Answer:
Step-by-step explanation:
since we know that the 50 degrees is one side of the line then the angle that is strait opposite from this angle is 50 degrees, so 50+60=110degrees and 180-110=70, so x=70 degrees
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:
−25x^2+5x−1/2
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
If you graph x=-1, you will get a line with x-intercept -1 and no y-intercept. If you do not have either of these things, your line does not have a constant slope.
