Answer:
18
Step-by-step explanation:
The question is asking you to evaluate -4.5b, which is a simplified way of saying
-4.5 * b
Since we know that b = -4, we can insert that instead of b.
-4.5 * -4
The two negatives cancel each other out, so you're left with
4.5 * 4 = 18
Answer:

y greater than or equal to 14
Step-by-step explanation:
Given the inequality:

We solve it by isolating the variable y on one side. That is, in our case we add 27 to both sides and get:

There is a few ways to get the result.
Lets try this.
First calculate how many minutes are in the 5 hours.
60min*5=300min - in 5 hours
Now, knowing that quarter is 15min we can divide 300 by 15 to get the result, so
300:15=20 - its the result.
From 2000 to 2011, there are 11 years. From the given function, we can calculate the profit for a small business at the end of 2011 by substituting 11 to the x of the given equation.
y = (30,000)(1.06)(11)
y = 349,800
Thus, the profit at the end of 2011 is approximately $349,800.
