Option c : 9 is the answer.
Explanation:
The expression is
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means
Thus, the expression can be written as
Adding the two numbers, we get,
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
Answer:
Step-by-step explanation:
To find the inverse of the function , the first step is to replace f(x) with "y":
The second step is to solve for the variable "x":
The third step is to interchange the variables, then:
Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:
Answer:
Step-by-step explanation:
Given:
Score of 37 with 107 minutes on social media.
Score of 41 with 73 minutes on social media.
The two pieces of information above can be thought of as two points on a line. Since the quiz score is a function of the number of minutes on social medial, let the number of minutes on social media be x and the score be y. The given information gives us two ordered pairs: (107, 37) and (73, 41).
Now we need to write the equation of a line that passes through these two points.
The two-point form of the equation of a line is:
We have ,
,
, and
.
