Answer:
the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7
Step-by-step explanation:
When you set two equations or functions equal to each other that is saying you want to know when the graphs intersect. So the y and x intercept don't matter, unless you combined the terms like this.
3x + 5 = 2x – 7
x + 12 = 0 then that terms x intercept woudl be the x coordinate of the intersection of the other two terms. But remember, this is onlyif you combines the two functions.
Of your options you just want the ones dealing with the intersection point. And of those two we are plugging in x, so we want the x coordinate.
Answer:
x ≈ 21.7
I rounded to the nearest tenth because the values are given in tenths. The first few digits of x are below if you are rounding to something else, as the image is cut out.
Step-by-step explanation:
(It will not let me post, so I've attached a screenshot of my explanation:)
To make a box and whisker plot, first you write down all of the numbers from least to greatest.
0, 1, 3, 4, 7, 8, 10
The median is 4, so that’s the middle line of the plot.
So now we have:
0, 1, 3, [4,] 7, 8, 10
So next we have to find the 1st and 3rd interquartiles..
0, [1,] 3, [4,] 7, [8,] 10
Those are the next 2 points you put on the plot.
Lastly, the upper and lower extremes. These are the highest and lowest numbers in the data.
[0,] 1, 3, 4, 7, 8, [10]
These are the final points on the plot.
To make the box of a box-and-whisker plot, you plot the 3 Medians of the data: 1, 4, and 8, and connect those to make a box that has a line in the middle at 4.
Next, you plot the upper and lower extremes: 0 and 10, by making “whiskers” that connect to the box. So you draw a line from the extremes to the box.
Just divide 7 by 6 to convert the fraction to decimal form and then compare the two
