Substract 6 to both sides and you get 36 =-2d then you use the multiplicative inverse and d=-18.
For this case we propose a system of equations. We have to:
x: Let the variable that represents the number of dimes
y: Let the variable that represents the number of quaters
We know that:
One dime equals 10 cents, $0.10
A quater equals 0.25 cents, $0.25
According to the statement we have:
We multiply the first equation by -0.10:
We have the following equivalent system:
We add the equations:
Approximately 3 quater coins
And two dimes
Answer:
3 quater
2 dimes
(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
Answer:
x = 48.125
