The reduced row-echelon form of the augmented matirx of a system of equations is given. Find the solution of the system.

Answer: $654.72

Step-by-step explanation:

11 percent of $704 is $77.44  -  (11*704/100)

You do $704-$77.44 because it is on sale.

Equalling $626.56

4 percent of $704 is $28.16 - (4*704/100)

Add $28.16 to 626.56 because your being taxed.

Equalling $654.72 your answer

The total cost of the $704 tablet computer, after an 11% discount and 4% sales tax, is $651.62.

To find the total cost of the $704 tablet computer, we first need to calculate the sale price after the 11% discount. The discount amount can be found by multiplying the original price by 11% (or 0.11). So, the discount amount is $704 * 0.11 = $77.44. The sale price is then $704 - $77.44 = $626.56.

Next, we need to calculate the sales tax amount. The sales tax rate is 4%, so the tax amount is $626.56 * 0.04 = $25.06.

Finally, to find the total cost, we need to add the sale price and the sales tax amount together. Therefore, the total cost of the $704 tablet computer, including the discount and sales tax, is $626.56 + $25.06 = $651.62.

Answer:

Equations are composed for many expressions.

Expressions can indicate variables, constants, etc.

Best regards

Answer:

Step-by-step explanation:

Expressions generally contain literals and may be "evaluated" by subbing the given values of the literal into them.  Expressions may be simplified, including being rewritten in alternative forms.

Equations, on the other hand, involve the " = " symbol.  If a literal, such as x or y, is included in the equation, we can usually solve the equation for that literal, thereby creating a function.

Answer:

Which U.S. political parties would likely approve of a plan to help unemployed workers?

Step-by-step explanation:

1. Communists

2. Democrats

3. Libertarians

4. Republicans

5. Socialists

the answer is 5,3,1

Final answer:

The Libertarian Party wants little to no government interference. The Democratic and Republican parties have different stances on helping unemployed workers, taxing businesses for environmental cleanup, and providing cheaper healthcare.

Explanation:

In the United States, the Libertarian Party is a third-party that wants little to no government interference. They advocate for limited government intervention in both social and economic areas. For example, they support lower taxes, less regulation, and individual freedom.

The Democratic and Republican parties would likely approve of a plan to help unemployed workers. The Democrats often propose policies such as extending unemployment benefits and increasing job training programs, while the Republicans tend to support tax cuts and reducing government regulations to stimulate job growth.

The Democratic party is more likely to approve of a tax on businesses to clean up the environment. They generally advocate for stricter environmental regulations and support policies aimed at reducing pollution. The Republican party, on the other hand, often opposes new taxes and regulations on businesses.

The Democratic party and the Progressive wing of the Democratic party would likely approve of a plan to provide cheaper healthcare. They have been pushing for measures such as expanding Medicaid, implementing a public health insurance option, and decreasing prescription drug prices. The Republican party, however, tends to advocate for free-market solutions and reducing government involvement in healthcare.

Answer:

Smaller x   -10

Larger x     -2

Step-by-step explanation:

f(x) = (x+6) ^2 - 16

To find the zero's, we set the function equal to zero

0 =  (x+6) ^2 - 16

Add 16 to each side

16 =  (x+6) ^2 - 16 + 16

16 = (x+6)^2

Take the square root of each side

±sqrt(16) = sqrt((x+6)^2))

±4 = x+6

Subtract 6 from each side

-6±4 = x+6-6

-6±4 = x

-6 -4 = x        -6+4 =x

-10 =x                 -2 =x

Smaller x   -10

Larger x     -2

Answer:

Smaller x: -10

Larger x: -2

Step-by-step explanation:

You are looking for where the function equals 0. So, you can set f(x) equal to 0:

f(x) = [tex]0=(x+6)^{2} -16[/tex]

Now add 16 to both sides:

[tex]16=(x+6)^{2}[/tex]

Now that you have a perfect square on both sides, you can take the square root of both sides. On the right, this would simply remove the exponent. On the left, you have the square root of 16, or 4. It is important to remember that this can be positive or negative (since -4 squared also equals 16).

±4 = x + 6

To find your two solutions, you have to then evaluate the equation for 4 and -4. First, with -4:

-4 = x + 6       subtract 6 from both sides

-10 = x

Now, with 4:

4 = x + 6        subtract 6 from both sides

-2 = x

And there are your two solutions. Since -10 < -2, -10 is the smaller x and -2 is the larger one.

Step-by-step explanation:

Answer:

$291,016.80

A is correct.

Step-by-step explanation:

You are applying for an 80/20 mortgage to buy a house costing $145,000.

