The answer is 3
Multiply 6 by 3 to get the total amount of money for the books then minus the answer 18 which you get from 6 x 3 = 18
Then minus 18 from 21 to get $3
21 - 18 = 3
Step-by-step explanation:

Answer:
x=0
Step-by-step explanation: If x=0, then two points on the graph can be (0, 6) and (0,0). using those two points, you can say the slope is 6/0, which is undefined
Answer:
the last answer is -1 :))))))
To answer, subtract x² from both sides of the equation to give us,
y² = -x² + 9
Then, we derive the equation in terms t.
2y(dy/dt) = -2x(dx/dt)
Substituting the known values from the given,
2(sqrt6)(dy/dt) = -2(-sqrt3)(20)
The value of dy/dt is 14.14.
