Answer:
x = 1/3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:
21x = 7
Divide 21 from both sides:
(21x)/21 = (7)/21
x = 7/21
x = 1/3
x = 1/3 is your answer.

Answer:
A. A reflection over the x-axis and a vertical stretch.
Step-by-step explanation:
Let 
, to obtain 
, we need to use the following two operations:
(i) Vertical stretch
, 
(ii) Reflection over the x-axis
Let prove both transformations in 
:
Step 1 - Vertical stretch (
)
Step 2 - Reflection over the x-axis
Hence, correct answer is A.
If you would like to know the equality of the expression 4 * x/5 - 2 * x/5, you can calculate this using the following steps:
<span>4 * x/5 - 2 * x/5 = (4 - 2) * x/5 = 2 * x/5
</span>
The correct result is 2 * x/5, which is none of the results written above.
