Step-by-step explanation:

If (5, - 4) is a solution to the system then both equations will be true when (5, - 4) is substituted into them.

Substitute (5, - 4) into the left side of the equations and if equal to the right side then (5, - 4) is a solution.

3(5) - 2(- 4) = 15 + 8 = 23 = right side

2(5) + (- 4) = 10 - 4 = 6 = right side

Then (5, - 4) is a solution to the system of equations.

or by solving

3x - 2y = 23 → (1)

2x + y = 6 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

4x + 2y = 12 → (3)

Add (1) and (3) term by term to eliminate y, that is

7x = 35 ( divide both sides by 7 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

2(5) + y = 6

10 + y = 6 ( subtract 10 from both sides )

y = - 4

Solution is (5, - 4 )

Using the concept of simultaneous equation, the solution to the system of equations is (5, - 4)

Given the system of linear equations :

From (2) :

Substitute (3) into (1)

3x - 2(6 - 2x) = 23

3x - 12 + 4x = 23

7x = 23 + 12

7x = 35

Divide both sides by 7 to isolate x

x = 35 / 7

x = 5

From (3)

y = 6 - 2(5)

y = 6 - 10

y = -4

Therefore, the solution to the system of equation is (5, - 4)

Answer:

  $475

Step-by-step explanation:

The total amount Rahim will be paying is found from the simple interest formula ...

  A = P(1 +rt) . . . . . P is the loan amount, r is the annual rate, t is the number of years.

  A = $24,000(1 +0.0375×5) = $28,500

Spread over 60 monthly payments, that amounts to ...

  $28,500/60 = $475 . . . per month

__

Additional comment

Mr. Rahim's loan has an APR of 6.98%. This sort of loan costs more than the interest rate might suggest, because interest is still being paid on principal that has already been repaid.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches ([tex]1\,ft = 12\,in[/tex]) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

[tex]l = 120\,ft[/tex] ([tex]l[/tex] - Length)

[tex]l = 120\,ft\times \frac{12\,in}{1\,ft}[/tex]

[tex]l = 1440\,in[/tex]

[tex]w = 75\,ft[/tex] ([tex]w[/tex] - Width)

[tex]w = 75\,ft\times \frac{12\,in}{1\,ft}[/tex]

[tex]w = 900\,in[/tex]

Step 2 - Applying scaling:

[tex]l' = \frac{l}{180}[/tex] ([tex]l'[/tex] - Scaled length)

[tex]l' = \frac{1440\,in}{180}[/tex]

[tex]l' = 8\,in[/tex]

[tex]w' = \frac{w}{180}[/tex] ([tex]w'[/tex] - Scaled width)

[tex]w' = \frac{900\,in}{180}[/tex]

[tex]w' = 5\,in[/tex]

Step-by-step explanation:

Given;

total number of boxes of doughnuts sold, T = 15 boxes

the cost of each box of doughnuts, C = $4

The total cost of the doughnuts sold = 4 x 15 =  $60

The only option that contains pair of expressions that is equal to $60 is option D.

(D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15

(10 × 4) + (5 × 4) = 40 + 20 = $60

15 + 15 + 15 + 15 = $60

A man by the name of Luigi Fonti wrote this. I hope it can guide you, as it did for me! "The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational."

Answer:

x = 22

Step-by-step explanation:

Knowing that it a supplementary angle = 180 degree

It a right angle therefore it makes that 90 degree

Thus,

The 2 equation is

4x + 2 = 90

3x + 24 = 90

Let first solve this one

4x + 2 = 90

Subtract 2 from both sides

4x + 2 - 2= 90-2

Simplify

4x = 88

Divide both sides by the same factor

4x/4 = 88/4

Simplify

x = 22

Now the second equation:

3x + 24 = 90

Subtract 24 from both sides

3x + 24 - 24 = 90 -24

Simplify

3x = 66

Divide both sides by the same factor

3x/3 = 66/3

Simplify

x = 22

Hence, x = 22.

Points which lie on the line

(6, 2)

(5, -3)

(7, 7)

Answer:

(6, 2 )

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y - 2 = 5(x - 6) ← is in point- slope form

with (a, b ) = (6, 2 )

then (6, 2 ) is a point on the line
