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:

Answer:
59°
Step-by-step explanation:
From the diagram, shown in the attachment line x and y are parallel lines.
Angle 7 and angle 6 are angles on a straight line.
The two angles will add up to 180 degrees.

But angle 7 measures 121°.
This implies that:

Solve for angle 6 to get;

sumalee has 16 friends because she gave away 32, if you divide 32 by 2 its 16 cuz thats how many she gave away to each person
Answer:
D) They are complementary angles.
