A bag contains 23 coins consisting of quarters and dimes. The total value of the coins is $3.65. Which system of equations can be used to determine the number of quarters, 4, and the number of dimes, d, in the bag? A.0.10q+0.25d = 3.65 O
q+ d = 23
B.0.10q+0.25d = 23
q+ d = 3.65
C.0.25q+0.10d = 3.65
q+ d =23
D.0.25q+ 0.10d = 23
q+d = 365

I think it is equation D.  hope this helped

Step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
