Viola can work no more than 11 hours a week at her part-time job. she gets paid $7.75 per hour. let p stand for the amount she gets paid for h hours. what domain and range are reasonable for this situation?

Step-by-step explanation:

To find the right domain and range, we just have to express each set with the proper values for each variable.

So, if Viola can work no more than 11 hours, this means that she can only work 11 hours or less, that would expressed like this:

This means that the domain goes from 0 hours to 11 hours, which is the most logical set for the domain according to the given restriction.

Now, the range must represent the money she could make according to this domain. We know that she gets $7.75 per hours. If she works 0 hours, she gets $0, if she works 11 hours (which is the max), she gets $7.75(11)=$85.25.

This means that the range goes from $0 to $85.25, which is expressed like this:

Therefore, the correct choice is D, because it shows the right sets for the domain and range.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
