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.

If there are more negative counters than positive counters, what will the sign of the sum be?

podryga [215]

Negative. If a negative number is "larger" (further away from zero) than a positive number, the result will be negative. You're basically subtracting a value that is greater than your starting value.

For example:
8 positive counters plus 18 negative counters:

This can be expressed as 8-18, which equals -10. The sign of the sum is therefore negative.
