X = number of dimes
y = number of quarters
---
10x + 25y = 2565
y = x + 20

ANSWER
EXPLANATION
The given function is
When we plug in x=3 into this function, we obtain,
This means that the function is discontinuous at x=3.
We need to simplify the function to obtain,
This implies that,
The graph this function is a straight line that is continuous everywhere.
To graph
we draw the graph of
and leave a hole at x=3.
See diagram in attachment.
Hence the coordinates of hole is
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:
Knowing this, you can set up the following equation:
Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle .
This is:
A. 1.9 is an irrational number
3x+ 54=180
straight angle is 180
So just solve the equation.
subtract 54 on both sides.
126=3x
divide that by 3, and you get 42.
check You answer by multiplying 42 And 3, Which basically Is 126
and then 126+54
which is then 180
