Answer:
The number of nickel's coin is 150
The number of dime's coin is 35
The number of quarter's coin is 75
Step-by-step explanation:
Let
x ----> the number of nickel's coin
y ---> the number of dime's coin
z ---> the number of quarter's coin
Remember that
we know that
----> equation A
----> equation B
----> equation C
substitute equation C in equation A and equation B
---> equation A1
-----> equation B1
Solve the system of equations A1 and B1 by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (75,35)
see the attached figure
so
z=75, y=35
<em>Find the value of x</em>
therefore
The number of nickel's coin is 150
The number of dime's coin is 35
The number of quarter's coin is 75
Answer:
d. Two complex solutions
Step-by-step explanation:
We have been given a trinomial and we are supposed to predict the type of solutions of our given trinomial.
We will use discriminant formula to solve for our given problem.
, where,
,
,
Conclusion from the result of Discriminant are:
Upon substituting our given values in above formula we will get,
Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.
