Answer:
56 dived by 4. answer would be 14. so she would need to run two weeks
Step-by-step explanation:
Answer:
<u>Slope = 3</u>
Step-by-step explanation:
The slope is the Rise/Run
Given the two points (-1,-4) and (2,5) we can calculate both the Rise and the Run:
Rise = (5 - (-4)) = 9
Run = (2 - (-1)) = 3
Slope is Rise/Run
(9/30) = 3
It is the "m" in y = mx + b
The actual equation is y = 3x + 1. Use one of the 2 points and solve for b to find that it equals -1.
y = 3x - 1 for (2,5)
5 = 3(2) - 1 ?
5 = 5 Yes
Let...
l=length
w=width
Because we know that the perimeter is 90, we can make this equation...
2l+2w=90
Because we know that the length is 5 feet less than 4 times the width, we can make this equation...
l=4w-5
We can solve this system through substitution...
2(4w-5)+2w=90
8w-10+2w=90
10w=100
w=10 ft
l=4(10)-5=35 ft
Answer:
1.) The slope of an equation expressed in the form of y= mx+b is m.
