Answer:
17550 solutions
Step-by-step explanation:
Given that:
y1 +y2+y3+y4=27
where;
(yi ≥ 0 and yi
)
The no. of a nonnegative integer determines the number of ways to choose 27 objects from (4) distinct objects with repetition regardless of the order.
i.e
∴
The number of nonnegative integer solution is
= 17550 solutions
Question:
Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Select all that apply.
(3.6,0.6)
(-2.6,0.4)
(-3.6,0.6)
(2.6,0.4)
(4.5,-1.5)
Answer:
Option A : is the solution to the system of equations.
Option D: is the solution to the system of equations.
Explanation:
The two equations are and
To determine the solution of the system of equations using technology, let us plot the equations in the graphing calculator.
The solution of the system of equations is the intersection of the two lines.
Thus, from the graph, we can see that the two lines f(x) and g(x) intersect at the points and
Rounding off the solution to the nearest tenth, we get,
and
Thus, the solution to the system of equations is and
Hence, Option A and Option D are the correct answers.
