(2,0)

the first # is the x coordinate which is left and right. Since B is 2 to the right from the center (0,0) x is 2. Left would make it negative
The second # is the y coordinate which is up and down. Since B is on the x axis the y coordinate is 0.

Please help!! also please explain I would like to understand.​
ziro4ka [17]

Answer:

A

Step-by-step explanation:

First, put this equation in slope intercept form.

y=mx+b

Where m is the slope and b is the y intercept.

y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point (2,1) is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.

If f(x)=2x and g(x)=x+5, then g(f(x))= <br><br> A) 2x+5<br> B) 2x+10
Natali [406]

Answer:

A. 2x+5

Step-by-step explanation:

You can solve these by substituting f(x) as the input (or x value) in g(f(x)). This would be putting the 2x in as the "x" in x+5. So 2x+5.

Alexander and Jo live 5 miles apart. They decide to leave their homes at 3 p.M. And travel toward each other. If Alexander bikes
lukranit [14]

Answer:

Step-by-step explanation:

Here is an illustration of the problem:

             ----------------------------->|<------------------

            A                                  t                     J

Alex and Jo start from their separate homes and drive towards one another.  The t indicates the time at which they meet, which is the same time for both.  Filling in a d = rt table:

              d           =        r        x        t

Alex                              14                t

Jo                                   6                t

The formula for motion is d = rt, so that means that Alex's distance is 14t and Jo's distance is 6t.

             

                      14t                               6t

   ---------------------------------->|<------------------

   A                                       t                      J

The distance between them is 5 miles, so that means that Alex's distance plus Jo's distance equals 5 miles.  In equation form:

14t + 6t = 5 and

20t = 5 so

t = .25 hours or 15 minutes.

If they leave their homes at 3 and they meet 15 minutes later, then they meet at 3:15.
