Answer:

Step-by-step explanation:
<u>Vertex form of a quadratic equation</u>:

where:
- (h, k) is the vertex
- a is some constant
<u>Given vertex</u>: (2, -6)
⇒ h = 2 and k = -6
Substitute the values of h and k into the formula:


As we have not been given a value for the constant
, assume this is 1.
Therefore, the <u>vertex form</u> of the <u>quadratic function</u> with vertex (2, -6) is:

Answer:
18 =y
Step-by-step explanation:
56=38+y
Subtract 38 from each side
56-38=38-38+y
18 = y
The answer to your question is -32.9
Let us assume number of points scored by Team B = b points.
Number of points scored by Team A 5 fewer than twice as many points as Team B, that is "5 less than 2b" = (2b-5) points .
Team C scored 80 more points than Team B, that is " 80 more than b" = (b+80) points.
Total number of points scored by all teams = 983 points.
Therefore, we can setup an equation:
<h3>(2b-5) + b + (b+80) = 983.</h3>
Therefore, an equation to represent this scenario using the variable b to represent Team B’s total points is (2b-5) + b + (b+80) = 983.
Cut the three lines off center enough so that when they intersect they form a seventh piece in the center of the circle. I hope this is clear enough. If it's not, tell me and I'll try to elaborate further.
