The system of equations, -x + y = -2 and 2x - 2y = 0, has no solution.

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

Given two equations in x and y,

-x + y = -2     (equation 1)

2x - 2y = 0     (equation 2)

Rewrite equation 1 as an equation of y and substitute to equation 2.

(equation 1) -x + y = -2     ⇒     y = x - 2

2x - 2y = 0     (equation 2)

2x - 2(x - 2) = 0

2x - 2x + 4 = 0

4 = 0

Since we do not have a definite value for x, and neither will be for y, the system of equation has no solution.

Checking the slope,

(equation 1) -x + y = -2     ⇒     y = x - 2

m = 1

(equation 2) 2x - 2y = 0     ⇒     y = x

m = 1

Since the two equations has the same slopes but different y-intercepts, then these two equations must be parallel with each other.

The dimensions of the decks increased by the 11 feet.

According to the statement

We have to find that the length by which we increase the dimensions.

So, For this purpose, we know that the

The Area is the amount of space occupied by a two-dimensional figure.

From the given information:

Ashley has a deck that measures 22 feet by 11 feet. She wants to increase each dimension by equal lengths so that its area is tripled.

Then

The shape of the deck is the rectangle then dimensions is 22 feet by 11 feet.

Then

Area of the deck with the given dimensions =  Length * Breadth

Area of the deck with the given dimensions =  22* 11

Area of the deck with the given dimensions =  242.

Then the dimensions increased by the x

Then

Area of the deck with the given dimensions =  Length * Breadth

Area of the deck with the given dimensions =  (22+x)* (11+x)

Area of the deck with the given dimensions =  242 + 22x+11x+x^2

Area of the deck with the given dimensions =  242 + 33x+x^2

Then according to given details:

x^2 + 33x + 242 = 3*242

x^2 + 33x + 242 = 726

x^2 + 33x = 726 - 242

x^2 + 33x = 484

x^2 + 33x - 484 = 0

After solving

The value of the x become

x = 11 and x = -44

Then second option be neglected.

Then the length increased by the 11 feet.

Natalie’s current available balance is $116.07.

To find current available balance, we need to subtract pending deposits/ credits with pending withdrawals/ debits.

Account Balance = Pending deposits / credits – Pending Withdrawals /debits

= $126.02- $97.68 = $28.34

Available Balance = Account Balance + Current Posted Balance

= $28.34 +$87.73 = $116.07

Current Available Balance = $116.07

The balance in checking or demand accounts that is available for use by the client or account holder is known as the available balance. The accessible balance of an account holder may not match the current balance. Any unfinished transactions are often included in the current balance.

Pending Deposit Credits: Pending check deposits that haven't been processed, haven't been credited to your account, or didn't have availability when we got them.

Pending Deposit Debits: Your account is put on hold for the transaction's amount until it is processed.

Hence Natalie’s current available balance is $116.07.

The sum of finite arithmetic series 1+4+7+ . . . . . .+31 is S(11) = 176

The given  arithmetic series is:

      1+4+7+ . . . . . .+31

From the above series, we know that:

The first term, a(1) = 1

The last term, a(n) = 31

The common difference, d = 4 - 1 = 3

Recall the formula to find the nth term of an arithmetic sequence:

a(n) = a(1) + (n-1) . d

Substitute a(1) = 1, a(n) = 31, and d = 3:

31 = 1 + (n-1) . 3

31 = 3n - 2

3n = 33

n = 11

In an arithmetic series, the sum of the first n terms is given by:

S(n) = n/2 [ a(1) + a(n) ]

Substitute n = 11, a(1) = 1, and a(n) = 31:

S(n) = 11/2 (1 + 31)
