Answer:
7/4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
take 2 pointes in your graph, i took: (-1,-3); (3.4)
(-1,-3)as (x1,y1). (3,4) as (x2,y2)
So,
m=(4-(-3))/(3-(-1))
m=7/4
that's your slope.
You can try the ac method.
1. Try to factor a common factor from all terms.
2. Multiply ac.
3. Find two factors of ac that add to b, call them p and q.
4. Rewrite the trinomial with the bx term broken up into into px + qx.
5. Factor by grouping.
Answer:
1/20
Step-by-step explanation:
1/5 chance she will wear the blue shirt on the first day and 1/4 chance she will wear a grey shirt on the second day.
1/5 X 1/4 = 1/20
The highest common factor of 5, 3, and 4 is 60, so therefore the lights will flash at the same time after 60 seconds.
