Answer:
The values of k are all real numbers greater than 3
Step-by-step explanation:
we have

Solve for k
Divide 12 by 3

Divide by 4 both sides


The solution is the interval ------> (3,∞)
All real numbers greater than 3
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
THE CORRET IS THE LETTER C
1)5/24
2)1 and 1/3 im not sure
3)1 and 1/3
4)1/7
