Is (4,10) a solution to this system of equations? y=2x+2 y=10x+1
vladimir1956 [14]

Answer:

No

Step-by-step explanation:

To find out if (4,10) is a solution to the system, we plug in the values of x and y into each equation.

1:

  • 10=2(4)+2
  • 10=8+2
  • 10=10  

2:

  • 10=10(4)+1
  • 10=40+1
  • 10\neq 41

As you can see, (4,10) only satisfies ONE equation, not both. Therefore, the answer is no, it's not a solution.

The first line in a system of linear equations has a slope of 3 and passes through the point (-1 , -8). The second line passes t
gregori [183]
The equation of the first line can be written in point-slope form as
.. y = 3(x +1) -8
or
.. 3x -y = 5

The equation of the second line can be written in 2-point form as
.. y = (-1-3)/(10-(-6))*(x +6) +3
.. y = (-1/4)(x +6) +3
or
.. x +4y = 6

A graph shows the solution to this system is (x, y) = (2, 1).

_____
The second equation can be used to write an expression for x:
.. x = 6 -4y
This can be substituted into the first equation.
.. 3(6 -4y) -y = 5
.. 18 -13y = 5 . . . . . . . collect terms
.. 13 = 13y . . . . . . . . . add 13y-5
.. 1 = y . . . . . . . . . . . . divide by 13
From the above equation for x
.. x = 6 -4*1 = 2
