Answer:
An equation in slope-intercept form of the line will be
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the points
Finding the slope between (-1,-1) and (1,0)
substituting m = 1/2 and (-1, -1) in the slope-intercept form of the line equation to determine the y-intercept
Add 1/2 to both sides
substituting m = 1/2 and b = -1/2 in the slope-intercept form of the line equation
Therefore, an equation in slope-intercept form of the line will be
Well, this is a stem and leaf problem.
The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42.
In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers).
The mean is 32.
The median is the middle number, or 31.
Answer:
Let's call the width x and the length x + 8. Perimeter can be calculated by multiplying the sum of the length and width by 2 so we can write:
2(x + x + 8) = 80
2(2x + 8) = 80
2x + 8 = 40
2x = 32
x = 16
This means that the length is 16 cm and the width is 24 cm.
