Answer:
(-5,-37)
Step-by-step explanation:
While the standard quadratic form is a x 2 + b x + c = y , the vertex form of a quadratic equation is y = a ( x − h ) 2 + k . In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you whether the parabola is facing up ( + a ) or down ( − a ).
We solve X simultenously
x - 2y =2................equation 1
3x - 5y =9.............equation 2
find urself third equation frm dis two equations
x = 2+2y...........equation 3
SUB: 3 IN 2
3(2+2y)-5y =9
solve y
6+6y-5y=9
6y-5y=9-6
1y=3
divide both side by 1
therefore Y=3
SUB:Y=3 IN EQUATION 3
x=2+2(3)
x=8

Answer:
Step-by-step explanation:
Refer to the attached figure. Note that the solution set is shaded, and includes all points on the solid boundary line.
black point (-1,1) is outside of the solution set
Red point (1,-1) is also outside of the solution set.
Yellow point (3,2) is on the solid boundary line, so it is part of the solution set
Blue point (2,3) is outside of the solution set.
