Answer:
Slope= m = Δy/Δx = (y₂-y₁)/(x₂-x₁) = rise / run
Step-by-step explanation:
Hope that helps . Just plug in your values if you are given two points
for example: (3,4) = (x₂,y₂) (1,2) = (x₁,y₁)
Just substitute in the equation above
(4-2)/(3-1) = 2/2 =1
good luck
Answer:
a. about 15.51 miles, rounded to 15.5 miles
b. about 31.02 miles, rounded to 31 miles
Step-by-step explanation:
Sunday Monday Tuesday Wednesday Thursday Friday Saturday
10 20 40 80 160 320 640
1280 2560 5120 10240 20480 40960 81920
81920/5280 = 15.51515151, rounded to the nearest tenth of a mile, 15.5 miles
Question b asks for how many miles in total has he ran. That means we have to add each of the values shown above and that equals to 163830 feet.
Divide that by 5280 and that equals 31.02 miles, rounded to the nearest tenth, 31 miles.
First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.
3=4=7
Next, you divide this amount into your total amount of cans of soda.
28/7=4.
This means that for each one in the ratio, there is 4 cans. So you multiply both numbers in the ratio by 4.
3*4 = 12
4*4=16
So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.
Answer:
A. n = 5
Step-by-step explanation:
S = n² + n
When S = 30:
n² + n = 30
Subtract 30 from both sides: n² + n - 30 = 0
Factorize: (n - 5)(n + 6) = 0
Therefore n = 5 or -6
As n > 2, then n = 5 only
