Answer:
x - 3 > = 5
x > = 5 + 3
x > = 8
closed circle on 8...because of the equal sign.....shaded to the right...because of the > sign.
Step-by-step explanation:
Answer:
I think it will be less than 69 because the tozal mean is 41 while of A is 69 mean the values has decreased
2x+y=6
y=6-2x and y=x^2-4x+3
The solution occurs when they are equal so we can say y=y which is:
x^2-4x+3=6-2x add 2x to both sides
x^2-2x+3=6 subtract 6 from both sides
x^2-2x-3=0 factor
(x+1)(x-3)=0
So x=-1 and 3, using y=6-2x we find the corresponding y values...
y(-1)=6--2=8, y(3)=6-6=0 so the two solutions are the points:
(-1,8) and (3,0)
multiply both sides of the equation by 3.
2x+3y=9
move variable to the right side and change its sign
2x=9-3y
divide both sides of the equation by 2
x=9/2-3/2y
