Answer:
1.25 pages per minute
Step-by-step explanation:
If Sydney read 50 pages at a constant rate in 40 minutes, then to get pages per minute just divide total pages by minutes
3X-8=-4X+6 7X-8=6 7X=14 X=14\7=2
In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.
y = mx + b
y = 2x + 15
slope(m) = 2 and y int (b) = 15
The initial amount is the y intercept, which is 15. The rate of change (the slope) is 2
example :
baskets picked in 1 hr :
y = 2(1) + 15
y = 2 + 15
y = 17
baskets picked in 2 hrs :
y = 2(2) + 15
y = 4 + 15
y = 19
so the slope ( rate of change) is basically saying for every hr of picking, you pick 2 baskets...so your picking 2 baskets per hr.
The y intercept (15) is telling us that they already had 15 baskets to start with.
A = 1/2bh
40 = 1/2 x^2
x^2 = 80
x = 8.9
Answer:
(600 miles) / (3 hours) = 200 miles/hour
= 321.8 km/h
