Answer:
Part a) The linear model that shows the salesperson’s total income is equal to
Part b) The total income is 
Step-by-step explanation:
Part a)
Let
k-------> the total sales for the year
y-----> the total income for the year
we know that
The linear equation that represent the situation is
Part b) we have
substitute the value of k in the linear model to find the total income
2.1 times 10 = 21 feet
to convert feet into yards you must divide by 3
21/3 = 7 yards
Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20
Pilar must sell 20 items to break even.
Answer:
-6y + 6 = -2(3y - 3)
Step-by-step explanation:
-6y + 6 = -2(3y - 3)
-6y + 6 = -6y + 6
Therefore, the equation has infinitely many solutions.
