What rule changes the input numbers to output numbers?

1 answer:

8 0

Y - (-6) = (-4 - (-6))/(2 - 1) (x - 1)
y + 6 = (-4 + 6)(x - 1)
y + 6 = 2(x - 1) = 2x - 2
y = 2x - 2 - 6 = 2x - 8
y = 2x - 8.

option b is the correct answer.

The graph of a linear function is given below.

hoa [83]

The zero of the linear function is -2

<h3>How to determine the zero of the function?</h3>

This is the point where the line of the equation crosses the x-axis

From the attached figure, the line cross the graph at:

x = -2

Hence, the zero of the function is -2

A restaurant decides to test their oven's thermostat to see if it is working properly, that is, if the actual temperature inside

Taya2010 [7]

Answer:

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

With n = 20 and represent the mean temperature of the oven

The correct option for this case is:

mu = the true mean temperature of the oven xbar = the true mean temperature of the oven

Step-by-step explanation:

Previous concepts

Parameter represent a property of a population and is calculated with the information of all the populatio. Some examples are the population mean and deviation $\mu,\sigma$

Statistic represent a propoerty of a sample and are used used in order to describe the population parameters, since represent estimators of the real parameters.

Solution to the problem

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2

vladimir2022 [97]

Answer:

$y-2 = -3(x-2)$

Step-by-step explanation:

Find the diagram to the question attached.

The standard equation of a line in point-slope form is expressed as:

$y-y_0 = m(x-x_0)$ where:

m is the slope of the line

$(x_0, y_0)$ is coordinate point on the line

First is to get the slope of the line.

$m = \frac{y_2-y_1}{x_2-x_1}$

If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)

$m = \frac{8-2}{0-2}\\m = \frac{6}{-2}\\m = -3$
