Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
A polynomial function with all even exponents is so-called even function.
Even functions are symmetric across the y-axis.
Answer: Only one that is symmetric across the x-axis is the function C ).
