Hey,
The x-intercepts are the coordinates where the line intercepts the x-axis.

Answer:
(-1, 6)
Step-by-step explanation:
A graphing calculator shows the vertex to be (x, y) = (-1, 6).
__
You can also find it by putting the equation into vertex form.
y = -2(x^2 +2x) +4
y = -2(x^2 +2x +1) +4 +2(1) . . . . . add 1 inside parens; the opposite outside
y = -2(x +1)^2 +6
Compare to ...
y = a(x -h)^2 +k
and you see a=-2, h=-1, k=6
The vertex is (h, k) = (-1, 6).
When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.
Answer: graph it ?
Step-by-step explanation:
Ratios are basically a number v a number. Like if your in a group of 30 people and 10 of them are boys, your ratio of girls to boys would be 20:10. That's like really really basic ratio and idk how advanced in rations you are but yeah.
