Phillip adds a number to its opposite number. what is the sum of these numbers?
a. a positive number
b. a negative number
c.0
d. a positive or negative number, depending on the numbers used

Option C) 0

Step-by-step explanation:

we know that

The opposite of a number is equal to the same number but with a different sign

The sum of a number with its opposite number is always equal to zero

Let

x > a number

The opposite of the number is equal to -x

Adds the number and its opposite

x+(-x)=0

therefore

The sum of these two numbers is zero

what graph

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
