100 points!
At what point(s) do these graphs intersect? y=x^2 = 3x-5
y=4x+1
Seth’s solution:
y=x^2 +3x-5
y=4x+1
x^2 =3x-5=4x+1
x^2 -x-6=0
(x-3)(x+2)=0
x=3 and x=-2
The graphs intersect at (-2,0) and (3,0).
Is Seth's solution correct? Explain.

Answers

Answer 1

Answer:

Solution is correct till finding the roots:

x = 3, x = -2

Then Seth should find the respective y- points using either equation:

y = 4*3 + 1 = 13

and

y = -2*4 + 1 = -7

Correct solution is:

(3, 13) and (-2, -7)
Answer 2

Answer:

Seth's answer is incorrect.

Step-by-step explanation:

He is correct with all of his steps until he reaches the roots... the correct roots are, y = 4(3) + 1 = 13 y = 4(-2) + 1 = -7

So the correct answer would actually be: The graphs intersect at the coordinates (3,13) and (-2,-7)

A company that teaches self-improvement seminars is holding one of its seminars in
Hampton. The company pays a flat fee of $69 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $15 to purchase
books and supplies. Each attendee will pay $18 for the seminar. Once a certain number of
attendee register, the company will be breaking even. How many attendees will that take?
What will be the company's total expenses and revenues?

Answers

Step-by-step explanation:

I take it that the $69 flat fee is for one event.

and we are talking about one event overall.

"breaking even" means that the sum of all expenses and revenues is 0.

so, with x being the number of attendees,

0 = 18x - 15x - 69

69 = 3x

x = 23

that means, with 23 attendees they will break even, and with every attendee more they will gain.

in the case of 23 attendees the company will have expenses of 69 + 23×15 = $414.

and the revenues are 23×18 = $414

Step-by-step explanation:

Simply plug -3 in for x.

-2(-3)^2-7(-3)+6

(-3)^2=9

9*-2= -18

-7*-3=21

-18+21=3

3+6=9

Answer:

f(-3) = 9

Step-by-step explanation:

Here we have a quadratic function in x:  and we want to know the value of this function when x = -3.

Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to                                                    f(-3) = -2(9) + 21 + 6, or

                                                                                    f(-3) = -18 + 27 = 9

Thus, f(-3) = 9

Answer: 5 pens cost Rs.50

Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.

using the remainder theorem which quotient has a remainder of 20?

Answers

Answer:

A

divided by (x + 4 ), then a = - 4

[tex](-4)^{4}[/tex] - 8(- 4)² + 16 = 256 - 128 + 16 = 144 ≠ 20

B

divided by (x - 2), then a = 2

C

divided by (x + 5) , then a = - 5

(- 5)³ + 5(- 5)² - 4(- 5) + 6

= - 125 + 125 + 20 + 6 = 26 ≠ 20

D

divided by (x - 2), then a = 2

The area of a rectangle is 360 cm, and the length is 2 cm more than the width Find the width​

Answers

Answer: 18 cm

Explanation:

Let x = width (W)
Let x + 2 = length (L)

Area (A) = L*W
x(x+2) = 360
x^2 + 2x = 360
x^2 + 2x - 360 = 0
(x + 20)(x - 18) = 0
x + 20 = 0
x = -20
^^^ reject because distance can’t be negative
x - 18 = 0
x = 18 (width)

x + 2 = 20 (length)

Check:
A = L*W
360 = 20 * 18
360 = 360

Although Carina wasnt an excellent runner when she first joined the team two years earlier, she practiced all the time and soon began to win almost every race in which she competed. Carina was doing so well that she thought she might become the winningest track and field athlete in her schools history! 2One afternoon at track practice, Coach Winder nabbed everyones attention to introduce a new athlete. This is Roberto," he said. "He just transferred to our school from Greensboro Middle School. Please welcome Roberto to the team! 3The members of the team clapped and jostled each other as they tried to shake Robertos hand. As the team captain, Carina shook Robertos hand first. She introduced herself and told Roberto that she was excited to have another team member. Roberto told Carina that he had been reluctant about joining the team, but Carina assured him that he would have a marvelous time. 4The next day, the members of the track team stretched before running some sprints. Carina told Roberto that he could race with her. Dont worry, she said. Ill go easy on you because its your first practice. 5Carina and Roberto lined up at the starting blocks. When they heard the CRACK of the starting pistol, Roberto and Carina started. After a short distance, Carina realized that Roberto was no longer beside her. She turned to see how far behind he had fallen, but to her amazement, Roberto was not behind her. She looked up and saw Roberto surging ahead. His feet moved as fast as lightning! When Carina realized that she was about to lose, she ran as vigorously as she could; however, it wasnt enough. Roberto triumphed. Carina seemed almost paralyzed with shock, but she managed to smile and congratulate him. 6Over the next few weeks, Roberto became a phenomenon on the track. No matter how hard Carina trained, she could never beat Roberto. 7One evening after a track meet, Carina was desolate. Roberto had won first place, and Carina had come in third! She considered hanging up her running shoes and quitting the team. Just as she was about to call Coach Winder, her father entered the living room. Carina explained her situation to him. 8If winning is so important to you that you cant merely have fun being a member of the team, said Carinas father, then I guess quitting is your only option. But, before you make your decision, think about why you originally joined the team. 9The next day, Carina walked into Coach Winders office and handed him a slip of paper. Coach Winders eyes widened as he read it. Then, he closed the note and shook his head approvingly. 11Thats right, Carina said with a smile, Id like Roberto to serve as co-captain of the team.What happens in the RESOLUTION of this story?
