Answer:

$-\frac{4}{3}$ (Your answer choices were really confusing, so I just put the plain answer)

Step-by-step explanation:

To find the slope of a line with just two points, we can use the formula $\frac{y2-y1}{x2-x1}$ . In this case, $\frac{5-(-3)}{2-8}$ . This is $\frac{8}{-6}$ . This reduces to $-\frac{4}{3}$

Answer:

x=0 , x=-3

Step-by-step explanation:

Apply all exponent rules:

$3^{x+3}$ = $3^{x}$ × $3^{3}$

$\frac{1}{3^{x} }$ = $(3^{x} )^{-1}$

Rewrite equation with $3^{x}= u$

$u$ × $3^{3}$ + $u^{-1}$ - 28 = 0

Solve for u to give :

u = 1, u = 1/27

Substitute back u = $3^{x}$ , solve for x :

$3^{x}$ = 1 , x= 0

$3^{x}= \frac{1}{27}$ , x= -3
x=0 , x=-3

Substituting x back into original equation verifies our answers

Answer:

$73,564,723.80

Step-by-step explanation:

"x is the number of years after the expansion in 2005"

This year is 2021.

2021 - 2005 = 16

x = 16

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

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

$f(16) = 73.56$

Answer: $73,564,723.80

The range is the difference between the lowest number and the highest number.

If x was the lowest number, then the highest number shown is 49

X = 49- 58 = -9

If x was the highest number, the lowest number given is 3

X = 3 + 58 =61

The two values would be -9 and 61
