The top one shows they are parallel lines because it shows angles of both lines and the transversal

Answer: The answer is the first diagram.

Step-by-step explanation:  We are given two diagrams out of which we are to select the one which shows lines must be parallel lines cut by a transversal.

In the first figure, the sum of two interior angles is given by

115^\circ+65^\circ=180^\circ,

which shoes that the two lines which cut by a transversal are parallel. So, this option is correct.

In the second figure, the sum of two angles on a straight line is given by

115^\circ+65^\circ=180^\circ,

which shows that a straight angle is of measure 180°, which does not have any relation in proving the two lines to be parallel. So, this diagram is not correct.

Thus, the first diagram is the correct option.

PLEASE HELP ME!!!!!!!!!
Makovka662 [10]

Answer:

  (a)  (5, -3)

Step-by-step explanation:

The "substitution method" for solving a system of equations requires that you write an expression that can be substituted for a variable in one or more of the other equations in the system.

<h3>Expression to substitute</h3>

The given equations are ...

  • y = x -8
  • 2x +3y = 1

We notice the first equation gives an expression for y. This is exactly what we want to substitute for y in the second equation.

<h3>Substitution</h3>

When the expression (x-8) is substituted for y in the second equation, you get ...

  2x +3(x -8) = 1

This simplifies to ...

  5x -24 = 1

<h3>Solution</h3>

This 2-step equation can now be solved in the usual way:

  5x = 25 . . . . . . add 24 to isolate the variable term

  x = 25/5 = 5 . . . . . divide by the coefficient of x

Note that we now know what the correct answer choice is.

Using the expression for y, we find ...

  y = x -8 = 5 -8 = -3

The solution is (x, y) = (5, -3).

__

The attached graph confirms this solution.

Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly. Write a compound inequality
Evgesh-ka [11]

Answer:

<em>The compound inequality that shows the voltage amount the necessary range is  3.5</em>

Step-by-step explanation:

Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly.

That means, <u>the voltage amount should be either greater than 3.5 volts or less than 7.2 volts</u>.

Suppose, the amount of voltage is V volts to make the experiment work correctly.

Now, Voltage amount is greater than 3.5 volts means:  V>3.5 or 3.5

and voltage amount is less than 7.2 volts means:  V

Thus, the compound inequality by combining the above two inequalities will be:   3.5
