Answer:
Statements A and D
Step-by-step explanation:
A. Since all of the values surrounding x = 0.5 reflect across that point, there is a line of symmetry at x = 0.5
B. This is not a y intercept since in the point (-12,0) the x value is not zero and at y intercepts, it should be zero.
C. Same thing from statement B, the y value for the x intercepys should be zero, not 4 or -3.
D. To help visualize this, take the slope of the secant line from x = -4 to x = 0.
(8 - (-10))/(-4 - 0) = 18/(-4) or -9/2. Since the slop is negative, the function is decreasing on this interval.
Given that
5! Is 5x4x3x2x1, and 2! Is 2x1, when dividing 5! By 2!, it remains 5x4x3=60 when simplifying 2x1 in both numerator and denominator
In order to check a solution, just plug in the coordinates. The 1 is x, and the -1 is the y. Just plug the numbers in and see if it works out:
y = 3x + 2
(-1) = 3(1) + 2
-1 = 5
-1 is NOT equal to 5, so (1, -1) is NOT a solution of y = 3x + 2.
