Answer:
The answer is 18. Coz 2*9= 18
It should be y1 - y2/x1 - x2 this is supposed to be a fraction
I end up getting -31 - 24/5 + 6 or -31 -24/5 - (-6)
to see quick score she must use a pie chart
<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
All are correct except these 2:
The graph has one x-intercept:
No, the graph does not cut at the x-axis at all, there is no x-intercept.
The graph as a y-intercept at (5,0):
No, the y-intercept is at (0,5)
