5(x+4)-3x+3=5 solve for x
Elena L [17]

Answer: X= -9

Step-by-step explanation:

Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.

Then subtract or add the like terms

5x-3x and 20+3. It will be 2x+23=5

Then add -23 to both sides

It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x

2x/2=-18/2 then the final answer is x= -9. I hope it help

Which of these is an exponential parent function?  A. f(x) = 2^x – 3  B. f(x) = 2^x + 2  C. f(x) = 2^x  D. f(x) = 2^x + 1/3
anygoal [31]

An exponential parent function is the option C. f(x)= 2^{x}, from the given options.

What do you mean by exponential parent function?

The formula for their parent function is y = b^{x}, where b is any non zero constant. Below is a graph of the parent function, y = e^{x}, which demonstrates that it will never equal 0. And at y = 1 when x = 0, y crosses the y-axis.

According to options in the given question,

We have the option below in the given question:

A. f(x) = 2^x – 3 

B. f(x) = 2^x + 2 

C. f(x) = 2^x 

D. f(x) = 2^x + 1/3

We know from the above definition that the option C. is the right answer to the given question.

Therefore, the exponential parent function is f(x)= 2^{x}.
