Answer:
115 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so if x is the angle you're trying to have you get:

M=n-15
<u>+15 +15</u>
<u>m+15=n
</u><u /><u />So n=m+15
Answer:
4/15
Step-by-step explanation:
convert the 2 fractions to have the same denominator
5/15 and 6/15
together they are 11/15
you have 4/15 left
Answer:

Step-by-step explanation:
Vertex form of a quadratic is given by:

Where (h, k) is the vertex and <em>a</em> is the leading coefficient.
We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:

We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:

Solve for <em>a</em>. Subtract:

Simplify:

Therefore:

Hence, our quadratic is:
