Answer:
−22.599a−32.513
Step-by-step explanation:
Distribute:
= (4.1) (−7.93) + (4.1) (− 4.39 a) + − 4.6 a
= − 32.513 + − 17.999 a + − 4.6 a
Combine Like Terms:
= −32.513 + − 17.999 a + − 4.6 a
= (− 17.999 a + −4.6 a) + (− 32.513)
= − 22.599 a + (− 32.513) = − 22.599 a − 32.513
<h2>
Answer:</h2>
720 pounds
<h2>
Step-by-step explanation:</h2>
Initially, we have that the amount of algae in the pond is 
. Every four hours the amount of algae doubles. If we called 
the time and 
the amount of algae, we have that:
Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>
Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43
Answer:
h(3) = 73
Step-by-step explanation:
The function 
Now since you need to find the value of this new function at the point x=3, replace x by "3" in the expression above and perform the calculation:
