Answer:
the correct answer is a because it shows more evidence for itnn
Step-by-step explanation:
and the explanation for this question is that it's really simple and easy.
Answer:
(-3,0) ; (1,0)
Step-by-step explanation:
We have to solve the associated equation:
-2x^2 -4x + 6 = 0
-x^2 - 2x + 3 = 0
x^2 + 2x -3 = 0
Δ/4 = 1 + 3 = 4
x1 = -1 + 2 = 1
x2 = -1 -2 = -3

Answer: f(x) = (-1/2)x+1, choice B</h3>
=================================================
Explanation:
The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).
Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope
slope = rise/run = -1/2
rise = -1, run = 2
The rise being negative means we have gone downhill as we move to the right.
With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1
The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.
I believe the next one would be 13.2 because if you add 8.4 to -6.4 it gets 4.8 so you just do the same thing
