Answer:

The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15

and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1

Only A is a function because for the same input value in B, there is two different output values which is not possible.

Step-by-step explanation:

I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.

The y-axis values are the output/range and the x-axis values are the input/domain.

Hope this helps bro

Find an equation of the line that is perpendicular to the graph of 2x+5y=5 and contains the point of intersection of the graphs

gavmur [86]

Answer:

5(x+1) -2(y-3) = 0

Step-by-step explanation:

For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0

In the attached graph, the requested line is shown in black.
