X= (3,0), (1,0)
Y= (0,3)
That's all I know for you.

Intercepts:
x-intercept=1,3
y-intercept=-3

Axis of symmetry equation: x=2 (this basically just represents a vertical line going straight up and down and crossing the x-axis at 2)

Find the interquartile range of the data.

likoan [24]

The answer is 14. Here is how I work it out.

First we are going have to identify quartile 1 and quartile 3.

So after putting the numbers in order from least to greatest mark the number with a half way point.

This is optional but it will help us spot the sections better.

31,33,35,41,43,|46,48,49,49,50

Next put parentheses around the remaining groups of numbers.

(31,33,35,41,43,)|(46,48,49,49,50)

For the next step we have to find the median of each group.

(31,33,35,41,43,)|(46,48,49,49,50)

The median of each group, are called the quartiles, the median of the lower half is quartile 1, and the median of the upper half is quartile 3.

Now subtract quartile 1 from quartile 3.

49 – 35 = 14

So the interquartile range of this data set is 14.

Can someone please help me figure out how to find b in these equations for perpendicular lines also it's do tomorrow so it would

Kamila [148]

To find b you would be using the equation y=mx+b so to find be simply look at your equation and put your numbers in place so the answers so you would put your answers for the first one y=(m=-2)x(b=-3)
so easily the answers to these would be a=-3, b=-3 ,c=-4 ,d=-2
have a good night but definitly remeber the formula i told you for a test
