Answer:

option B

Step-by-step explanation:

Given : A parallelogram ABCD

To find : Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?

Since forming the reflected image follows Every point on the image will be the same distance as its corresponding point from the pre-image.

This distance will be perpendicular to the line of reflection i.e. dashed line

And the second option shows the correct image .

In the second image the perpendicular was draw along the axis of reflection .

Hence the option B is correct .

The second image shows a method for reflecting through this line.

Every point on the image will be the same distance as its corresponding point from the pre-image. This distance will be perpendicular to the line of reflection. The second image shows this process.

If x and y vary inversely and x = 5 when y = -3.5, what is the value of x when y = 10?

Solnce55 [7]

Answer:

Step-by-step explanation:

k = xy

Putting values of x and y in the equation

k = (5)(-3.5)

= - 17.5

Finding value of x when y = 10

k = xy

- 17.5 = x10

Bringing like terms on one side

- 17.5 - 10 = x

-27.5 = x

k0ka [10]

Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

$log_{10}(y) = 2.447$

In order to find the value for y, one must simply apply the following logarithmic property:

if : $log_{b}(a) = c$

then: $b^c = a$

Applying it to this particular problem:

$log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280$

Therefore, the regression line predicts y will equal 280 when x equals 5.

Describe a relationship in which it would be reasonable to have a negative number in the domain or

Aliun [14]

Answer:

Relationship between temperature at different times of the day during the Winter period in places like Alaska and Minnesota in the USA.

Step-by-step explanation:

An example of a relationship that would have a negative number in the domain or range would be the relationship between the temperature at different times of the day during the snow period in the winter. It's well known that in places like Alaska and Minnesota in the USA, that during the winter when there's very heavy snow, the average temperature is usually below 0°C. The temperature is the dependent variable and is most likely negative in those 2 states and thus the range would have negative numbers.
