Answer:
Vertex (-2,-9)
zeros: x=1, x=-5
y-intercept: -5
Step-by-step explanation:
When you graph the quadratic equation you obtain the parabola shown in the figure attached.
Find the vertex of the parabola observing the graph, you can that the minimum point of the parabola is at (-2,-9) this is the vertex.
The zeros are the x-intercepts:
x=1; x=-5
And the y-intecept is when x=0 and the parabola cut the y-axis. This is: -5.
In expression form this is:
9 + 2f

Answer:
the answer is d
Step-by-step explanation:
their competing for food so it's either d or c and lions and hyenas are different species so d
Answer:
lines a and b are parallel. The slopes are -1/3
None of the lines are perpendicular to each other.
Step-by-step explanation:
To figure out if any of the lines are parallel or perpendicular to each other, you have to find the slopes of each line. To find the slope look at the graph find the rise over run for all of the lines:
line a: This line goes down one every time it goes over 3, which can be represented by -1/3
line b: This lines goes down one every time it goes over 3, which can also be written as -1/3
line c: This line goes up 5 every time it goes over 2, which makes the slope 5/2
When two lines are parallel, they have the same slope. Line a and line b have the same slope, so they are parallel.
When two lines are perpendicular, their slopes are negative reciprocals of each other. Since none of the slopes are a negative reciprocal of another slope, we have no perpendicular lines.

1/2 of 14 is 7. multiply 14/1 to 1/2.
