4. Write an equation of the vertical line that passes through the point (-2,-8)

Answers

Answer 1
X=-2
You can know this because when you have only an x value you graph it by drawing a line straight up from there because there is every possible y value.

y = [ ? ]x + [ ]

Answers

Answer:

  y = 4x -14

Step-by-step explanation:

The required answer form is slope-intercept form, so we need the slope and the y-intercept of the line.

The slope equation is ...

  m = (y2 -y1)/(x2 -x1)

  m = (10 -2)/(6 -4) = 8/2 = 4

The y-intercept equation is ...

  b = y - mx

  b = 2 -4(4) = -14

The equation of the line is y = 4x -14.

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $17. For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $23. Find the cost for each pound of trail mix and each pound of jelly beans.

Answers

Answer:

Trail Mix costs $2.50 per pound, and Jelly Beans cost $1.50 per pound.

Step-by-step explanation:

Using x for trail mix and y for jelly beans, we have a system of equations being

[tex]\left \{ {{5x+3y=17} \atop {2x+12y=23}} \right.[/tex]

We can solve this system using substitution

5x+3y=17

Divide by 5 to have a coefficient of 1 before x

[tex]x+\frac{3}{5} y=\frac{17}{5}[/tex]

Subtract [tex]\frac{3}{5} y[/tex] from each side to single out one variable to one side

[tex]x=\frac{17}{5} -\frac{3}{5} y[/tex]

Now, we can plug in our value for x into the given equation

[tex]2(\frac{17}{5} -\frac{3}{5} y)+12y=23[/tex]

Open the parentheses

[tex]\frac{34}{5} -1\frac{1}{5} y+12y=23[/tex]

Merge Y values

[tex]6.8+10.8y=23[/tex]

Separate numerical values from variables

[tex]10.8y=16.2[/tex]

Divide by 10.8 in order to have a coefficient of 1

[tex]y=1.5[/tex]

Now that we have one of the values, we know that a pound of jelly beans costs $1.50. We can now plug in 1.5 for y into one of our equations to find x.

[tex]5x+3(1.5)=17[/tex]

Open parentheses

[tex]5x+4.5=17[/tex]

Single out the variable

[tex]5x=12.5[/tex]

Divide by 5 to have a coefficient of 1 before x

[tex]x=2.5[/tex]

[tex]y=1.5[/tex]

Answer:

Option 4: (0, 5]

Step-by-step explanation:

Given the inequality notation, 0 < x ≤ 5 :

Definitions:open- and closed-parenthesis "(  )"

We know that using the open- and closed-parenthesis, "(  )" are used to express interval notation for which the endpoints are not included as part of the solution.  Hence, the open- and closed-parenthesis are associated with the inequality symbols, less than (>) or greater than (<), as you do not include the endpoints when these inequality symbols are used.

open- and closed-brackets "[     ]"

In contrast, the open- and closed-brackets, "[     ]" are used to express interval notation for which the endpoints are included as part of the solution.  Hence, the open- and closed-parenthesis are associated with the inequality symbols, less than or equal to (), and greater than or equal to ().

Explanation:

In the inequality notation, 0 < x ≤ 5, the endpoints are 0 and 5.  

The inequality symbol between 0 and x is "<," which means that we must use an open parenthesis, " ( " for the endpoint, 0.

While the inequality symbol between x and 5 is "," which means that we must use an closed bracket, " ] " for the endpoint, 5.

Therefore, the correct answer is Option 4: (0, 5].

Please answer: The Maxwell children have hired a caterer to provide food for an anniversary party for their parents. The caterer has quoted a price of $96 per person and is asking for an advance payment of one-fourth of the total bill. If the advance payment is $1200, how many guests are invited to the party?

Answers

In the exercise Maxwell children want to calculate the estimated amount or budget placed on one person coming to the  anniversary party for their parents.

