Answer:
y=17
Step-by-step explanation:
So the shape is a square, which means 1 is equal to 90 degrees. So, 4y+22=90
When you solve, you get 17:
4y=68
y=17
Answer:

Step-by-step explanation:
We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is
where we substitute a point (x,y) for
.
We have m=-3/4 and (-8, 7). We input m and
.

We now simplify the parenthesis and solve for y.

We convert 8 into a fraction with 1 as the denoinator.

We add 7 to both sides to isolate y,

This is slope intercept form. The line as slope -3/4 and y-intercept (0,1) or b=1.
I think that it is median since the 5 scores are so close together and the 6th is an outlier (freaky high)
Answer: 
Step-by-step explanation:
For this exercise it is important to remember that:
1. The Addition property of equality states that:
If
, then 
2. The Subtraction property of equality states the following:
If
, then 
3. The Division property of equality states that:
If
, then 
4. The Multiplication property of equality states the following:
If
, then 
Then, having the following equation given in the exercise:

You need to solve for the variable "r" in order to find its value.
In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.
Therefore, you get the following solution:
