We have that
<span>x - y = 4-------> multiply by -1-----> -x+y=-4-----> equation 1
x+ 2y = 4------> equation 2
add equation 1 and equation 2
-x+y=-4
x+2y=4
-----------------
0+3y=0-----> y=0
x+2y=4------> x+0=4------>x=4
the solution is the point (4,0)</span>

Answer:
A. People who are related to the employees of Isaac's Immaculate Ice Cream
Step-by-step explanation:
If the results are called into question, this means there is potential bias in the survey.
Randomly choosing people from a phone book or another random method would not create bias.
Having people blindly test brands of ice cream would not create bias, as it is random and fair.
However, if the people surveyed were related to employees of Isaac's Immaculate Ice Cream, the results could be called into question over a fear of favoritism.
A good place to start for this question is to define the properties of the geometric terms you are given.
Quadrilaterals have four straight sides.
Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.
Trapezoids are also quadrilaterals. They have only one pair of parallel sides.
So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.
