Thalia, a quiz show contestant, answered 20 questions. She was awarded 2 points for every correct answer that she gave, but she
DIA [1.3K]

The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28. Instead modifications should have been made before applying the equation.

<h3>What is an Equation ?</h3>

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

Total Questions = 20

Total Points = 28

Correct Answers = +2 points

Incorrect Answers = -1 point

The viewer represents the correct answers with x and the incorrect ones with y.

x+y = 20

for every correct answers 2 points;

and for every incorrect answers, -1 point

This can be written as

2x-y = 28

The viewer's mistake is that; instead of subtracting total incorrect points from the correct points, the viewer added them together;

now

2x-y = 28

x+y = 20

On adding the equations

]3x = 48

x = 16

y = 4

This means that the contestant answered 16 questions correctly and 4 questions incorrectly

The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28.

Consider the line y=-1/2x+8
OverLord2011 [107]

Given parameters:

Equation of the line is y = -\frac{1}{2} x + 8

Unknown:

Slope of line parallel to this line = ?

Slope of line perpendicular = ?

Solution:

A line parallel to this line will have the same slope with it.

A line perpendicular will have the negative inverse of this slope;

Slope of line  = - \frac{1}{2}

Slope of line parallel to this line = -\frac{1}{2}

Slope of line perpendicular = negative inverse = -( -(\frac{1}{\frac{1}{2} }))   = 2

So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2
