Answer:
a)80
b)250
c)130
Step-by-step explanation:
Answer:
One solution is, (3,2)
One solution is, (-1,1)
There are infinitly many solutions
The equation of the line is
Step-by-step explanation:
Anything on the line is a solution.
The line is infinite therefore the solutions are also infinite.
The dot (3,2) and (-1,1) are both on the line therefore they are both solutions.
The slope of the line is 0.25 or 1/4 so we know the first part of the equation.
y = 1/4x
The y-intercept is on the point 1.25 or 5/4
We now know the whole equation
y = 1/4x + 5/4
To double check you can plug in points into the x and y spots on the equation or as I did graph it.
Given:
Number of pen you are to purchase = 240 pens
Number of staplers you are to purchase = 6 staplers
Cost of pen in sets = 6 for $2.35
Cost of stapler in sets = 2 for $12.95
Let's find how much it will cost to purchase these products.
First find the average cost of each item:
To find the total cost, we have the equation:
Total cost = (Average cost of pen x number of pens to be purchased) + (Avg cost of stapler x number of staplers to be purchased)
Let's evaluate the equation:
Solving further:
Therefore, the amount for purchasing these products will cost $132.85
ANSWER:
$132.85
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
