2><h2>
</h2><h2>Hence they need 1÷1/3 = 3 days to complete the work.</h2>
Answer:
the answer is 5/2 or alternative form 2*1/2 so the answer is C
