Step-by-step explanation:
x = number of multiple choice questions
y = number of short response questions
x + y = 15
5x + 10y = 100
=>
x + 2y = 20
let's subtract the first from the second equation :
x + 2y = 20
- x + y = 15
--------------------
0 y = 5
x + y = 15
x + 5 = 15
x = 10
to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b
a is the slope, b is the y- intercept.
x + y = 15
transforms to
y = -x + 15
this line goes e.g. through the points (0, 15) and (1, 14).
and
x + 2y = 20
transforms to
2y = -x + 20
y = -x/2 + 10
this line goes e.g through (0, 10) and (2, 9).
the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.

This will have no equal sign because that is what an expression is. The sentence translated into numbers is:
<h3>(x-10)(x)</h3>
Answer:
<em>N </em>is located in the third quadrant
Step-by-step explanation:
since the y coordinate is a negative and so is the x coordinate, the negative y would push <em>N </em>down and the negative x would push it left, landing the coordinates of <em>N</em> in the 3rd quadrant.
