Answer:
9x +81
Step-by-step explanation:
because you cant add 9x to anything but something with x
Answer:
All Real Numbers
Step-by-step explanation:
<u>The Domain for a function simply is all the possible x values.</u>
When graphing this function, you'll realize that it's continuous and passes all x values.
Additionally, when looking at it, you'll realize you can input any number of your choosing.
When trying to evaluate the domain of other functions, you can look at if any values of x will create an undefined value.
For example, some functions may have x in the denominator, and since the denominator can not be 0, there will be a discontinuity.
Other examples where the domain wouldn't be all real numbers would be if x was under a square root and couldn't be negative, or if the function was a vertical line.
Hope that helps, please let me know if you have any queries.
Answer:
7/16
Step-by-step explanation:
3/4*7/12=21/48=7/16
Answer:
Step-by-step explanation:
Use trig ratios to solve for x. Side x is adjacent to the reference angle of 61 degrees, and the side that measures 59 is opposite the reference angle. This is the tangent ratio:
and
so
x = 32.7
For this case we propose a rule of three:
foot -------------> hour
x -----------------------------------> 1 hour
Where "x" represents the amount of foot in one hour.
So, we have foot every hour.
Answer:
foot every hour
