Which of the following points is a solution of the system shown below y=x+7
y=11-x
(1) (5, 12)
(2) (2, 9)
(3) (1, 10)
(4) (-4, 7)

The correct answer is (5,12)

y= x +7

12=5 +7

12=12

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
