2 answers:
Answer:
Step-by-step explanation:
A <em>product</em> of two numbers is the result we get from multiplying them together. The product of 4 and x would then be , which we can rewrite as
. We're then told by the statement "one minus the product..." that we'll be taking this
away from 1, giving us the answer

Answer:
$12500
Step-by-step explanation:
Given that:
Salary plan 1:
Weekly salary of $500.
And a commission of 4%.
Salary plan 2:
Straight commission of 8%.
To find:
Weekly sales for which both the plans will make the same sales?
Solution:
Let the weekly sales = $
As per question statement:
Salary as per Plan 1 = $500 + 4% of
Salary as per Plan 2 = 8% of
Putting both the salaries to equal to find the total weekly sales.
$500 + 4% of = 8% of
Therefore, the answer is:
For the sales of $12500, the salary will be same from both the plans.
Answer:
D. Minimum at (3, 7)
Step-by-step explanation:
We can add and subtract the square of half the x-coefficient:
y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2
y = (x -3)^2 +7 . . . . . simplify to vertex form
Comparing this to the vertex for for vertex (h, k) ...
y = (x -h)^2 +k
We find the vertex to be ...
(3, 7) . . . . vertex
The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.
