Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
A. No, because -38 isn't a fraction.
2, No because 400 is a real number.

In any given week, salesman A earns $65 per sale, so his paycheck amounts to

(where

).
Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns

.
Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is

.
Step One
Factor f(x)
f(x) = (x + 5)(x - 2)
Step Two
The zeros occur when either (x + 5) = 0 or (x - 2) = 0
x + 5 = 0
x = -5
x - 2 =0
x = 2
Step 3
Record the zeros
(-5,0) or (2,0) <<<<<< answer.
It depends on what way the figure is translated, but it's possible it could be a dilations, reflection, rotation, etc.
