Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
We have,
Question 1. i.e. i.e. x = ±9.
Question 2. i.e. i.e. i.e.
Question 3. [tex]f(x)=x^{2}-144[tex]
For the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
So, the options are 12 and -12.
Question 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
So, Antoine is incorrect. There exists two solutions x=5 and x= -5.
Answer:
A
Step-by-step explanation:
Subtract 1 from both sides and divide by 2. This will leave you with x=-2 which is the simplified form of the equation.

yourdoing great sweetie you cant depend on other people when its time for the test so just ask your teacher for some after school tutering lessons if you really need it . sorry its not the answer you werelooking for but its the one you needed to hear.
Answer:
To be honest
Step-by-step explanation:
14
Given:
The of values of a function.
To find:
The ordered pairs that are found on the graph of the inverse function.
Solution:
If a function is defined as
Then its inverse function is defined as
From the given table it is clear that, the ordered pairs of the function f(x) are :
So, ordered pairs of the inverse function are :
Therefore, the correct option is B.
