Answer:
y = 5x + 3
Step-by-step explanation:
Slope = (13 - 8)/(2-1) = 5
Equation:
y - 8 = 5(x - 1)
y - 8 = 5x - 5
y = 5x - 5 + 8
y = 5x + 3 <-----------the slope-intercept form
Answer:
five billion, seven hundred and eight million, nine hundred and forty two thousand and thirteen
Answer:
(a) $6,412.12
(b) 6624.
Step-by-step explanation:
We have been given the total cost function for a product is , where x is the number of units produced.
(a) To find the total cost of producing 400 units, we will substitute in our given formula.
Therefore, the total cost of producing 400 units is $6,412.12.
(b) To find the number of units produced with total costs of $8500, we will substitute in our given formula.
Switching sides:
Subtract 1900 from both sides:
Now, we will divide both sides of our equation by 750.
Using logarithm definition, we will get:
Therefore, producing 6624 units will give total costs of $8500.
Step 1 is to factor everything!
After factoring you will get:
x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)
Step 2 is to remove the duplicate factors!
Remove x+4 and x+5
x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3
Step 3 is to multiply the numerators and the denominators.
End result is 1 over (x+2)(x-3)