The number if guest will be 50 guests

Given data

quoted price = $96 per person

Let the total bill be x

one-fourth of the total bill = 1/4*x

advance payment is $1200 = 1/4x------------1

Let us find the total bill which is x

$1200 = 1/4x

cross multiply

1200*4 = x

x = 4800

if the budget per person is $96

Hence the total expected guest will be = 4800/96

50 guests

The vertical intercepts is

The horinzontial intercepts is

(0,72)

Step-by-step explanation:

The vertical or y intercepts will be zeroes of the following factors.

3x+4=0

x-1=0

(x-3)^2=0

We solve for x each time

x=-4/3

x=1

x=3

Part B). We need to find the intercepts by setting the equation equal to zero.

The constant expanded will equal 72.

If x=0,

0y=0

where y is any real number.

So this means all the exponets will equal 0. The constant will just add to the term. so our horinzontal intercept is

He was busy texting Vince Cordova about a new show they were planning to binge watch Friday night.Seo. . . . Seo!What?What do you mean, 'What? I need you to chop the scallions. It was 11:30 a.m., and the Town Pavilionthe office building Ji-Suk's food truck Bul-GO!-gi was parked outside ofwas about to unleash a stampede of customers. I have to get this beef marinating, otherwise in a half hour I'm going to lose a bunch of hungry tax consultants to the chicken and waffle guys across street.Seo-Jun smiled, but Ji-Suk couldn't see his eyes from under his royal blue cap. Then she realized he was still looking at his phone, which he was concealing below his knees as his fingers tapped the screen.Hey! She threw a kitchen towel at him, and it unfurled in midair and landed on his head, draping itself over the brim of his cap.Okay, okay, I'll do it.Ji-Suk had made a name for herself in Kansas City, especially after a local magazine wrote a big cover story when she left her job as an attorney at a law firm after seven years to start a food truck business. If her own mother had still been alive, she would have been quite upset with Ji-Suk for that. Her mother had spent years learning to speak relatively good English, and shed been determined to make sure Ji-Suk graduated from a respectable college and became a lawyer. Even though she'd made Ji-Suk take Korean lessons every Saturday morning followed by violin lessons in the afternoonand cooked kimchi and other Korean delicacies with her at least once a weekJi-Suk's mother had wanted her to succeed by American standards. And she had. She'd become a lawyer, just like her mother wanted, but she'd also learned to love burnt end barbecue, a local culinary favorite. She was an avid fan of the Kansas City Chiefs. She even loved playing softball; she had a wickedly fast windmill pitch, having played throughout college and graduate school and on the law firm's recreational team. Ji-Suk had succeeded by American standards in ways her mother couldn't have imagined, and in ways her mother probably didn't want, but Ji-Suk couldn't do anything about that. She was American, just as much as she was Korean, and even though her mother wouldn't have wanted her to do it, starting the food truck was Ji-Suk's way of honoring her mother and showing that she valued what her mother had taught her.Still, she was determined not to force Seo-Jun to do the things her mother had forced her to do. He wouldn't have to take violin lessons, nor would he have to learn Korean. She was more than willing to let him take Korean lessons if he showed any interest, but he never did.She wasn't sure, however, whether she was doing the right thing, as Seo-Jun didn't seem to want to play sports, nor did he have any serious hobbies. He got by in school, but he didnt apply himself. He was mostly interested in his friends. She hadn't been any different at his age, and she would have spent most of her time with her friends, too, but her mother would never have allowed it.Seo-Jun finished chopping a stalk of scallions and put down his knife in order to glance at his phone. Hey mom, Vince has to do something with his family on Friday night. He asked if we can hang out right now. Would it be okay if I headed over there now?Sure.He tried to read his mother's face, but she just carried on marinating the meat. He grabbed his backpack and threw it over one of his shoulders. Then he headed out the back door of the truck.He looked back at her serving her first guest. She was smiling, but it was a distant smile. Without saying a word, he climbed back into the food truck.Ji-Suk glanced over but still didn't say a word.He picked up his knife and a handful of scallions and started chopping.Which sentence best summarizes a theme of "Bul_GO!-gi"?Children are never exactly the same as their parents.Parents cannot control their childs decisions.One must find a balance between time with family and friends.Every generation has to find its own way to be unique and still honor its heritage.
