On the third step it adds 8 on both sides. You are suppose to subtract 8 on both sides.
F(x) = 1, so we make the entire equation equal 1.
1 = sqrt(x) + 7
To make x by itself subtract 7 from both sides
-6 = sqrt(x)
Square both sides to remove sqrt from x.
36 = x
The value of x is 36
Answer:
A
Step-by-step explanation:
The line is divided into 9 parts between 1 and 2
A is situated 6 parts of the way between 1 and 2, that is
=
← cancelling by 3
Hence
A = 1 +
= 1
→ A
Answer:
A firm determines its profit by subtracting "Total Cost" from "Total Revenue".
