I'm assuming you meant to write y=-2x^2-3
There are 2 basic ways to find the vertex.
Since you're in algebra (I'm assuming) plug it into -b/2a. This will give you the x value for the turning point.
-b/2a
0/2(-2)
0
Now plug in 0 to the equation to get the y value.
y=-2(0)^2-3
y=-3
Ok so the point is (0,-3)
Best of luck!
Answer:
reflected over the x-axis, compressed horizontally by a factor of 1/2.
Step-by-step explanation:
y(x) and f(x) means the same.
y = -(2x) means that y(x) was multiplied by -1, and x was replaced by 2x
- -y(x) reflects y(x) across x-axis
- y(a*x) compresses horizontally y(x) by a factor of 1/a. Here, a is 2, then the factor is 1/2.
You started off very well. You identified the given and the pair of congruent sides.
Statement Reason
3. m<POM = m<NMO Alternate Interior Angles
4. m<NOM = m<PMO Alternate Interior Angles
5. ΔPMO ≅ ΔNOM ASA
6. MP ≅ NO CPCTC
Reasoning for statement 3: This is because MN ║PO and MO acts as a transversal.
Reasoning for statement 4: This is because MP ║NO and MO acts as a transversal.
Answer:
I guess 
Step-by-step explanation:
1. rewrite the expression(it helps me tbh)
2. Distribute the positive symbol to (1-3i)
3. treat i as a variable while you combine like terms
4. divide 25 by 6-5i but leave 25/6 as a fraction since it can't be divisible.
