The values of x are 4, -4, and -2.

We can solve this by simply factorising the (x² - 16) bracket into a difference of two squares, to give us (x + 4)(x - 4), and then setting each bracket equal to 0.

When x + 2 = 0, x = -2

When x + 4 = 0, x = -4

When x - 4 = 0, x = 4

I hope this helps!

The population of an Asian country is growing at the rate of 0.7% annually. If there were 3,942.000 residents in the city in 199

Anettt [7]

Answer:

b) 4,000,000

Step-by-step explanation:

Let the population is measured since 1995,

Given,

The initial population, P = 3,942,000,

Annual rate of growing, r = 0.7% = 0.007,

If y represents the population after t years

So, the population after t years would be,

$y=Pe^{rt}$

$y=3942000(2.7)^{0.007x}$

Therefore, the population after 5 years,

$y=3942000(2.7)^{0.007\times 5}=3942000(2.7)^{0.035}=4081448.78924\approx 4000000$

Hence, the population in 2000 would be approximately 40,00,000.

Option 'b' is correct.

I think the answer is B.
6(-3)=-18, and y=2
so 6x-y=-18-2=-20
