A linear inequality is an inequality that involves a linear function.
Examples of linear inequality are: 2x + y < 5, x + y > 2, y - x
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
A linear inequality can be gotten from a linear equation by changing the equality sign to any of the following inequality sign: >, < !=, >= and <=
So, examples of linear inequality are:
2x + y < 5, x + y > 2, y - x >= 2, 12x + 4y <= 20 and 6y - 7x > 1

If P is the incenter of triangle JKL, find the measure of JKP.
Answer:
m∠JKP = 31.5°
Step-by-step explanation:
Incenter of a triangle is the point where all the bisectors of interior angles intersect each other.
JN is the angle bisector of ∠KJL.
Therefore, m∠KJN = m∠LJN
(7x - 6) = (5x + 4)
7x - 5x = 6 + 4
2x = 10
x = 5
m∠KJN = (7x - 6)
= 7(5) - 6
= 35 - 6
= 29°
In ΔKJN,
m∠JKN + m∠KNJ + m∠NJK = 180°
m∠JKN + 90° + 29° = 180°
m∠JKN = 180°- 119° = 61°
Since KO is the angle bisector of ∠JKN,
m∠JKP = [tex]\frac{1}{2}(\angle JKN)[/tex]
= [tex]\frac{1}{2}(61)[/tex]
= 30.5°

Approximate Value Exact Value Error Absolute Error Ratio Percent Error
$100
$75
$25
How much was the absolute error in his estimate?
$
Intro
Answer:
Absolute error = $25
Step-by-step explanation:
Given that:
Amount spent by John on shopping trip = $75
Estimated amount to spent on shopping trip = $100
Absolute error = Approximate value - Exact value
Here,
Approximate value = $100
Exact value = $75
Absolute error = 100 - 75
Absolute error = $25
Percentage = [tex]\frac{Absolute\ error}{Exact\ value}*100[/tex]
Percentage = [tex]\frac{25}{75}*100[/tex]
Percentage = 33.33%
Hence,
Absolute error = $25

The line CD passes through the points C (2, -1) and D (1, 1). Which of the
following represents the equation of the line in Point-Slope Form?
Answer:
The equation of the straight line in point - slope form
y +1 = -2 ( x-2)
Step-by-step explanation:
Step(i):-
Given points are C( 2,-1) and D(1,1)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{1-(-1)}{1-2} = \frac{2}{-1} = -2[/tex]
m = -2
Step(ii):-
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
Final answer:-
The equation of the straight line
y +1 = -2 ( x-2)

Is it possible for the measure of an exterior angle of a triangle to be equal to the measure of a remote interior angle? Explain
Answer:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (Non-adjacent interior angles may also be referred to as remote interior angles.) FACTS: An exterior ∠ is equal to the addition of the two Δ angles not right next to it.
