Answer:

4 3/11

Step-by-step explanation:

Find the function of the first two points

slope = delta y/delta x

slope = y1-y2/x1-x2

slope = (11-(-1))/(-10-1)

slope = 12/-11

Find the y intercept

y=(-12/11)x+b

-1 = (-12/11)*-1+b

-1 = 12/11+b

-23/11=b

y=(-12/11)x-23/11

Plug in x to find y

y=(-12/11)2-23/11

y= 4 3/11

This year is 2021.

2021 - 2005 = 16

x = 16

$f(x) = 12(1.12)^{x}$

$f(16) = 12(1.12)^{16}$

gtnhenbr [62]

The statement which holds true between -4 and -3 is; -4 < –3 The inequality changes from greater than to less than because -4 is less than -3.

<h3>Number line</h3>

The given inequality according to the task content is;

4 > 3.

On this note, when a negative sign is attached to each side of the inequality; it follows that;

The inequality sign is reversed and the inequality takes the form; -4 < -3.
