[tex]y = 3x - 2 \\ y - 2 = x[/tex]
that's the problem ​

Answers

Answer:

The solution to the system of equations be:

x = 2, y = 4

Step-by-step explanation:

Given the system of equation

y - 2 = x

y = 3x - 2

substitute y = 3x - 2 in the equation y - 2 = x

y - 2 = x

(3x - 2) - 2 = x

3x -2 -2 = x

3x - 4 = x

add 4 from both sides

3x - 4 + 4 = x + 4

3x = x + 4

subtract x from both sides

3x - x = x + 4 - x

3x - x = 4

2x = 4

divide both sides by 2

2x/2 = 4/2

x = 2

For y = 3x - 2, plug in x = 2

y = 3x - 2

y = 3(2) - 2

y = 6 - 2

y = 4

Therefore, the solution to the system of equations be:

x = 2, y = 4

Your answer is 90

You can see that there’s a right angle on the right side of the triangle.
Or, if you want to be more specific:

Since two triangles are congruent,
Angle w=62

So, 180-(28+62)

After solving the equation, the value obtained for x is equal to 1.

What is an equation?

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given equation in the question,

13x - 12 = 7x - 6

13x - 7x = -6 + 12

6x = 6

x = 6/6

x = 1

Therefore, the value obtained for x will be equal to 1.

Answer:

[tex]a_{n}[/tex] = 10n - 5

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 15 - 5 = 25 - 15 = 10

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 10 , then

[tex]a_{n}[/tex] = 5 + 10(n - 1) = 5 + 10n - 10 = 10n - 5

The true statements of the angles of the parallel lines are

a) m∠1 = m∠8

b) m∠6 = m∠7

c) m∠4 + m∠6 = 180°

d) 180° - m∠7 = m∠9 + m∠10

What are Parallel Lines Cut by Transversal?

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

The true statements are

a) m∠1 = m∠8 ( alternate exterior angles )

b) m∠6 = m∠7 ( vertically opposite angles )

c) m∠4 + m∠6 = 180° ( co-interior angles are supplementary )

d) 180° - m∠7 = m∠9 + m∠10 ( triangle exterior angle theorem )

Hence , the angles of the parallel lines are solved
