Answer:
x=4 and y=5
Step-by-step explanation:
The given system of equations are
The matrix form is
Let as assume
then,
We know that,
Therefore, the value of x is 4 and value of y is 5.
To find the range of any type of data you have to take the largest and smallest number and subtract those numbers then when that is done you have your answer
g(1)=2(1)-3 = -1
f(g(1))=f(-1) = 5(-1) = -5
Second choice
Answer:
9/2
Step-by-step explanation:
(a) Dividing by a fraction is the same as multiplying by its inverse.
(1 1/2)/(1/3) = (3/2)/(1/3) = (3/2)(3/1) = 9/2
The quotient is 9/2 = 4.5.

(b) If you have 1 1/2 pounds of nuts, how many bags can you fill such that each bag is 1/3 pound of nuts?
answer: 4 1/2 bags. That is 4 bags with 1/3 pound, and the 5th bag half full.
Answer:
The indifference point is 500 calls.
Step-by-step explanation:
Giving the following information:
Plan 1 charges $32 per month for unlimited calls and Plan 2 charges $17 per month plus $0.03 per call.
I assume we have to determine the indifference point between the two plans.
<u>First, we need to structure the cost formulas:</u>
Plan 1= 32
Plan 2= 17 + 0.03*x
x= call
<u>Now, we need to equal both formulas:</u>
32 = 17 + 0.03x
15= 0.03x
500= x
The indifference point is 500 calls.
Plan 1= $32
Plan 2= 17 + 0.03*500= $32
