21,985,233 to the millions place is 22,000,000
Answer:
In order down the left side, ...
- y = 1/3x +2
- y = 1/2x +3
- y = 2x +6
- y = -2x +3
Step-by-step explanation:
To put a linear equation in slope-intercept form, you solve for y, then simplify.
<u>x -3y = -6</u>
Subtract x and divide by -3:
y = 1/3x +2
__
<u>2y -6 = x</u>
Add 6 and divide by 2:
y = 1/2x +3
__
<u>-x +(1/2)y = 3</u>
Add x and multiply by 2:
y = 2x +6
__
<u>2x +y = 3</u>
Subtract 2x:
y = -2x +3

<em>Comment on the algebra</em>
Note that when we say add, subtract, multiply, or divide by something or other, we mean to <em>do that to both sides of the equation</em>. That is required by the properties of equality.
If you remember the rule: do the same thing to both sides of the equation, then algebra suddenly becomes much easier.
I'm gonna say the average is 1.5 because is the sum of the elements divided by the number of elements.
0+1+3+2=6
6/4= 1.5
