Answer:
Step-by-step explanation:
46+x=77 subtract 46 from both sides
x=31
Answer: OPTION B
Step-by-step explanation:
You can observe that the exercise provides you two Linear functions.
The first Linear function is the function f(x). This is:

And the other Linear function is the function g(x):

In order to find
, you need to follow these steps shown below:
<u>Step 1</u>:
You must substitute the function f(x) into the function g(x); this means that the function f(x) will be in the place of the variable "x" of the function g(x); as you can observe below:

<u>Step 2</u>:
Finally you must combine the like terms (You can notice that the like terms are 1 and 14; then you must add them). Therefore, you get that
is:

Area = length x width
21 = length x 5
length = 21/5 = 4.2
The length is inversely proportional to the width because as the length increases the width reduces and vice-versa