Loan Formula:

[tex]EMI=\dfrac{P\cdot r}{1-(1+r)^{-n}}[/tex]

Case 1:

Loan amount, P = 80% of 145000 = $ 116,000

Rate of interest, r = 4.75% = 0.0475

Time of loan, n = 30 years = 360 months

Substitute the values into formula.

[tex]EMI=\dfrac{116000\cdot \frac{0.0475}{12}}{1-(1+\frac{0.0475}{12})^{-360}}[/tex]

[tex]EMI=605.11[/tex]

Total payment for case 1: 605.11 x 360 = $217,839.60

Case 2:

Loan amount, P = 20% of 145000 = $ 29,000

Rate of interest, r = 4.75% = 0.07525

Time of loan, n = 30 years = 360 months

Substitute the values into formula.

[tex]EMI=\dfrac{29000\cdot \frac{0.07525}{12}}{1-(1+\frac{0.07525}{12})^{-360}}[/tex]

[tex]EMI=203.27[/tex]

Total payment for case 1: 203.27 x 360 = $73,177.20

Total amount of the mortgage = $217,839.60 + $73,177.20

                                                    = $291,016.80

Hence, The total amount of the mortgage is $291,016.80

Step-by-step explanation:

if a projectile is fired straight upward from the ground with an initial speed of 64 feet per second, then its height in feet after seconds is given by the function h(t)=-16t^2 + 64t. find the maximum height of the projectile.

***

h(t)=-16t^2 + 64t

complete the square

h(t)=-16(t^2 -4t+4)+64

h(t)=-16(t-2)^2+64

This is an equation of a parabola that opens upward with vertex at (2,64)

maximum height of the projectile=64 ft (2 sec after it is fired)

Answer:  in 12 years (2017)

               23,000 students enrolled

Step-by-step explanation:

Let x represent the number of years since 2005.

Let y represent the number of students enrolled.

College A: y = 14,000 + 750x

College B: y = 35,000 - 1000x

Solve the system using the Substitution Method:

14,000 + 750x = 35,000 - 1000x

           +1000x               +1000x

14,000  + 1750x = 35,000

-14,000                 -14,000

                1750x = 21,000

                        x = 12

Input x = 12 into one of the equations to solve for y.

y = 35,000 - 1000x

  = 35,000 - 1000(12)

  = 35,000 - 12,000

  = 23,000

Explanation on when two colleges will have the same enrollment and what the enrollment will be at that time.

Step 1: Set up equations for the enrollment at each college over time. Let x be the number of years since 2005:

College A enrollment = 14000 + 750x

College B enrollment = 35000 - 1000x

Step 2: Set the two equations equal to each other:

14000 + 750x = 35000 - 1000x

Step 3: Solve for x to find when the colleges will have the same enrollment:

x = 10 years

Step 4: Substitute x back into the equations to find the enrollment at each college after 10 years:

College A enrollment = 14000 + 750(10) = 21500 students

College B enrollment = 35000 - 1000(10) = 25000 students

Answer:

14

Step-by-step explanation:

Using the law of cosines on ΔRST, then

s² = 9² + 8² - (2 × 9 × 8 × cos111° )

   = 81 + 64 - ( 144 × cos111° )

   = 145 - (- 51.6)

   = 145 + 51 . 6 = 196.6 ( take the square root of both sides )

s = [tex]\sqrt{196.6}[/tex] ≈ 14

The answer is: 14

Using the law of cosines and the given information, we can find the value of s.

Law of cosines is:

[tex]a^{2}=b^{2}+c^{2}-2abcos(A)[/tex]

Where,

[tex]a=s\\b=9\\c=8\\A=111(degrees)[/tex]

By substituting we have:

[tex]s=\sqrt{9^{2}+8^{2}-2*9*8*cos(111)}\\\\s=\sqrt{81+64-(144)*(-0.35)}=\sqrt{145+50.4}=\sqrt{195.4}=13.98=14[/tex]

To determine how many apples you can buy for $168.00, you first calculate the cost per pound to be $3.50. Then, calculate that you can buy 48 pounds of apples, and since there are about 3.2 apples per pound, you can purchase approximately 153 apples for $168.00.

To determine how many apples you can buy for $168.00, let's start by calculating the cost per pound of the apples on sale, which is $28.00 for 8 pounds. This yields a cost per pound of $3.50.

Next, we'll find out how many pounds of apples you can buy for $168.00. By dividing $168.00 by the cost per pound ($3.50), we get 48 pounds of apples.

Since 1 pound equals 16 ounces, and each apple is approximately 5 ounces, we can calculate how many apples are in each pound by dividing 16 by 5, which gives us about 3.2 apples per pound.

Lastly, to find out the total number of apples you can buy for $168.00, we multiply the total pounds of apples (48) by the number of apples per pound (3.2), resulting in a total of approximately 153.6, which we can round down to 153 apples.
