Answer:
23.4 units
Step-by-step explanation:
Given the point of the vertices of triangle ABC as A(−5,1), B(2,1), and C(6,4).
The distance (d) between two points X (x₁ , y₁) and Y(x₂, y₂) is given as:
. We can use this to calculate the length of the sides of the triangle. Therefore:

The perimeter of the triangle ABC = AB + AC + BC = 7 + 11.4 + 5 = 23.4 units

Answer:
A) y=4.71x-214.72
Step-by-step explanation:
Using the TI-84 gave me the linear regression
Answer:
Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.
Answer:
The correct options are: Option A, C and D
Step-by-step explanation:
We need to choose correct options by solving the given system of equations.

Let:

First Multiply equation 2 by 2 and add both equations.

Now, we will put value of x in equation 2 to find value of y

So, we get x = 3.14 and y = 2.14
Solution set is (3.14,2.14)
The given solution set (2,3) is not the solution of system of equations.
If we put x=2 and y =3 in the first equation:

(2,3) when substituted in the First equation the equation is True.
If we put x=2 and y =3 in the second equation:

So, (2,3) when substituted in the second equation the equation is false.
The correct options are: Option A, C and D
