A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8

y = -6x + 20

Explain why the work is not correct.

Answers

Answer 1

Answer:

The student should subtract 8 from each side not add 8

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y - -8 = -6(x -2)

y+8 = -6(x-2)

Distribute

y+8 = -6x+12

Subtract 8 from each side

y+8-8 = -6x+12-8

y = -6x+4

The student should subtract 8 from each side not add 8

Answer 2

Answer:

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side

y = -6x + 20

the correct equation would be : y= -6x+4

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans. She took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. Approximately how much more in interest over the life of the loan does Nellie have to pay? a. $68,510.16 b. $53,696.16 c. $32,206.32 d. $14,814.00

Answers

Using simple interest, it is found that she has to pay $24,300 more in interest.

The amount of money after t years, in simple interest, is given by:

[tex]A(t) = P(1 + kt)[/tex]

In which:

P is the principal.k is the interest rate, as a decimal.t is the time, in years.

In this problem:

Loan of $45,000, thus [tex]P = 45000[/tex].6 years, thus [tex]t = 6[/tex].

The amount with 15% interest is:

Here, [tex]k = 0.15[/tex]

[tex]A(6) = 45000[1 + 0.15(6)] = 85,500[/tex]

The amount with 6% interest is:

Here [tex]k = 0.06[/tex].

[tex]A(6) = 45000[1 + 0.06(6)] = 61,200[/tex]

The difference is:

85,500 - 61,200 = 24,300

She has to pay $24,300 more in interest.

Answer:

I cracked the code on my journey to find the correct answer to this problem

The answer is D or $14,814.00

Step-by-step explanation:

This is more than simple interest, this is something to do with amortization

this is a monthly payment calculator for a car loan

[tex]A=p\cdot\frac{\left(r\left(r+1\right)^{n}\right)}{\left(\left(1+r\right)^{n}-1\right)}\\[/tex]

This isn't exactly what we are looking for since we aren't looking for monthly payments but this can still help.

So our variables are [tex]p=45,000[/tex], where p is for principle

r is the loan rate in monthly terms or divide the interest by 12 which is [tex]r=0.0125[/tex] for when 15% is interest and [tex]r=0.0005[/tex] when 6% is interest.

and n is years times 12 or monthly periods involved so [tex]n=72[/tex]

so our equation is [tex]45000\cdot\frac{\left(0.00125\left(0.00125+1\right)^{72}\right)}{\left(\left(1+0.00125\right)^{72}-1\right)}[/tex]

which is equal to 951.53

This number is our monthly payment

so for the full cost is [tex]951.53*12*6[/tex]

that equals 68510.16

now for when interest is equal to 6%

[tex]45000\cdot\frac{\left(0.0005\left(0.0005+1\right)^{72}\right)}{\left(\left(1+0.0005\right)^{72}-1\right)}[/tex]

this is equal to [tex]745.78*12*6[/tex]

so for the full cost is

so the extra interest is equal to the larger number minus the smaller one

[tex]68510.16-53696.16[/tex]

which equals

14,814.00 exactly

Mrs. Jones decided to buy some pencils for her class. She bought 4 packages of pencils, and each package contained 57 pencils. There are 19 students in her class and she divided up the pencils so that each student had the same amount of pencils. If there were no pencils left over, how many pencils did each student get?

Answers

Answer:

The correct answer is 19 pencils.

Step-by-step explanation:

First, we have to multiply

57 x 4 = 228

Second, we have to divide

228 ÷ 19 = 12

Lastly, we write the answer in a complete sentence.

Each student got 19 pencils if there were no pencils left over.

Hope This Helps!

Answer:

Each student got 12 pencils

The school that Jenny goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 14 adult tickets and 14 child tickets for a total of $322. The school took in $188 on the second day by selling 12 adult tickets and 1 child ticket. What is the price of each of one adult ticket and one child ticket?A. Adult Tickets: $17, Child Ticket: $12B. Adult Tickets: $15, Child Ticket: $8C. Adult Tickets: $9, Child Ticket: $3D. Adult Tickets: $24, Child Ticket: $13

Answers

The price of one adult ticket is $15 and the price of one child ticket is $8.

Two sets of equations can be derived from this question:

14a + 14c = 322 equation 1

12a + c = 188 equation 2

These equations are known as simultaneous equations and they can be solved to determine the cost of each ticket using the elimination method.

In order to determine the cost of the adult's ticket multiply equation 2 by 14

168a + 14c = 2632 equation 3

Subtract equation 1 from 3

2310 = 154a

Divide both sides by 154

a = $15

To determine the cost of the children's ticket substitute for a in equation 1

14(15) + 14c = 322

210 + 14c = 322

322 - 210 = 14c

112 = 14c

c = $8

Use the figure to find the measures of the numbered angle.

Answers

Answer:

angle 1 = 61°

angle 2 = 119°

angle 3 = 61°

angle 4 = 119°

angle 5 = 119°

angle 6 = 61°

angle 7 = 119°

Step-by-step explanation:

angle 1 = 61° (corresponding angles are always equal)

angle 1 + angle 2 = 180° (linear pair)

=> 61° + angle 2 = 180°

=> angle 2 = 180° - 61° = 119°

angle 2 = 119

angle 1 = angle 3 = 61° (vertically opposite angles are equal)

angle 2 = angle 4 = 119° (vertically opposite angle are equal)

angle 4 = angle 5 = 119° (interior opposite angles are equal)

angle 6 = 61° (vertically opposite angles are equal)

angle 5 = angle 7 = 119° (vertically opposite angles are equal)
