Emma and her children went into a restaurant where they sell hotdogs for $4 each and drinks for $1.50 each. Emma has $30 to spend and must buy no less than 9 hotdogs and drinks altogether. If xx represents the number of hotdogs purchased and yy represents the number of drinks purchased, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer 1

Answer:

6 hotdogs and 4 drinks

Step-by-step explanation:

4x + 1.50y = 30

For questions like this, you can do the equation that represents the price of the products first.

x + y  [tex]\geq[/tex] 9

After that, you can write the equation that represents the quantities.

Now, you just have to graph it to find the solution. When you're graphing, make sure that y is alone on one side. Here's how you rearrange the equations:

The first equation:

4x + 1.50y =30

*Subtract 4x from both sides, which leads to:

1.50 y = -4x + 30

*Divide by 1.50 on both sides, which leads to:

y = -2.66x + 20

The second equation:

x + y  [tex]\geq[/tex] 9

*Subtract x from both sides, which leads to:

y  [tex]\geq[/tex] -1x + 9

Now, use any graphing calculator (I prefer Desmos) to graph these two equations. In fact, you can just graph it on paper, too.

Here is the graph: (it is attached as a file)

You can look for any points that are on the red line but are also shaded blue. Make sure you look only in Quadrant 1- don't go into the negatives! One good point to choose would be (6,4)- this means that you buy 6 hotdogs and 4 drinks.

A shirt is regularly priced at 42$. It is on sale for 15% off of the regular price. What is the sale price of the shirt ?

Answers

Answer:

$35.7

Step-by-step explanation:

you can convert 15% to a decimal by dividing by 100.

15/100 = .15

if you multiply the decimal by the cost of the shirt you get how much the discount is.

0.15 * $42 = 6.30

so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.

$42 - $6.30 = $35.70 that is the sale price of the shirt.

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you would reflect over y=0. Whenever you reflect over y=0, the y-coordinate will be multiplied by -1, so it changes to (1,-2). (1,-2) is 4 coordinates below the line y=2, so when reflected over y=2, the coordinate will be 4 above y=2, which means that the coordinate will be (1,6)

2. The velocity of an object in motion is given by the function y(t)=-78.4t + 288 where vt is the velocity of the object in meters per second at time t.

B. After how many seconds does the object momentarily come to rest and then change directions?​

Answers

Answer:

t = 3.7 seconds

Step-by-step explanation:

Linear Modeling

The velocity of an object is modeled by the function

v(t) = -78.4t + 288

Where v is expressed in m/s and t is expressed in seconds.

The velocity is a vector, therefore its sign indicates its direction. If the object is at rest, then its velocity has a magnitude of zero.

To find when the object comes to rest, we set the velocity to 0:

-78.4t + 288 = 0

Now solve for t. Subtracting 288:

-78.4t = -288

Dividing by -78.4:

t = -288 / -78.4

t = 3.7 seconds

A video game has the following formula: For every 1,333 in attack power, you gain 3 levels. You get one bonus star per every 38 levels completed. If a player has an attack power of 0.21 million, how many bonus stars could they get? Round to a whole number.

Answers

Answer:

Rounded to a whole number, the player has 12 bonus stars.

Step-by-step explanation:

Since the video game establishes that for every 1,333 points of attack power 3 levels are gained, and that the player has a total of 0.21 million attack points, to determine the number of levels that player has it is necessary to perform the following calculation :

0.21 million = 210,000

210,000 / 1,333 x 3 = Levels

472.6 = Levels

Now, every 38 levels, the game awards a bonus star. To determine the amount of bonus stars that the player has, the following division must be made:

472.6 / 38 = X

12.43 = X

Thus, rounded to a whole number, the player has 12 bonus stars.

Find the distance between A and B . For the past week, Christopher has been studying for his first American History exam. Christopher plans to transfer and eventually become a pre-law major, so his success in this course is very important to him. He has taken a number of steps to make sure he is preparedfor example, he met up with friends from class to review their notes as a group, he added in extra study time instead of attending his usual workouts at the gym, and he made sure to eat healthy meals and avoid drinking too much coffee. When he woke up after a full night's sleep the morning of the test, he reassured himself that he had put in a lot of effort and he would do well. On the day of the test, Christopher attempted to calm his nerves, looked over the entire exam, and made a plan to answer the easiest multiple-choice questions first. When it came time to write the essay portion of the exam, he created a short outline of what he wanted to say, though he acknowledges that he didn't always stick to his main points. He ended up writing more than he anticipated (almost two full pages) because he wanted to share everything he knew about the topic. Christopher admits that he guessed at some of the items on the multiple-choice part of the exam. He felt sure he had done well on the essay, but he scored only 30 out of the 50 possible points. Overall, Christopher received a grade of 63 out of 100 points on the exam.Which of the following might have negatively impacted Christopher's test preparation? In the week leading up to the exam, Christopher skipped his regular workouts, replacing them with extra study sessions. He chose to get a good night's sleep the night before instead of staying up to cram. He joined a study group instead of studying independently. He used positive self-talk, which likely gave him a false sense of security. 2. What could have gone wrong during the exam? He took time at the beginning of class to survey the entire exam. He answered the easy questions first. He developed a brief outline of his essay before beginning to write. For the essay, he provided all the information he knew on the topic, resulting in a lengthy two-page answer. 3. What strategy should Christopher NOT employ when preparing for the next exam? Ask his instructor about the test. Ignore his other class assignments the week leading up to the exam so he can spend multiple hours a day studying. Manage his exam preparation time wisely. Focus his study. 4. If Christopher finds himself becoming anxious about his next exam, which strategy should he use to manage any feelings of test anxiety? Sit with a rigid, tense posture to stay awake and alert throughout the test. Ignore his anxious thoughts as much as possible and use negative mental messages to keep himself on-task. Breathe deeply to help himself stay calm and think clearly. Avoid eating breakfast the morning before the test to diminish feelings of anxiety-related nausea. 5.
