Answer:
y($) = 405- 20x
Step-by-step explanation:
Number of short driveways = x
Number of long driveways = 9-x
Fee per long driveway = $45
Fee per short driveway= $25
Total amount = y
y ($) = 25x + 45 (9-x)
= 25x + 405 -45x
= 405- 20x
I think the correct answer from the choices listed above is option D. The function that will produce the same graph as the function y=(x+1)(x-3) would be <span>y=x^2-2x-3. Both equations are the same. You can confirm it by simplifying the equation. Hope this answers the question.</span>
Answer:
a. 1/10 or 10%
b. 1/2 or 50%
Step-by-step explanation:
Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.
If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.
Here is the method for solving that equation:
Step #1: Write the equation:
-15x = 0
Step #2: Divide each side of the equation by -15 :
<u>x = 0</u>
