Answer:
d. put an equal sign between the two expressions, and solve for x
Step-by-step explanation:
The two expressions are :
and
We can say that is LHS and we have to solve it to become equal to RHS or
Now we have to tell procedure can Ahmed follow to determine if the two expressions are equivalent. For equivalent equations we put an equal sign between the expressions and solve them.
Solving LHS or
Cancelling out 4 we get:
or the RHS
Therefore, option D is the correct answer.

Answer:
The graph shifts 7 units left and 2 units up.
Step-by-step explanation:
In transformations, when a number is added or subtracted to "x" directly, that is the left/right shift.
When a number is added or subtracted outside of the "rest" of the equation, that is the up/down shift.
I learned transformations with these variables:
"a" - vertical stretch (a > 1) or compression (0 < a < 1)
"k" - horizontal stretch (0 < k < 1) or compression (k > 1)
"c" - translate left (+) or right (-)
"d" - translation up (+) or down (-)
The untranslated graph is centred around the origin f(x) = 1/x
f(x) begins 3 units right and 1 unit up of the untranslated graph.
g(x) is 4 units left and 3 units up of the untranslated graph.

There is a 7 units translation left and 2 units translation up.
