The purple line is the axis of symmetry. This is like a mirror. Everything to the left of the line is a mirror image of everything the to right.
The orange curve is the parabola. This is the name of the shape that a quadratic equation forms.
The black dots are the zeroes, x-intercepts, and the roots. These are all terms for the solutions of the graph.
The red dot is the vertex, minimum, and extremum. The vertex is peak of a parabola. Minimum refers to the lowest y-value of a graph, and extremum is a general term for all minima and maxima.
The green dot is the y-intercept. This is where the graph crosses the y-axis.

Answer:
Mean: 11.6
Median: 14
Mode: 18
Range: 17
Step-by-step explanation:
Mean: add all of the numbers and divide by how many numbers there are
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Mode: the number that occurs the most
Range: Subtract the minimum data value from the maximum data value to find the data range. In this case, the datarange is 18−1=17
Answer:
7 benches
Step-by-step explanation:
Ads cost him 450 in 1 month an it costs 100 to make a bench. he then sells that bench for 175 but looses 100 for making it. 75*7 is 525 that breaks it.
Answer:
9x - 13y
Step-by-step explanation:
2(3x - 2y) + 3(x - 3y)
<u>Use distributive law a(b + c) = ab + ac</u>
⇒ 2·3x - 2·2y + 3·x - 3·3y
⇒ 6x - 4y + 3x - 9y
<u>Gather like terms:</u>
⇒ 6x + 3x - 4y - 9y
<u>Combine like terms:</u>
⇒ 9x - 13y
