Answer:

The answer to your question is No, it is not a solution

Step-by-step explanation:

Data

Point (4, 2)

                      y = x - 2              Equation l

                      y = 3x + 4            Equation ll

-Solve the system by equality

                    x - 2 = 3x + 4

-Solve for x

                    x - 3x = 4 + 2

                       - 2x = 6

-Result

                           x = 6/-2

                           x = -3

-Find y

                    y = -3 - 2

-Result

                     y = -5      

The solution to this system is (-3, -5), (4,2) is not a solution.

Answer:

False

Step-by-step explanation:

y=x-2  y=3x+4

Substitute the point into both equations and see if it is true

2=4-2

2=2  true

and

2=3*4+4

2 = 12+4

2 =16

False

It is not a solution

Why does a square with an area 20² not have a whole number side length.
Klio2033 [76]

Answer:

This is because the number '20' is not a perfect square.

Step-by-step explanation:

If you find \sqrt{20}, you will be getting 4.4721935955... which is not a whole number, thus 20 is not a perfect square.
