Answer:
x = -6
Step-by-step explanation:
A plot of the points tells you one is above the other on the same vertical line. The equation for a vertical line is ...
x = constant
In order for the line to go through points that have x-coordinates of -6, the constant must be -6. The equation of the line is ...
x = -6
Answer:
(-1,2)
Step-by-step explanation:
The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
Answer:
18x+5
Step-by-step explanation:
Rhe perimeter of a triangle is the sum of its three sides which here are (6x-3), (5x+6), (7x+2).
So we add them all up, 6x-3+5x+6+7x+2=18x+5
Answer:
Part A: 5
Part B: 2
Step-by-step explanation:
to find the mean all you have to do is add all the numbers together and then divide it by how many numbers there are in the data set
3+4+4+4+5+6+6+8=40
40÷8=5
so the mean is 5
next to find the mean of absolute deviations you need to subtract each number in the data set from the mean then divide it by how many numbers are in the data set (if you get a negative like 6-5=-1 just take away the negative sign to make it positive)
5-3=2
5-4=1
5-4=1
5-4=1
5-5=0
6-5=-1
6-5=-1
8-5=-3
2+1+1+1+0+1+1+3=10
10÷5=2
so the mean absolute deviation is 2
