To create an equation for a graph where y depends on x, identify the type of relationship presented by the graph. For a linear relationship, use the formula y = mx + b, where 'm' is the slope and 'b' is the y-intercept. Determine the slope using two points on the line and then solve for 'b' using the slope and one of the points.

Creating an equation for a graph where y depends on x is a common task in algebra. It's essential to identify the type of relation presented by the graph, which may include linear, quadratic, exponential, or logarithmic relationships. Let's assume, for example, that the graph represents a simple linear relationship.

In this case, you would use the formula for a line, which is y = mx + b. 'm' represents the slope of the line, and 'b' stands for the y-intercept.

To find the slope 'm', you can choose two points on the line and calculate the change in y divided by the change in x. Once the slope is determined, plug one of the points' coordinates into the equation and solve for 'b', the y-intercept. This will give you the equation for the line.

The equation for that graph, where y depends on x can be expressed in slope-intercept form as: y = -2x + 6.

To find the equation of the line, you can use the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. First, find the slope (m) using any two given points on the graph, i.e. (0, 6) and (4, -2):

[tex]\[ m = \frac{{\text{{change in }} y}}{{\text{{change in }} x}} = \frac{{-2 - 6}}{{4 - 0}} = \frac{{-8}}{{4}} = -2 \][/tex]

Now, substitute one of the points (e.g., (0, 6)) and the slope into the equation:

y = mx + b

6 = -2(0) + b

b = 6

So, the equation of the line is y = -2x + 6.

Answer:

(-2,-5)

Step-by-step explanation:

y=1/2x-4 and y=-2x-9

Just substitute one into the other and then solve for x. Then go back to get y.

1/2x-4=-2x-9

Add 4 on both sides

1/2x =-2x-5

Add 2x on both sides

2.5x=-5

Divide both sides by 2.5

x=-5/(2.5)=-2

Plug into y=-2x-9 to find y.

y=-2(-2)-9=4-9=-5.

Answer:

86

Step-by-step explanation:

Angles in a triangle add up to 180 degrees

add 74 with 20 to get 94

subtract 94 from 180 to get the value of x

180-94=86

The value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.

A triangle is a closed 2-dimensional polygon with three angles and three straight sides.

According to the Triangle Angle Sum Theorem, the sum of the three interior angles in a triangle is always 180°.

Hence,

angleA + angleB + angleC = 180°

Given the data in the question;

We substitute our given values into the expression above.

angleA + angleB + angleC = 180°

74° + 20° + x = 180°

94° + x = 180°

x = 180° - 94°

x = 86°

Hence, the value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.

Option D is correct.

Answer:

125 miles

Step-by-step explanation:

Write formulas for the amount of $ that would be due each of the two companies and set these equal to one another prior to solving for the number of days:

A:  $35 + ($0.45/mile)x  

B:  $60 + ($0.25/mile)x

Then $35 + ($0.45/mile)x = $60 + ($0.25/mile)x, or

($0.20/mile)x = $25

                                                                       $25

dividing both sides by $0.20 yields  x = ------------------- = 125 miles

                                                                    $0.20/mile

The charges made by the two companies would become equal after the 125th mile.  After that, Company B would become cheaper.

Ms. Call would need to drive at least 125 miles for the rental from Company B to be more cost-effective.

To find out when Company B becomes a better deal, we need to set up an equality and solve it for the number of miles. We can create the equation as follows:

Company A cost = Company B cost.

So, $35 + $0.45x = $60 + $0.25x.

Here x represents the number of miles driven. If we simplify this equation, we have:

$0.20x = $25.

Thus, solving for x: x = 25/0.20 = 125

So, Ms. Call would need to drive at least 125 miles in order for Company B to be a better deal.

[tex]W''(2, - 3)[/tex]

EXPLANATION

The given point bas coordinates

W(-2,3).

The mapping for reflection over the x-axis is

[tex](x,y)\to(x, - y)[/tex]

[tex]W(-2,3)\to \: W'(-2, - 3)[/tex]

This point W'(-2,-3) is then reflected over the y-axis.

The mapping for reflection over the y-axis is

[tex](x,y)\to (-x, y)[/tex]

[tex]W'(-2,-3)\to \: W''(2, - 3)[/tex]

Point W is initially transformed by reflecting it over the x-axis, which inverses the sign of the y-coordinate, followed by a reflection over the y-axis, which inverses the sign of the x-coordinate. The final position of point W" on the coordinate plane is therefore (2, -3).

To answer this mathematics question involving coordinate geometry and reflections, one must understand how reflections in the x-axis and y-axis affect the coordinates of a point.

A reflection of a point across the x-axis changes the sign of the y-coordinate, and a reflection across the y-axis changes the sign of the x-coordinate. Thus, if we start with point W at (-2,3), a reflection over the x-axis to create point W' changes the y-coordinate's sign, yielding point W' at (-2,-3). Then, reflecting W' over the y-axis changes the x-coordinate's sign, yielding our final point W" at (2,-3).

Step-by-step explanation:

If the graph of the function [tex]y=kf(x) +d[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If  [tex]0 <k <1[/tex] then the graph is compressed vertically by a factor k.

If  [tex]|k| > 1[/tex] then the graph is stretched vertically by a factor k

If [tex]k <0[/tex]  then the graph is reflected on the x axis.

If [tex]d> 0[/tex] the graph moves vertically upwards d units.

If [tex]d <0[/tex] the graph moves vertically down  d units.

In this problem we have the function [tex]y = cos⁡x[/tex]

And we know that The graph of [tex]y = cos⁡x[/tex] is transformed with  a vertical compression by a factor of 1/2 and a translation 3 units up

  400 = a^2

  √400 = 20 = a

option (a)

Step-by-step explanation:

Formula to calculate probability

a)

probability = number of times event occur  / total number of trials

Experimental probability of landing on white = 191/500 = 0.382

b)

probability = favourable outcome / total outcome

Theoretical probability of landing on white = 2/5 = 0.4

c)

As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.

The student must calculate frequencies, relative frequencies, and probabilities based on the results from spinning a dial. The frequencies are the counts of outcomes, relative frequencies are these counts divided by total spins, and probabilities are based on the assumption of a fair spinner.

The question is about filling in a table with the results from spinning a dial 500 times. This tasks involves calculating frequencies, relative frequencies, and probabilities which are fundamental concepts in probability and statistics. Since we do not have the actual results, I will explain the process of completing the table:

If an outcome occurred 100 times in 500 spins, the frequency is 100. To calculate the relative frequency, divide 100 by 500, which equals 0.2. Round this to the nearest thousandth to get 0.200.

Remember to round all your final calculated values appropriately as per the instructions given in the question.

Supplementary angles, totaling 180 degrees, are demonstrated by ∠2 and ∠4, as well as ∠3 and ∠5, in the context of lines b and c, as depicted in the diagram.

Supplementary angles are pairs of angles whose measures add up to 180 degrees. In the context of lines b and c, the identified supplementary angle pairs are ∠2 and ∠4, as well as ∠3 and ∠5. These pairs satisfy the condition that the sum of their measures equals 180 degrees. Visually, this relationship is evident in the provided diagram, reinforcing the concept of supplementary angles. Specifically, the equation ∠2 + ∠4 = 180° and ∠3 + ∠5 = 180° illustrates the supplementary nature of these angle pairs. Understanding supplementary angles is crucial in geometry, as it provides a fundamental principle for evaluating the relationships between angles formed by intersecting lines. In the given scenario, the angles ∠2, ∠4, ∠3, and ∠5 exhibit supplementary properties, emphasizing their collective role in forming a straight line and contributing to the overall understanding of geometric configurations.
