Answer: Any line with slope of -3/4
Reason:
Let's calculate the slope of the line through those two points
[tex](x_1,y_1) = (1,3) \text{ and } (x_2,y_2) = (4,7)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{7 - 3}{4 - 1}\\\\m = \frac{4}{3}\\\\[/tex]
The slope of the line is 4/3
Anything perpendicular to this has a slope of -3/4. I flipped the fraction and flipped the sign (from positive to negative).
So for example, the answer may be something like [tex]y = -\frac{3}{4}x+5[/tex] or [tex]y = -\frac{3}{4}x-2[/tex]. All that matters is the -3/4 out front of the x.
Side note: the original slope 4/3 and perpendicular slope -3/4 multiply to -1

If h(x)= -5/6x + 7/8 find the following values. Simplify your answer.
H(3)=
H(4)=
H(-1/2)=
If [tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] then the value of h(3) = -13/8 , h(4) = -59/24 , h(-1/2) = 31/24 .
In the question , the equation is given as
[tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] ....(i)
Part(a)
To find the value of h(3)
we substitute the value of x=3 .
On substituting the value of x=3 in equation (i),
we get ,
h(3) = (-5/6)3+7/8
= -15/6+7/8
taking LCM of 6 and 8 as 24, we get
= -60/24 + 21/24
= (-60+21)/24
= -39/24
Writing in the simplest form we get
= -13/8
so, the value of h(3)= -13/8 .
Part(b)
for h(4) ,we substitute the value of x=4 .
On substituting the value of x=4 in equation (i) ,
we get ,
h(4) = (-5/6)4+7/8
= -20/6+7/8
taking LCM of 6 and 8 as 24, we get
= -80/24 + 21/24
= (-80+21)/24
= -59/24
so , the value of h(4)= -59/24 .
Part(c)
for h(-1/2) ,we substitute the value of x as -1/2 .
On substituting the value of x = -1/2 in equation (i) ,
we get ,
[tex]h(\frac{-1}{2} )=\frac{-5}{6} *\frac{-1}{2} +\frac{7}{8}[/tex]
= 5/12 +7/8
taking LCM of 12 and 8 as 24, we get
= 10/24 + 21/24
= (10+21)/24
= 31/24
so , the value of h(-1/2)= 31/24 .
Therefore , if h(x) = (-5/6)x+7/8 the the value of h(3)= -13/8 , h(4)= -59/24 and h(-1/2)= 31/24 .

7) In the given figure, PQR is an equilateral triangle with coordinates of Q and
R as (-2, 0) and (2, 0) respectively. Find the coordinates of the vertex P.
The coordinates of the vertex P is calculated as (0,2√3).
What is defined as the distance formula?The distances among two points as a characteristic of their coordinates are given by an algebraic expression (like coordinate system).
The Pythagorean theorem is used to derive distance formulae for points in rectangular coordinates in 2- and three-dimensional Euclidean space.Because it has a starting and ending point, a line segment can be graphed in both two-dimensional and three-dimensional coordinate planes.Because of the two-dimensional coordinate plane, the starting and stopping points can also be marked as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), culminating in the distance formula as: d = √(x₂ - x₁)² + (y₂ - y₁)².Now, according to the given question;
The coordinates of the points Q and R is given as;
Q and R as (-2, 0) and (2, 0).
Now, as the all three points P,Q and R forms the equilateral triangle. Then, the distance of each side or the distance between two consecutive points are equal.
Calculate the distances between the points;
Distance between Q and R;QR = √(2 + 2)² + (0 - 0)²
QR = 4
Distance between Q and P;Let the coordinated of P be (x, y);
Then,
QP = √(x + 2)² + (y + 0)²
QP = QR = 4
4 = √(x + 2)² + (y)² ........(equation 1)
Distance between R and P;RP = √(x - 2)² + (y + 0)²
RP = QR = 4
4 = √(x - 2)² + (y)² ........(equation 2)
Equating equation 1 and 2.
√(x + 2)² + (y)² = √(x - 2)² + (y)²
Squaring both side;
(x + 2)² + (y)² = (x - 2)² + (y)²
x² + 4 - 4x + y² = x² + 4 - 4x + y²
Simplifying the equation;
x = 0.
Put the value of x in equation 1;
4 = √(x + 2)² + (y)²
y = 2√3.
Therefore, the coordinates of the point P are found to be (0, 2√3).

Explain the properties used to solve inequalities and how they are different from properties of equality
The major difference between inequality and equality is that equality represents a particular value(s) while inequality represents a range of values that are in a specific direction.
What are the properties that are used to solve inequalities?This must be noted when solving questions on equality and inequality.
For example:
x = a means that the value of x is a. It represents a particular value which is a
x < a represents all the values that are less than a.
x ≤ a represents values from a and below.
x > a represents all the values that are greater than a
x ≥ a means that the values of x are greater than or equal to a.
From the examples given above, it is obvious that a change in the direction of the inequality sign changes the values of the data represented by the inequality.

a data set includes the following numbers: nineteen over 4, two and one fifth, 85%, and 3.24. part a: what is the order of the numbers from least to greatest?
The order of the numbers from least to greatest is:
85% < Two and one fifth < 3.24 < Nineteen over 4
The given data set of numbers are: nineteen over 4, two and one fifth, 85%, and 3.24
In order to compare these numbers, we will change all of them into float (decimal) format.
nineteen over 4 = 19/4 = 4.75
two and one fifth = 2 [tex]\frac{1}{5}[/tex] = 11/5 = 2.2
85% = 85/100 = 0.85
