Use the equation y=3(1/2)^x to determine the value of y if x = -2

sergey [27]

Given :-

A Equation , $\sf y = 3(1/2)^x$

To find :-

The value of y at x = -2.

Solution :-

The given equation is ,

$\red{\longrightarrow}\sf y = 3(1/2)^x$

Now on substituting x = -2 , we have,

$\red{\longrightarrow} y = 3(1/2)^{-2}$

Using the property of exponents as ,

$\red{\longrightarrow} \sf a^{-m}= 1/a^m$

We have ,

$\red{\longrightarrow}\sf y = 3(2)^2$

$\red{\longrightarrow}\sf y = 3(4)$

$\red{\longrightarrow}\bf y = 12$

Hence the required answer is 12.

Explain why the solution of 5x – 3 > 14.5 or 2x+5/3 < 4 has a solution of all real numbers, with one exception.

AlexFokin [52]

Answer: The solution of given inequalities is all real number except [1.167, 3.5].

Explanation:

The given inequalities are

$5x-3>14.5$ ....(1)

$2x+\frac{5}{3}$ .... (2)

Solve first inequality.

$5x-3>14.5$

$5x>14.5+3$

$x>\frac{17.5}{5}$

$x>3.5$

Solve second inequality.

$2x+\frac{5}{3}$

$2x$

$x$

The solution of first or second inequality is all real number less than 1.167 and all rea number more than 3.5. It means the combined solution of both inequalities is all real number except [1.167, 3.5].
