Please help :(( I’ve been stuck on this for like an hour

Lee has $1.75 in dimes and nickels. the number of nickels is 11 more than the number of dimes. how many of each coin does he have?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

What are the interpretations of the line 3x - 15y = 60? x-intercept y-interception a: x 20 - y -4 b: x 5 - y 20 c: x -3 - y 15 d: x -4 - y 20
