Answer:A coordinate system is a two-dimensional number line

Step-by-step explanation:

A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes. An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x,y

The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

There are an ordered pair and coordinates.

Now,

The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

And, An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of

(a, b) and a coordinate system is a two-dimensional number line.

Thus, The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

Answer:

  -49

Step-by-step explanation:

In order to fill in the given expression, we need to know ...

Then the expression is ...

  √(5 -(-4)) -(-7)² +7÷(-7)·(3) = √9 -49 +7/(-7)(3)

  = 3 -49 +(-1)(3) = 3 -49 -3

Answer:

Basically, you need to plug 5 in as y

Step-by-step explanation:

First, plug 5 in the place of Y 10 * 5 + 6

Then solve the equation from there.

10 * 5 = 50

50 + 6 = 56

The degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that:

The measuring unit is the degree

The measurement can be defined as the numerical quantity that gives an idea about object length, width, and many more. It can be used to compare two objects.

As we know from the definition of the angle; two lines or rays converge at the same point, and the measurement between them is called an "Angle."

The degree measures an angle which is the measure of incline.

Thus, the degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

Answer

18

Step-by-step explanation:

m+7−5=20

Step 1: Simplify both sides of the equation.

m+7−5=20

m+7+−5=20

(m)+(7+−5)=20(Combine Like Terms)

m+2=20

m+2=20

Step 2: Subtract 2 from both sides.

m+2−2=20−2

m=18

Step-by-step explanation:

The first step is to line it up in the Pythagorean theorem, then you want to move the [tex]6^{2}[/tex] to the other side of the equation via subtraction from both sides in order to isolate the [tex]x^2[/tex]. After that, you'll end up with [tex]x^{2} =64[/tex] then you'll want to square root both sides and end with [tex]x=8[/tex].

Answer:

Intersecting

Step-by-step explanation:

Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.

Step-by-step explanation:

A=½bh

A=½(4•3)

A=½(12)

A=6 units sq

The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

First, you must flip the equation

[tex]12k+29[/tex] ≥ [tex]120[/tex]

Then, you must subtract 29 on both sides

[tex]12k[/tex] ≥ [tex]91[/tex]

Finally, divide both sides by 12

[tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]
