You need to figure out the unit rate so you need to:
1. divide 186 by 23= 8.08695....
2. You only need to figure out the answer to the hundredth of a percent so you would round and get $8.09
3. The answer is $8.09
2(4-d+2d)=12
8-2d+4d=12
8+2d=12
2d=4
d=2
Answer:
y + 1 = 7(x + 2).
Step-by-step explanation:
Point slope form:
y - y1 =m(x - x1).
Here m = 7 and (x1, y1) = (-2, -1)
So the answer is;
y - (-1) = 7(x - (-2))

<h3>
What is the general form of a quadratic equation?</h3>
The general form of the quadratic equation is given by;

Where; a, b, and c are the constants.
x; 0 1 2 3 4 5
y; 2.82 3. 29 3. 46 3. 33 2. 88 2. 24
From the table when the value of x = 0 the value of y is 2.82.
Then,

From the table when the value of x = 3 the value of y is 3.33.

From the table when the value of x = 5 the value of y is 2.24.

And the value of b is;

Therefore,
The quadratic regression equation for this data set is;

Hence, the quadratic regression equation for this data set is
.
