18 Which expression is a factored form of 2x2 - 25x + 63?
O (X+9)(2x+7)
O (X - 9)(2x - 7)
O (X+7)(2X+9)
O (X - 7)(2x - 9)

Answer:

See below.

Step-by-step explanation:

[tex]\frac{1}{12} +\frac{1}{6} = \frac{2 + 1}{12} = \frac{1}{4}[/tex]

[tex]\frac{1}{4} - \frac{1}{8}=\frac{2-1}{8} = \frac{1}{8}[/tex]

[tex]\frac{2}{3} +\frac{1}{3} = 1[/tex]

[tex]\frac{1}{2} - \frac{1}{6} = \frac{3-1}{6} = \frac{1}{3}[/tex]

Answer:

1/12 + 16 = 1/4

1/4 - 1/8 = 1/8

2/3 + 1/3 = 1

1/2 - 1/6 = 1/3

Step-by-step explanation:

1/12 + 1/6

LCM of denominators 12 and 6 = 12

1/6

Multiply 2 to both numerator and denominator,

1/6 * 2/2

= ( 1*2 )/( 6*2 )

= 2/12

1/12 + 1/6

= 1/12 + 2/12

= ( 1 + 2 )/12

= 3/12

12 = 3*4

3/12

= 3/( 3*4 )

= 1/4

1/4 - 1/8

LCM of denominators 4 and 8 = 8

1/4

Multiply 2 to both numerator and denominator,

1/4 * 2/2

= ( 1*2 )/( 4*2 )

= 2/8

1/4 - 1/8

= 2/8 - 1/8

= ( 2 - 1 )/8

= 1/8

2/3 + 1/3

= ( 2 + 1 )/3

= 3/3

= 1

1/2 - 1/6

LCM of denominators 2 and 6 = 6

1/2

Multiply 3 to both numerator and denominator,

1/2 * 3/3

= ( 1*3 )/( 2*3 )

= 3/6

1/2 - 1/6

= 3/6 - 1/6

= ( 3 - 1 )/6

= 2/6

6 = 2*3

2/6

= 2/( 2*3 )

= 1/3

Answer:

5x-18

Step-by-step explanation:

18 less than the product of 5 and a number.

The product of 5 and a number is equal to 5x.

You then subtract 18 from the product and you get 5x-18

Answer:

5x-18

Step-by-step explanation:

For a standard,  year $16000 home/car loan 7.25% APR with payments due at the end of the month, calculate the monthly payment:

Calculate Months:

Your loan term is for years.

Months = 12 * Years

Months = 12 *

Months = 0

Now calculate monthly Annual Percentage Rate (APR):

APR  =   Annual APR

  12

APR  =   7.25

  12

 APR  =  0.0060416666666667 <----- This is the effective interest each month.

Now calculate Annual Percentage Yield (APY):

APY = ((1+APR)12 - 1) * 100%

APY = ((1 + 0.0060416666666667)12 - 1) * 100%

APY = ((1.0060416666667)12 - 1) * 100%

APY = (1.0749582974213 - 1) * 100%

APY = 0.074958297421329 * 100%

APY = 7.5% <----- What you actually pay in interest with monthly compounding.

Calculate our monthly loan payment:

Monthly Payment  =   Loan Amt * APR

  1 - (1/(1 + APR))n

Monthly Payment  =   16000 * 0.0060416666666667

  (1 - (1 /(1 + 0.0060416666666667))0

Monthly Payment  =   96.666666666667

  (1 - (1 / 1.0060416666667)0

Monthly Payment  =   96.666666666667

  1 - 0.99399461586250

Monthly Payment  =   96.666666666667

  1 - 1

Monthly Payment  =   96.666666666667

  0

Monthly Payment = 0

Now calculate the total number of payments you will make:

Total Payments = Monthly Payment * Months in the Loan

Total Payments = 0 * 0

Total Payments = $0.00

You will end up paying $0.00 - $16,000.00 = $-16,000.00 above the principal on this loan.

Answer:

Step-by-step explanation:

3y=6x+3

solve by substitution for 3y=6x+3

3y=4x+6

Answer:

i) True

ii) True

Step-by-step explanation:

Given :-

Point (-1, 2)

To Find :

Whether the point is a solution of :

Solving :-

Substitute the value of the point in each of the equations.

=> y = -2x

=> 2 = -2(-1)

=> 2 = 2 [∴ The point makes it true]

=> y = x + 3

=> 2 = -1 + 3

=> 2 =  2 [∴ The point makes it true]

Answer:

true

Step-by-step explanation:

first, you take the y = -2x and plug that into y = x + 3. so your equation should be -2x = x + 3. you then solve for x which comes out to be -1. you then plug the -1 into y = -2x. your equation should be y = -2(-1). solve for y which equals 2. the point that you got from both equations matches the point from the equation given so it is true.

Answer:

Step-by-step explanation:

Hope this helps! sorry was a tad bit late

It took 2 hours and 15 minutes to repair the car.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given that,

Total bill for the repair of car = $357

Let's say it took x hour to repair the car

So,

32x will be the labor cost

Now,

Labor cost + cost of parts = total bill

So,

32x + 285 = 357

32x = 72 ⇒ x = 2.25 hour

Now,

0.25 hour in minutes ⇒ 0.25 × 60 = 15 minutes.

Hence "It took 2 hours and 15 minutes to repair the car".

Answer:

C) 3^3*x^-3

Step-by-step explanation:

okay, so let's just find the numerator and denominator separately

So 27 is equal to 3^3. Numerator done.

Now for the denominator:

You need to know the laws of indices, specifically the one which says that square root of something is the same as to the power of 1/2, where the 1 signifies the power of the number inside the root and the 2 is for the square root. This means that the cube root would be power of 1/3.

So here cube root of x^9, would be equivalent to x^9/3, which can be simplified to x^3/1 ---> x^3.

This leaves us with 3^3/x^3. However, this isn't an option. We need to simplify the divide part of the expression. We can do that by using another law of indices which states that anything to the power of a negative number is the same as 1 over that number. (For example, x^-5 = 1/x^5) If there are numbers in front of the x, then that number would replace the 1, such as the following example: 9x^-3 = 9/x^3.

In this question, our 3^3/x^3 could be changed using this law to give, 3^3*x^-3

I hope this made sense and was helpful :))
