Answer:
10.50x+11.90y=178.50
Step-by-step explanation:
x = represent the number of hours worked stocking shelves
y= represent the number of hours worked in sales.
You earn $11.90 per hour as a salesperson = 11.90y.
You earn $10.50 per hour stocking shelves =10.50x.
Your combined earnings this month are $178.50.
10.50x+11.90y=178.50
The required equation model the situation is 10.50x+11.90y=178.50
Answer:
Step-by-step explanation:
The integral from a to 4 is ...
We want the value of this to be 12, so we can write ...
-3/2a^2 +a +20 = 12
3a^2 -2a -16 = 0 . . . . . subtract the left side and multiply by 2
(3a -8)(a +2) = 0 . . . . . factor
a = 8/3 or -2 . . . . . . . .values of a that make the factors zero
The only possible values of a are 8/3 and -2.
Answer:
or
Step-by-step explanation:
we have
This is a vertical parabola open upward (because the leading coefficient is positive)
The vertex is a minimum
Convert to vertex form
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
or
The vertex is the point (0.25,10.5)
