Step-by-step explanation:
![\longmapsto \rm \dfrac{6m + 7}{3m + 2} = \dfrac{5}{4}](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5Crm%20%5Cdfrac%7B6m%20%2B%207%7D%7B3m%20%2B%202%7D%20%3D%20%5Cdfrac%7B5%7D%7B4%7D%20)
By cross multiplication,
→ 4(6m + 7) = 5(3m + 2)
→ 24m + 28 = 15m + 10
→ 24m - 15m = 10 - 28
→ 9m = -18
→ m = -18 ÷ 9
→ m = -2

Your ans is 1
please tell me if this is correct.
Answer:
x= -1/21
Step-by-step explanation:
21x + 11 - 5 = 5
21x + 6 = 5
(-6 each side)
21x = -1
(divide 21 each side)
x= -1/21
Answer:
Graph it on a graphing calculator
Step-by-step explanation:
The average rate of change in h(t) between t = 1 second and t = 3 is:
(h(3) - h(1))/(3 - 1) = ((3 + 70*3 - 16*3^2) - (3 + 70*1 - 16*1^2))/2 = 6
The average rate of change in h(t) between t=1 and t=3 tells us that that average speed between these points is 6 ft/s.
