Answer:
y=-1.5
X=1.75
Step-by-step explanation:
Yuh arrange the equations in order for easy subtracting of the equations.
-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.
6x+3y=6
3y=-6x+6 then divide both sides by three to get y
y=-2x+2
now arrange
y=-2x+2
y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x
Answer: m = 2
The formula for slope can be found by finding the difference in y between two values divided by the difference in x between the same two values. In this case, you would subtract 4 from 8 and 2 from 4, to get 4/2, or 2. The slope is represented by the variable m, so m = 2.
To solve this relationship simply make them equal to each other and find the correct value to multiply both the top and cotton numbers and solve,
In this case because of the initial ratio of 1:9, if the bonsai ficus is 6 then 54 inches would be the full size.
X = 8. You can find this by adding 90 (from the shown 90 angle to 18 and then subtracting 180-102 = 9x to since angle LJW is known to be 180 degrees (since its a straight line). Solving we get 72 = 9x.
Divide both sides by 9
X = 8
I hope this helps!
Answer:
Step-by-step explanation:
As the mean is 20.2 and the standard deviation is 2.4
The range within the first standard deviation is
(17.8,22.6)
This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.
Within this range there are
