Answer:

Option c

Step-by-step explanation:

Given : Marcus suggests that figure A was reflected over the y-axis and then translated 2 to the right and 1 up. Julianne agrees and states that the transformations could happen in any order.

Solution :

If we shift according to the Marcus then we get the correct figure refer the attached figure (Marcus case)

Julianne agrees and states that the transformations could happen in any order.

Option c : Inaccurate. A translation of 2 to the right and 1 up and then a reflection over the y-axis results in a figure that is located in the second quadrant.

This best describes the accuracy of Julianne’s statement

Refer the attached file which shows the figure according to option c

in option c the order is not followed so the resultant figure is incorrect .

F(x) = x^2 – (x + 3), what is the value of f(8)

eimsori [14]

Answer:

53

Step-by-step explanation:

f(x) = x^2 – (x + 3)

Let x = 8

f(8) = 8^2 – (8 + 3)

=64 - (11)

=53

Nikki gathered data about the length of time she spent listening to the radio and the number of commercials she heard. She organ

topjm [15]

Answer:

The number of minutes Nikki needs to listen to the radio to hear 20 commercials is 63.275 minutes

Step-by-step explanation:

The given dependent and independent variables are;

The number of minutes spent by Nikki listening = x

The number of commercials aired = y

The relationship between the independent variable, x ans the dependent variable, y, was given by the Nikki's graphing tool line of best fit as follows;

y = 0.338·x - 1.387

Therefore, the number of minutes, x, Nikki needs to listen to the radio to hear 20 commercials, y is given as follows;

20 = 0.338·x - 1.387

20 + 1.387 = 0.338·x

0.338·x =20 + 1.387 = 21.387

x = 21.387/0.338 = 63.275 minutes

The number of minutes, x, Nikki needs to listen to the radio to hear 20 commercials, y = 63.275 minutes.

For all integer values of x and constant k, if (x-k)(x-5)=x^2-9x+20, what is the value of K?

amid [387]

<h3>Answer: C) 4</h3>

============================

Work Shown:

Expand out the left hand side

(x-k)(x-5)

x(x-5)-k(x-5)

x^2-5x-kx+5k

Note that the constant term here is 5k. Yes k seems like a variable, but it's actually a constant. Once we know k, we can replace it to get a fixed number. In this case, k = 4 since 5k = 5*4 = 20 to have it match with the 20 at the end of x^2-9x+20

For the x terms, we have -5x-kx = -5x-4x = -9x which matches with the middle term of x^2-9x+20

Therefore,

(x-k)(x-5) = x^2-9x+20

updates to

(x-4)(x-5) = x^2-9x+20

The -4 and -5 multiply to 20, and they also add to -9. This helps confirm we have the right k value.
