if p=the mounttain bike's orginal price in dollars, which algebraic expression represents the reduced price ?
Algebraic expression (C) p - 125 represents the reduced price.
What do we mean by algebraic expressions?In mathematics, an algebraic expression is an expression made up of variables and constants as well as algebraic operations (addition, subtraction, etc.). Expressions are made up of terms. Algebraic expressions have at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.So, if p is the mountain bike's original price.
Then, the reduced price will be p - 125.Therefore, algebraic expression (C) p - 125 represents the reduced price.

Position and label each triangle on the coordinate plane. (Lesson 4-8)
Isosceles ΔQRT with base QR that is b units long.
The isosceles triangle's base can be positioned along the x-axis. Because QR is b units long, you can position point R along the x-axis and calculate the coordinates (b, 0).
What is meant by an isosceles triangle?
An isosceles triangle is a triangle with at least two equal-length sides in geometry. It is sometimes specified as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter version including the equilateral triangle as a special case.
By putting Q at the origin, the isosceles triangle's base can be positioned along the x-axis. Because QR is b units long, you can position point R along the x-axis and calculate the coordinates (b, 0). Because the vertex of the isosceles triangle, point T, is directly above the midpoint of the base, its x-value is half the length of QR and its coordinates are (b/2, c).

Below are two parallel lines with a third line
intersecting them.
46°
What is x equal to?
Answer:
x = 134°
Step-by-step explanation:
The angle labelled [tex]x^{\circ}[/tex] and the 46° add up to 180° as they are co-interior angles.
∴ [tex]x^{\circ} + 46^{\circ} = 180^{\circ}[/tex]
⇒ [tex]x^{\circ} = 180^{\circ} - 46^{\circ}[/tex] [Subtracting 46° from both sides]
⇒ [tex]x = 134^{\circ}[/tex]
Therefore [tex]x[/tex] is equal to 134°.
A homeowner whose house was assessed
at $120,000 pays $1,800 in taxes. At the
same rate, what is the tax on a house
assessed at $135,000? PLS SOMEONE HELP me !!!And ty !!!
Thus the tax rate is 1.5% and the 1.5% tax value of $135,000 is $2025.
How do we find the tax rate?We are given that;
A homeowner whose house was assessed at $120,000 pays $1,800 in taxes.
At the same rate, we need to find out what the tax value on a house assessed at $135,000.
The rate is always in percentage. Thus;
Tax value = 5% of 100
= 5/100 x 100
= $5
We have,
House cost = $120,000
Tax amount = $1800.
Let the rate be R%
Now;
R/100 * 120,000 = 1800
R * 1200 = 1800
R = 1800/1200
R = 18/12 = 1.5
R = 1.5%
The tax rate is 1.5%
The 1.5% tax value of $135,000 = 1.5 / 100 * 135,000
= 15/1000 x 135,000
= 15 x 135
= $2025
The tax value is $2025.
Thus the tax rate is 1.5% and the 1.5% tax value of $135,000 is $2025.

i need to know how to solve this
Answer:
let's say (5x + 2) = y
then that means 118° + y = 180°(angle in a straight line)
therefore y =180 - 118= 62°
since y = 5x + 2
and y= 62°
therefore 5x + 2 = 62°
5x = 62- 2= 60°
therefore 5x = 60°
this means that x = 60 ÷5 = 12°

An artist uses gold leaf foil in his work. he wants to cover a piece of canvas that is 22.5 by 34 inches with this foil. the foil costs $4.15 per square inch. how much money will the artist spend on gold leaf foil for his project?
If an artist uses gold leaf foil in his work and he wants to cover a piece of canvas that is 22.5 by 34 inches with this foil and the foil costs $4.15 per square inch, then the money the artist spent on gold leaf foil for this project is equal to $3174.75
The money spent on gold leaf foil for the project can be calculated by the multiplication of the area or square inch of the foil needed to cover the piece of canvas with the price per square inch.
The area or square inches can be calculated by multiplying the length in inches by the width in inches.
Area = 22.5 × 34
Area = 765 square inches
Now, money spent on gold leaf foil can be calculated by multiplication of the area of the need with the price per square inch.
Area × price per square inch
765 × 4.15 = $3174.75
Hence the money the artist spent on gold leaf foil is calculated to be $3174.75

