Answer: X = 88, Y = 26, Z = 11.2

Step-by-step explanation:

First thing is use any linear pair equation that only has one variable.

1. 2x-30 + 34 = 180, Y = 88

Plug in the value of X to a two-variable equation to find the value of y.

2. 2y +88 + 40 = 180, Y = 26

Lastly repeat this step for finding the value of z.

3. 88 + 39 + 5z - 3 = 180, Z = 11.2

Answer: x = 88, y = 26, z = 26

Step-by-step explanation:

The shape shown in the picture is a heptagon.

Sum of interior angle = 900 degrees

Add all the interior angles

x+40+x+22+142+x+39+133+2x-30+114

=5x+460

5x+460=900

5x = 440

x = 88

2y is the exterior angle of x+40

to get 2y, you need to subtract x+40 from 180.

x = 88,

x+40 = 128

2y = 180-128 = 52

y = 26

5z-3 is the exterior angle of x+39

same thing for 5z-3

x = 88,

x+39 = 127

5z-3 = 127

5z = 130

z = 26

Answer: The function y = 5/x is a reciprocal function, which means the graph of the function will be a hyperbola.

The error the student made could be in the following ways:

The student might have plotted the graph as a straight line instead of a hyperbola

The student might have neglected to reflect the graph across the y-axis, since the function is not defined for x = 0

The student might have not plotted the asymptotes of the graph. The graph will have vertical asymptotes at x = 0 and x = infinity.

To correct the error, the student should plot the graph as a hyperbola with vertical asymptotes at x = 0 and x = infinity. And also reflect the graph across the y-axis.

Answer:

y - (-2) = -5/3 (x-6)

Step-by-step explanation:

Using Slope Point Formula (y-y1=m(x-x1) we can use the given slope, and the given coordinate to fill in the equation.

So y1 would be -2 because we only have 1 coordinate, and -2 is the y value. So we have y-(-2)=m(x-x1)

Now we have the slope which is m. The slope is -5/3, so we plug that into m. So now we have y-(-2)=-5/2(x-x1).

Last we plug in x1 to the equation which is 6. So to finish the equation we have y-(-2)=-5/3(x-6).

The area issue with the suggested remedy is that the playing field is 118 feet by 56 yards in size.

To determine area, multiply length by width. L times B is the formula for calculating area. Area or Radius = r2(=3.14) These methods can also be used to calculate the areas of different quadrilaterals, which are polygonal shapes with four sides and an aspect lower than 90 degrees. Application. Since its inception, area has been the foundation of geometry.

Here,

Our calculation of w = 56 reveals that the parallelogram is 56 yards long.

We can simplify the calculation by altering w to 56 in order to obtain the length of the rectangle but since width is the same as 2w + 6 already.

The rectangle is depicted as having a length of 118 yards.

Accordingly, the playing field measures 118 yards by 56 yards.

Therefore, the size of the game field—118 yards x 56 yards—is the solution to the current problem.

Answer: Morgan will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.

Step-by-step explanation: To solve this problem, we can use the formula: distance = speed x time.

We know that at 15km/h, Morgan reaches Town B at 6pm, and at 20km/h, she reaches Town B at 5pm.

We can use this information to find the distance between Town A and Town B and the time it takes to travel this distance at 25 km/h.

First, let's find the distance between Town A and Town B:

distance = speed x time

distance = 15 km/h x time

time = distance / 15 km/h

time = (distance / 15) hours

Since we know that when Morgan travel at 15km/h to reach town B at 6pm, we can use the time to calculate the distance:

time = 6pm - 5pm = 1hour

distance = 15 km/h x 1 hour = 15 km

Next, we can use this distance and the new speed 25km/h to calculate the arrival time:

time = distance / speed

time = 15 km / 25 km/h = 0.6 hours = 36 minutes

So, she will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.

Please note that this calculation is assuming that the distance between Town A and Town B is a constant, and assuming that the time of arrival at 15km/h and 20km/h are accurate.

Answer: The y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. ✅

Step-by-step explanation:

PLEASEEEE GIVE BRANLIEST

The y-intercept is a point on the graph where the line of the function crosses the y-axis. It is represented by the number that is next to the y in the equation of a line (y = mx + b).

The slope is the steepness of the line and it is represented by the number that is next to the x (y = mx + b).

In part A, the y-intercept is 2 and the slope is 3. This means that the line starts at the point (0,2) and for every 1 unit on the x-axis, it goes up 3 units on the y-axis.

In part B, the y-intercept is -5 and the slope is 2. This means that the line starts at the point (0,-5) and for every 1 unit on the x-axis, it goes up 2 units on the y-axis.

So the difference between part A and part B is that the y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. This means that the line in part A starts at a different point and is steeper than the line in part B.

Answer:

In the context of a linear function, the y-intercept is the point where the line crosses the y-axis and the slope is the rate at which the line increases or decreases as the x-value increases. If two functions have different y-intercepts, it means that they have different starting points on the y-axis. Similarly, if two functions have different slopes, it means that they have a different rate of change. So, in part A and part B, if the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have a different starting point on the y-axis and a different rate of change respectively.

Step-by-step explanation:

In the context of a linear function, a line can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is the point where the line crosses the y-axis. It is represented by the value of b in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the y-intercept is (0,3).

The slope of the line is the rate at which the line increases or decreases as the x-value increases. It is represented by the value of m in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the slope is 2.

If the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have different starting points on the y-axis and a different rate of change respectively.

For example, if the equation of the function in part A is y = 2x + 3, the y-intercept is (0,3) and the slope is 2. And if the equation of the function in part B is y = 4x + 1, the y-intercept is (0,1) and the slope is 4. Therefore, the y-intercept and slope of part A are different from the y-intercept and slope of part B.

The correct option is B, a vertical dilation by a factor of 3 and a horizontal shift to the right 2 units transformations are applied to the graph of the function f(x)=10^x to produce the graph of the function g(x)=3(10)^x-2.

An illustration of data or a mathematical function is a graph. Usually, it consists of a collection of plotted points or coordinates connected by lines or curves. A graph's main function is to show the relationship between two or more variables, which facilitates better comprehension and interpretation of the data.

The graph of the function f(x) = 10x is a three-fold vertical extension of the graph of y = 10x. In order to create the graph of g(x) = 3(10)x, a vertical dilation of three times is applied to the graph of y = 10x.

To create the function's graph, a horizontal shift of 2 units to the right is also used g(x) = 3(10)^x-2

Step-by-step explanation: Start by saying the question out loud in a different format:

60% of what is $54?

We know that of means multiplication and is means equals. This helps us create the equation:

60% x what= $54

Then, we need to make 60% a number we can work with by changing it into a decimal: 0.6. We also need to make 'what' something easier to use as well, so we will use x in place of what:

0.6x=54

Then, get x by itself, which is also called isolating the variable. You do this by dividing by 0.6 on both sides, which is known as using inverse operations.

You should get x=90.

This means that $54 is 60% of $90 and $90 is Noah's goal.

The standard form of a linear equation is Ax + By = C where A and B are not both zero and A, B and C are integers whose GCF is 1.

To convert the equation y = 9x - 1 to standard form, we need to rearrange it as:

9x - y = 1

We can divide both sides by -1 to get

-9x + y = -1

Which is the standard form of the equation.

So the standard form of the equation is:

-9x + y = -1
