b. The slope of median of triangle passing through point R is 1/4.

c. The slope of the altitude of the triangle that passes through point R doesn't exists.

What is slope of a line segment ?

Slope is the ratio of the difference in y-coordinates over the equivalent x-coordinates between two different locations on a line.

It is given that the vertices of a triangle are P(-6,1), Q(-2,-5) and R(8,1).

a.

The midpoint (M) of QR will be equal to

( [tex]\frac{-2 + 8}{2} , \frac{-5 + 1}{2}[/tex] )

or

M = (-3 , 2)

Now , slope of line QR will be ;

[tex]m_{QR}[/tex] = [tex]\frac{1+5}{8+2}[/tex]

[tex]m_{QR}[/tex] = 6 / 10

We know that :

m × [tex]m_{QR}[/tex] = -1

m = -10 / 6

or

m = -5 / 3

Equation of line will be given as :

y + 2 = [tex]\frac{-5}{3}[/tex] ( x - 3 )

y = [tex]\frac{-5}{3}[/tex] x + 3

b.

The midpoint of PQ will be :

= ([tex]\frac{-6 - 2}{2} , \frac{1 - 5}{2}[/tex])

= ( -4 , -2)

The slope of median of triangle that passes through point R will be ;

m = [tex]\frac{-2 - 1}{-4-8}[/tex]

m = -3 / -12

m = 1/4

or

m = 0.25

c.

Slope of altitude of triangle that passes through point Q will be :

m = [tex]\frac{1 - 1}{-6-8}[/tex]

m = 0 / -14

m = 0

The slope in this case doesn't exist.

Therefore the answers will be :

a. The equation of perpendicular bisector of QR is y = [tex]\frac{-5}{3}[/tex] x + 3.

b. The slope of median of triangle passing through point R is 1/4.

c. The slope of the altitude of the triangle that passes through point R doesn't exists.

Since the line Lloyd drew also passed through the point (1, n) for some number n, the number n represents: (A) the price, in dollars, per ounce of pumpkin.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the points on a cartesian coordinate are generally written as an ordered pair (x, y) which represents the horizontal line and vertical line respectively.

Since the line Lloyd drew also passed through the point (1, n) for some number n, we can reasonably infer and logically deduce that the number n represents the price, in dollars, per ounce of pumpkin.

Second part;

A word problem that involves multi step linear equations is as follows;

How much does a cake cost

How much does an orange drink cost

Solution;

Let c represent the cost of a cake and let o represent the cost of an orange drink, we have;

2•c + o = 0.4...(1)

3•c + 3•o = 0.9...(2)

Multiplying equation (1) by 3 and subtracting equation (2) from the result, gives;

3×(2•c + o) - (3•c + 3•o) = 3×0.4 - 0.9

Which gives;

3•c = 0.3

c = 0.3/3 = 0.1

c = 0.1

The cost of one cake, c = $0.1

From equation (1), we have;

2•c + o = 0.4

Which gives;

2×0.1 + o = 0.4

o = 0.4 - 2×0.1 = 0.2

Angles are formed when two or more lines intersect. This in other words means that angles is the measure of space between the intersection of rays or lines

The figure that completes the question is added as an attachment

The given parameter is the angles in the figure

From the figure, we have the following angles:

Angle 1 = 23

Angle 2 = 7x - 5

Angle 3 = 67

The relationship between the above angles is

Angle 1 + Angle 2 = Angle 3

This is so because the angles 1 and 2 are adjacent angles and they add up to angle 3

Substitute the known values in the above equation

So, we have

23 + 7x - 5 = 65

Collect the like terms in the above equation

So, we have

23 - 5 + 7x  = 65

Evaluate the like terms in the above equation

So, we have

The solution of the equation √5 x + 1 - 2√x = 1 is [tex]\frac{4}{5}[/tex].

An extraneous solution is one that results from the process of addressing the problem but is not a legitimate solution to the problem, such as the answer to an equation.

Consider the equation,

√5 x + 1 - 2√x = 1

Subtracting 1 from each side of the equation.

√5 x + 1 - 2√x - 1 = 1 - 1

√5 x - 2√x = 0

√5 x = 2√x

Dividing each side of the equation by √x.

( √5 x/√x ) = ( 2√x / √x )

√(5x) = 2

Squaring each side of the equation.

[ √(5x) ]² = (2)²

5x = 4

Dividing by 5 from each side of the equation.

( 5x/5 ) = ( 4/5)

x = 4/5

Now checking the extraneous solution:

[tex]\sqrt{5}x + 1 -2\sqrt{x} =1\\\sqrt{5}(\frac{4}{5} ) + 1 - 2(\sqrt{\frac{4}{5} } ) = 1\\ \frac{4}{\sqrt{5} } + 1 - \frac{4}{\sqrt{5} } = 1\\ 1 = 1[/tex]
