Answer:
--- Vertex
--- Axis of symmetry
Step-by-step explanation:
Given

Solving (a): The vertex
For an equation written in

The vertex is:

By comparison:
and 

So, the vertex is:

Solving (b): The axis of symmetry
For an equation written in

The axis of symmetry is:
x = h
In (a):

So:

Yo sup??
given line is x=3
this is a line which is parallel to the y axis.
Since it's parallel to the y axis it's slope is infinity.
Hope this helps.
Answer:
perimeter 140
Step-by-step explanation:
60L x 10W = 600
60(2) + 10(2) = 140

Answer:
A box-and-whisker plot is shown above a number line that extends from 70 to 100 with 1 unit markings. The box extends from 79 to between 90 and 91 with a division at 89. There is also a point marked at 89. The whisker on the left extends from 75 to 79. The whisker on the right extends from between 90 and 91 to 93.
i hope this helps u and makes sense :))
