I know the answer, it is -1.
i. 5x ≥ -12 (It can be solved similarly to an equality)
5x/5 ≥ -12/5
x ≥ -12/5
The number line looks along the lines of
<---------l-------------> (filled circle)
-12/5
ii. The smallest integer that satisfies x ≥ -12/5 is -2 because -12/5 = -2.4.
Answer:
A. 6x^{2}+6y^{2}=144
Step-by-step explanation:
Answer:
Step-by-step explanation:
So the initial value of the business computer is $20,000. It depreciates by 15% per year. This is exponential decay. The standard function for exponential decay is:
Where <em>P </em>is the initial value, <em>r</em> is the rate of decay, and <em>t</em> is the time in years.
Since the computer decreases by 15% per year, this means that each year, the computer will be 1-15% or 85% than its previous value.
Therefore, the equation that models the value of the computer is:
Answer:
150 red bars
Step-by-step explanation:
To solve this, you can use proportions. First, set up your two ratios (4:3 is equal to 200:___). Each ration represents the number of green bars to red bars. To get from 4 to 200, you can multiply 4 by 50. You could do the same to 3. 3 times 50 is 150, so there are 150 red bars.