From the given graph, we have that:
The constant of the relationship on the graph is of 5.The point (7,35) in the proportional relationship graphed in this problem means that 35 gallons of water were used in 7 minutes.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality, in the case of a direct relationship, as follows:
y = kx
In the case of an inverse relationship, we have that:
y = k/x.
k is the constant of proportionality for both cases.
For this problem, the function goes through point (2,10), that is, when x = 2, y = 10, meaning that we can find the constant k as follows:
2k = 10
k = 10/2
k = 5.
The constant of the relationship on the graph is of 5.
For the relationship, we have that:
The input x is the time in minutes.The output y is the water used in gallons.Hence:

What is referred as the arithmetic progression?An arithmetic progression is a series of numbers that have a set common difference in between two consecutive numbers (A.P.).
Each term in an arithmetic sequence increases or decreases by adding or subtracting a constant term.
a = 30 for the first term
d = 40, common difference
We solve in what term is closest to 300 in this manner;
300 / 40 = 7.5
Thus, find the 7th and 8th term.
7th is solved by verifying for;
a₇ = a + ( n - 1 ) d
a₇ = 30 + ( 7 - 1 ) 40
a₇ = 30 + 240
a₇ = 270
The 8th term to certify the closest;
a₈ = T7 + d
a₈ = T7 + 40
a₈ = 270 + 40
a₈ = 310

Find the measures of each numbered angle.
c. ∠ 4
Measure of angle 4 i.e. m∠4 = 50°
What is measurement of an angle ?The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.
How to find angle measurement ?As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.
In the question,
Let given angle is ∠8.
Given, ∠8 = 50°
Now, according to vertical angle property
∠5 = ∠8
therefore, ∠5 = 50°
Also, ∠5 = ∠4 (alternate interior angles)
Thus, m∠4 = 50°

The coordinates of the vertices of quadrilateral are A(-6,-1),B(-5,2),C(-1,-5), and D(0,-2). Parker states that quadrilateral is a parallelogram. Prove or disprove Parker’s statement.
=======================================================
Explanation:
Use the slope formula to find the slope of the line through A(-6,-1) and B(-5,2)
[tex](x_1,y_1) = (-6,-1) \text{ and } (x_2,y_2) = (-5,2)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2 - (-1)}{-5 - (-6)}\\\\m = \frac{2 + 1}{-5 + 6}\\\\m = \frac{3}{1}\\\\m = 3\\\\[/tex]
The slope of segment AB is 3.
-------------
Repeat these set of steps for segment CD
C = (-1,-5)
D = (0,-2)
[tex](x_1,y_1) = (-1,-5) \text{ and } (x_2,y_2) = (0,-2)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-2 - (-5)}{0 - (-1)}\\\\m = \frac{-2 + 5}{0 + 1}\\\\m = \frac{3}{1}\\\\m = 3\\\\[/tex]
The slope of segment CD is also 3
Parallel lines have equal slopes, but different y intercepts.
Since AB and CD have the same slope of 3, this shows AB is parallel to CD.
--------------
Now find the slope of segment BD
B = (-5,2)
D = (0,-2)
[tex](x_1,y_1) = (-5,2) \text{ and } (x_2,y_2) = (0,-2)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-2 - 2}{0 - (-5)}\\\\m = \frac{-2 - 2}{0 + 5}\\\\m = -\frac{4}{5}\\\\[/tex]
Segment BD has a slope of -4/5
--------------
Lastly, compute the slope of segment AC
A = (-6,-1)
C = (-1,-5)
[tex](x_1,y_1) = (-6,-1) \text{ and } (x_2,y_2) = (-1,-5)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-5 - (-1)}{-1 - (-6)}\\\\m = \frac{-5 + 1}{-1 + 6}\\\\m = -\frac{4}{5}\\\\[/tex]
Segment AC has a slope of -4/5
Both segments BD and AC have the same slope of -4/5.
Therefore, segments BD and AC are parallel
----------------
We have two pairs of opposite parallel sides. Ultimately figure ABDC is a parallelogram
