What is the solution to –2(8x – 4) < 2x + 5?

RSB [31]

Simplify both sides of the inequality.

−16x+8<2x+5

Subtract 2x from both sides.

−16x+8−2x<2x+5−2x

−18x+8<5

Subtract 8 from both sides.

−18x+8−8<5−8

−18x<−3

Divide both sides by -18.

−18x/−18 < −3/−18

x>16

Ans : x > 16

an insect population grows at a rate of 25% per year.if its initial population is 4.2 million what will be its population in thr

marusya05 [52]

The population after 3 years would be 8.20 millions.

Step-by-step explanation:

Given,

Initial population = I = 4.2 million

Growing rate = r = 25%

If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:

$x = I * (1 + \frac{r}{100} )^{n}$

By putting the values in the equation, we get

$x = 4.2 * (1 + \frac{25}{100} )^{n}$

The population after 1st year (x1) would be

$x1 = 4.2 * (1 + \frac{25}{100} )^{1}$

x1 = 5.25 million

Similarly,

$x2 = 4.2 * (1 + \frac{25}{100} )^{2}$

x2 = 6.56 million

$x3 = 4.2 * (1 + \frac{25}{100} )^{3}$

x3 = 8.20 million

Hence, the population after 3 years would be 8.20 millions.

But, if you are asking about the total population at that time. It would be

I + x1 + x2 + x3 = 24.21 million

What is the equation of the line in slope intercept form

slavikrds [6]

Answer:

y = 4/3x +4

Step-by-step explanation:

The first step is to find the slope

We have two points (-3,0) and (0,4)

m = (y2-y1)/(x2-x1)

= (4-0)/(0--3)

= 4/(0+3)

=4/3

Then we need the y intercept (where it crosses the y axis)

It crosses at 4

The form of the equation is

y= mx+b, where m is the slope and b is the y intercept

y = 4/3x +4
