These 2 equations has no solution and the equations are independent of each other.

<u>Step-by-step explanation:</u>

-10x² -10y² = -300 ----a

5x² + 5y² = 150 ---- b

While trying to solve this,

We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.

10x² + 10y² = 300 ----c

-10x² -10y² = -300 ---a

Everything cutoff, we will get 0, and there is no solution to these equations.

Rearrange the equation so xxx is the independent variable. Pls Help :)<br><br>−5x−4y=−8
S_A_V [24]

The rearranged expression will be equal to y = (-5/4)x + 2.

<h3>What is an expression?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

<h3 />

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be rearranged as below:-

−5x−4y=−8

Solve the above expression for the value of y and the x variable will become independent.

−5x−4y=−8

Take -5x to the right side of the equation.

-4y = 5x - 8

Divide the equation by -4.

y = ( -5 / 4 )x + 2

Therefore, the rearranged expression will be equal to y = (-5/4)x + 2.

How do you find the value of x while working with adjacent and vertical angles? The angle is adjacent btw if that helps... I am
katrin [286]

Answer:

The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.

x = 28

Step-by-step explanation:

When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.

(x + 6) + 56 = 90

x + 62 = 90

x = 28
