The only coins that alexis has are dimes and quarters. her coins have a total value of $5.80. she
has a total of 40 coins. how many does she have of each coin?

Alexis has 28 dimes and 12 quarters

Step-by-step explanation:

Remember that

Let

x ---->the number of dimes Alexis has

y ---> the number of quarters Alexis has

we know that

-----> equation A

----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using  graphing tool

The solution is the point (28,12)

see the attached figure

therefore

Alexis has 28 dimes and 12 quarters

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

other answer is correct. i had used the radius of the radius somehow. a website:
