45 degrees, 90 degrees, and 180 degrees. You honestly just gotta rotate them in your mind.

Which expression is positive
Luden [163]
I'm not sure if A B C D are answers, but I can say for sure that C is positive and A, B, and D are negative.

A:
-7*13
Since there is only one -1, the expression is negative;
-7*13=91

B:
14*-2
Here as well, there is only one -1, so the expression is negative;
14*-2=-28

C:
\frac{-14}{-7}
The -1 cancels out;
\frac{14}{7} =2

D:
\frac{-42}{6}
Here, you can't cancel the -1 out, so it remains negative;
\frac{-42}{6} =8

Sorry for the delay, hope this helps :)

How do I find the y coordinates of the vertex of a parabola?
Bess [88]

Answer:

My example:

1. Get the equation in the form y = ax4 + bx + c

2. Calculate -b / 4a. This is the x coordinate of the vertex

3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.

Step-by-step explanation:

y=2x^2 -16x +30

vertex: ( 4, -2)

Focus: (4, -15/8)

Axis of symmetry: x = 4

Directrix: y = -17/8
