A). Y = 3x - 2
B). Y = 2/3x + 11/3
;)
Answer:
When they are equal, y=y, so we can say:
x^2+5x-2=x+1 subtract x from both side
x^2+4x-2=1 add 2 to both sides
x^2+4x=3, now add half the linear coefficient squared, (4/2)^2=4
x^2+4x+4=3+4 now the left side is a perfect square
(x+2)^2=7 now take the square root of both sides
x+2=±√7 subtract 2 from both sides
x=-2±√7
x=-2+√7 and -2-√7
y=x+1 the two points where these equations are equal are:
(-2-√7, -1-√7) and (-2+√7, -1+√7)
or approximately:
(-4.65, -3.65) and (0.65, 1.65)

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.
Each edge measures approximately 0.465 inches
