The first thing we must do for this case is to define variables.
 We have then:
 x = the number of nickels
 y = the number of dimes
 z = the number of quarters
 We write the system of equations:
 0.05x + 0.1y + 0.25z = 2.05
 x + y + z = 18
 x = y
 Solving the system we have:
 x = 7
 y = 7
 z = 4
 Answer:
 
nickels = 7
 
dimes = 7
 
quarters = 4

What are the x-intercepts of the graph pf the function below?<br> y=x^2+3x=28
MatroZZZ [7]
To solve this, you need to subtract 28 from both sides, then solve.

y=x^2+3x-28

The x-intercepts are (-7,0) and (4,0)
