Answer:

a. Substitute 0 for x and solve for y

b. Substitute 0 for y and solve for x

Step-by-step explanation:

Getting the zeros of the given equation is similar to finding the x-intercept and y-intercept of the equation

The x intercept occurs where y = 0

Substituting y = 0 into the expression and getting x we have;

9x + 2y = 18

9x +2(0)= 18

9x = 18

x = 18/9

x=2

Hence the x intercept is 2

Similarly, to get the y intercept, we will substitute x = 0 and get the value of x a shown:

When x =0.

9(0)+2y = 18

0+2y = 18

2y= 18

y = 18/2

y = 9

Hence the zeros of the equations occurs at (2, 9)

The correct options are

-Substitute 0 for x and solve for y

-Substitute 0 for y and solve for x

A. Every month Population will increase by a factor of 0.84%.

B.  Every 3 months Population will increase by a factor of 2.5%.

C. Increase in population in every 20 months is 10% + 6.72% = 16.72%.

<u>Step-by-step explanation:</u>

Here, we have  number of employees in a company has been growing exponentially by 10% each year. So , If we have population as x in year 2019 , an increase of 10% in population in 2020 as  x + \frac{x}{100}\times10 which is equivalent to \frac{11x}{10}.

<u>A.</u>

For each month: We have 12 months in a year and so, distributing 10% in 12 months would be like \frac{10}{12}  = 0.84 . ∴ Every month Population will increase by a factor of 0.84%.

<u>B.</u>

In every 3 months: We have , 12 months in a year , in order to check for every 3 months  \frac{12}{3} = 4 and Now, Population increase in every 3 months is \frac{10}{4}  = 2.5.  ∴ Every 3 months Population will increase by a factor of 2.5%.

<u>C.</u>

In every 20 months: We have , 12 months in a year in which increase in population is 10% . Left number of moths for which we have to calculate factor of increase in population is 20-12 = 8. For 1 month , there is 0.84% increase in population ∴ For 8 months , 8 × 0.84 = 6.72 %.

So , increase in population in every 20 months is 10% + 6.72% = 16.72%.
