Answer:

In systems theory, a linear system is a mathematical model of a system based on the use of a linear operator. Linear systems typically exhibit features and properties that are much simpler than the nonlinear case.

If two lines in a linear system intersect they have exactly one point in common.

If two lines in a linear system are consistent they occupy the same space at the same time and have all their points in common.

If two lines in a linear system are parallel, they do not have any points in common.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 5 - 9 is an equation.

We have,

If two lines intersect they have exactly one solution.

If two lines are parallel they do not have any points in common.

If two lines are consistent the lines are in the same space at the same time and have all their points in common.

Thus,

Option 1 = intersect.

Option 2 = consistent.

Option 3 = parallel.

[tex]D.\ y = \frac{5}{2} - 4[/tex]

Step-by-step explanation:

Given

[tex]5x - 2y = 18[/tex]

Required

Determine parallel line

First, we need to convert the equation to slope intercept form

[tex]5x - 2y = 18[/tex]

[tex]- 2y = 18 - 5x[/tex]

Make y the subject:

[tex]y = \frac{18}{-2} - \frac{5x}{-2}[/tex]

[tex]y = -9 + \frac{5}{2}x[/tex]

[tex]y = \frac{5}{2}x - 9[/tex]

The general form of an equation is:

[tex]y=mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparison:

[tex]m = \frac{5}{2}[/tex]

From the condition of parallel equation.

A parallel equation will have an equal slope of [tex]\frac{5}{2}[/tex]

From the list of given options, option D has a slope of [tex]\frac{5}{2}[/tex]

Answer:

275 minutes 12 seconds

Step-by-step explanation:

Given that :

slowest running time per mile = 9 minutes and 14 seconds

fastest running time per mile = 7

minutes and 58 seconds.

To estimate the time taken to run 16 miles ;

Obtain the Average of the two run times :

(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second

Hence it takes an average of 17 minutes 12 seconds per mile

Time taken to run 16 miles :

((17 * 60) + 12) * 16 = 16512 seconds

16512 / 60 = 275 minutes 12 seconds

Answer:

"First, work out the difference (decrease) between the two numbers you are comparing. Decrease = Original Number - New Number. Next, divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100. If the answer is a negative number, this is a percentage increase."

Answer:

y= -14x +5

I hope this helps :)

Answer:

y = -14x + 5

Step-by-step explanation:

The slope of this line is -14. The y-intercept is 5. So, your equation (y = mx + b) is filled in with these numbers: y = -14x + 5.

25 miles per gallon

Step-by-step explanation:

Miles per gallon is the same as: [tex]\frac{miles}{gallon}[/tex]. The graph shows that when 2 gallons of gasoline are used, 50 miles are driven. So you would do [tex]\frac{50}{2}[/tex], which is 25.

Hope it helps!

The car gets 25 miles per gallon, as shown in the graph.

As mentioned in the question, the graph below shows the distance a car can travel, y, using gallons of gasoline.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
Since the graph shows the linear function passing through the origin,
For an instance,
Distance traveled = 200
Fuel consumed = 8 gallons
Rate = 200 / 8
Rate = 25 miles per gallon,

Thus, the car gets 25 miles per gallon, as shown in the graph.

Hello its 16

Step-by-step explanation:

Answer:

i think it is 12

Step-by-step explanation:

Answer:

1) because they are the two legs of the given isosceles triangle.

2) because the line AB is a perpendicular bisector of line BC.

3) because line AB intersects line DC in a perpendicularly and angle of a perpendicular line to a horizontal line is 90°.

4)because of the perpendicular bisector passing through angle A that divides the angle into 2 equal parts.

5)because it's the same line bisector.

6) because corresponding sides and angles of both triangles are equal.

Step-by-step explanation:

1) AD is approximately equal to AC because they are the two legs of the given isosceles triangle. And the two legs of an isosceles triangle are always equal.

2) AB is perpendicular to BC because of the line AB is a perpendicular bisector of line BC.

3) ∠ABD = ∠ABC are right angles because line AB intersects line DC in a perpendicularly and angle of a perpendicular line to a horizontal line is 90°.

4) ∠ABD = ∠ABC because of the perpendicular bisector passing through angle A that divides the angle into 2 equal parts.

5) AB = AB because it's the same line bisector.

6) Triangle ABC is equal to triangle ABD because corresponding sides and angles of both triangles are equal.
