determine if the two lines 7x-3y=-21 and y= "-3/7x+5" are parallel, perpendicular or neither

Answers

Answer 1

Answer:

They are perpendicular!

Step-by-step explanation:

Get 7x-3y=-21 into y=mx+b format.

7x-3y=-21           Bring 7x to the other side

-3y=7x-21          Divide -3 by both sides, it cancels out on the y's side.

y=-7/3x+7       Two negatives equal a positive, that it why 7 is positive.

y=-7/3x+7 is the line, the other is y=-3/7x+5

The slope of this line is -7/3 , the slope of the given line is -3/7.

Lines are perpendicular if the slopes are opposite reciprocals, such as this.

So, while they intercept at different points on the y-axis, they will intersect at some point! This makes them perpendicular.

Equation: What is it?

In a mathematical formula, the equal symbol (=) is used to denote that the statements are equivalent. It is demonstrated that many quantitative variables are comparable using mathematical equations, which are statements of reality. The equal sign, for instance, separates the numbers 12 and b + 6 into 2 halves within the equation y + 6 = 12. It is possible to calculate how many expression words each edge of a symbol represents. The meaning of a symbol usually contradicts itself.

Rachel's non-brokerage fee-related closing costs can be calculated by subtracting the brokerage fee from her total closing costs.

Explain mean, median, mode briefly?

In statistics, the mean, mode, and median are three measures of central tendency that describe a set of numerical data.

The mean is the average of a set of numbers, calculated by adding up all the values and dividing by the number of values. For example, if a set of data contains the values {1, 2, 3, 4, 5}, the mean is (1 + 2 + 3 + 4 + 5) / 5 = 3.

The mode is the value that appears most frequently in a set of data. For example, if a set of data contains the values {1, 2, 2, 3, 4, 4, 4, 5}, the mode is 4, because it appears three times, which is more than any other value.

The median is the middle value in a set of data when it is ordered in ascending or descending order. For example, if a set of data contains the values {1, 2, 3, 4, 5}, the median is 3, because it is the middle value. If there is an even number of values, then the median is the average of the two middle values.

It is important to note that different sets of data may have different measures of central tendency, and sometimes none of these measures may be appropriate.

Measures of central tendency are used to summarize and describe a set of data. The most common measures of central tendency are the mean, median, and mode.

1. Mean:

• Mean for June 2006: (508+435+538+913+367+033+254+240+137+022+160+548+260+458+358+035+222+879+136+371+127+586+201+316)/22 = $345,909

• Mean for June 2005: (422+843+469+588+245+803+199+409+132+054+139+728+254+725+345+065+210+740+134+334+125+455+184+853)/22 = $335,977

2. Median:

• Median for June 2006: Median of ordered data is the value in the middle of the data set, It is the 11th value in order set. we can see that it is $254,000

• Median for June 2005: Median of ordered data is the value in the middle of the data set, It is the 11th value in order set. we can see that it is $139,000

3. Mode:

• Mode for June 2006: There is no mode, because no value is repeated.

By multiplying the numerator and denominator by the same integer, it is possible to determine the equivalent fraction of each fraction.

Give a short note on triangle?

A triangle is a three-sided polygon that is defined by three points in a plane, called its vertices. The three sides of a triangle are also called edges, and are connected by three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles, including:

Right triangle: has one angle of 90 degrees.Acute triangle: all three angles are less than 90 degrees.Obtuse triangle: has one angle greater than 90 degrees.Isosceles triangle: has two sides of the same length.Equilateral triangle: has three sides of the same length.

Triangles are fundamental in mathematics and are used in many areas such as geometry, trigonometry, and engineering.

In a triangle, the measure of an angle is related to the lengths of the sides opposite and adjacent to it by the formula:

c = a/sin C

Given that c = 75 cm and mm∠C = 13°, we can use this formula to find the length of a:

a = c*sin C

where C is in radians.

a = 75 * sin(13°) = 75 * 0.2225 = 16.7 cm

Also, we know that the sum of the angles in a triangle is always 180°, so we can use that information to find the measure of angle A.

mm∠A = 180 - (mm∠B + mm∠C) = 180 - (154 + 13) = 180 - 167 = 13°

Therefore, using the Law of Sines, we can find the value of a.

[tex]\frac{a}{sin A}[/tex] =  [tex]\frac{b}{sin B}[/tex] = [tex]\frac{c}{sin C}[/tex]

a =  [tex]\frac{c*sin A}{sin C}[/tex]

a = [tex]\frac{75*sin(13^{0}) }{sin(154^{0}) }[/tex]

Now, you can use a calculator or a table of trigonometric values to find sin(13°) and sin(154°) and substitute them in the above equation to find the length of a. To the nearest tenth of a centimeter, a is approximately 18.6 cm.

Akio draws a graph to record the distance he rides on a long bike ride. What is the slope of the line for the first two hours? What is the slope of the line for all five hours? What does the slope mean in this situation?

Answers

Answer:

Below

Step-by-step explanation:

To find the slope of a line, we use the formula:

slope = (change in y-coordinates) / (change in x-coordinates)

In this case, if Akio recorded the distance he rode on his bike ride in hours, the slope of the line for the first two hours would be the change in the y-coordinates (distance) divided by the change in the x-coordinates (time) between those two points.

To find the slope of the line for all five hours, we will need to know the specific coordinates of all five points, otherwise, it's impossible to calculate the slope.

The slope of a line represents the rate of change in the y-coordinates (distance) per unit of change in the x-coordinates (time). In this situation, the slope represents Akio's speed, since the change in distance is divided by the change in time. A positive slope indicates an increase in distance over time, which means Akio is getting faster, whereas a negative slope indicates a decrease in distance over time, which means Akio is getting slower.

It's worth noting that a slope of zero would mean that there is no change in distance over time, which would mean that Akio isn't moving.

x = number of toppings
The price for a plain cheese pizza = $7
The price for each of the toppings = $1
Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x  is written as:

y = $7 + $1 × x

How to graph piecewise functions
Step by step

Please help, been stuck on thus question for 2 days

Answers

Answer:

  see attached

Step-by-step explanation:

You want to graph the piecewise defined function ...

  f(x) = 2x+9 for x < -3; 2x-2 for x > 4

Graph

You normally graph a line by finding (at least) two points on the line and drawing a line through them to make the graph. Often, it is convenient to start with the y-intercept. Here, it is convenient to start with the end point of the domain on which the line is defined. Additional points can be found by making use of the slope: rise 2 for each run of 1 to the right.

For x < -3, the value of y at x=-3 is ...

  y = 2(-3) +9 = 3

So, the point (-3, 3) will appear on the graph. This point is not actually in the domain, which is x < -3, so will be graphed as an open circle. The line goes down and to the left from there with a slope of 2.

For x > 4, the value of y at x=4 is ...

  y = 2(4) -2 = 6

So, the point (4, 6) will appear on the graph as an open circle, because x=4 is not actually in the domain of the function. The line will go up to the right from there with a slope of 2.
