Use the formula for average rate of change over an interval of two points:

We have two points: (-2, -1) and (0, -1). Plug the values into the formula:

The average rate of change over the interval [-2,0] is
0.
X + 3 * 21 = 12
x + 63 = 12
x = 12-63
x = -51
The wording was a little odd, but I hope this is what you’re looking for!
Answer:

Step-by-step explanation:
The computation of the area of kite ABCD is shown below:
Given data
AC = 10 ;
BD = 6
As we can see from the attached figure that the Kite is a quadrilateral as it involves two adjacent sides i.e to be equal
Now the area of quadrilateral when the diagonals are given
So, it is

where,

So, the area of the quadrilateral is

Answer:
Law of Sines
Step-by-step explanation:
Law of Sines: 
Step 1: Solve for m∠B

25sinx = 27sin36°
sinx = 27sin36°/25

m∠B ≈ 39.4°
Step 3: Find m∠C
180 - (36 + 39.4)
180 - 75.4
m∠C = 104.6°
y + 2=-3(x - 7)
