If he works 14 hours then he will earn the amount of $105 which is true and if he works 16 hours then he will earn $120 which is true.

You should be aware that a linear equation is defined as an equation in which the highest power of the variable is one.

The given graph represents Elisa's work and the amount of money he earns at his job.

According to the given graph,

We can see two points are (4, 30) and (8, 60)

The linear equation will be

⇒ y - 30 = (60-30)/(8-4)(x-4)

⇒ y - 30 = (30)/(4)(x-4)

⇒ y - 30 = 7.5(x-4)

⇒ y = 7.5x - 30 + 30

⇒ y = 7.5x

Elisa's work = 14 hours then we verify the response by substituting x = 14 in the above equation,

⇒ y = 7.5(14)

⇒ y = 105

Thus,  if he works 14 hours then he will earn $105

Elisa's work = 16 hours then we verify the response by substituting x = 16 in the above equation,

⇒ y = 7.5(16)

⇒ y = 120

Thus, if he works 16 hours then he will earn $120.

Answer: (5, -2)

Step-by-step explanation:

They give you two equations with two variables. You can solve this using elimination or substitution. However, it seems as though the problem wants you to do it through elimination. On the right, you have the equation

    6x + 10y = 10

+  -6x - 24y = 18

After add these equations, you get -14y = 28. By dividing both sides by -14, you get y = -2. You can plug y = -2 back into either one of the original equations, and solve for x.

x = 5.

So your answer is (5, -2)

There are three types of coordinate systems in Revit: Project Coordinates, Shared Coordinates, and Site Coordinates.

There are three types of coordinate systems in Revit: Project Coordinates, Shared Coordinates, and Site Coordinates. Project Coordinates are the default coordinates used in Revit and are based on the project origin. This is the origin point of the model and all elements in the project are positioned relative to this point.

Shared Coordinates are used to link multiple projects together. This origin point is determined by a shared coordinate system, which is based on the origin of the shared coordinate system.

Site Coordinates are used to set the project origin in the real-world location of a site. This location is determined by the user and the coordinate values can be set in the Site Location dialog box. All elements in the project are then positioned relative to this real-world site location.

Step-by-step explanation:

You want to know the angle opposite the side of length 22 in a triangle in which a 28° angle is opposite a side of length 11.

The law of sines tells you ...

  sin(B)/b = sin(A)/a

  sin(x)/22 = sin(28°)/11

  sin(x) = 22/11 · sin(28°)

  x = arcsin(2·sin(28°)) ≈ 69.9° or 110.1°

There are generally two solutions to a Law of Sines problem in which the given angle is opposite the shorter of two given sides. The exception is when the triangle is a right triangle.

The sides 10 cm, 24 cm and 26 cm can form a right-angled triangle. The Pythagorean theorem can be used to verify this.

From Pythagorean theorem, it can be said that, the square of hypotenuse side is equal to the sum of other two sides of a right angled triangle.

Let AB, CA and BC be the sides of a right triangle. CA is the hypotenuse side, AB and BC are the base and height sides of the right triangle. The equation can then be expressed as,

CA² = AB² + BC²

Now, let us check this rule for the above given sides of the triangle.

Longest side² = Sum of squares of other two sides

26² = 24² + 10²

676 = 576 + 100

Thus, the sides 10 cm, 24 cm and 26 cm can form a right-angled triangle.

Answer:

b) m = -2 and b=10 and c) m= 2/5 and b=4

Step-by-step explanation:

For b, we know that the b value (y-intercept) is 10 because it is the y value when x= 0, which is shown on the table as 10.

Next, to find the slope (m-value) we know that 10 gets added to the y value so then x(2) + 10 = 6

subtract 10 from both sides and you get 2x = -4

divide both sides by 2 to get x= -2 or our m-value (slope)
-------------------------------------------------------------------------------------------------------------
For c, we know that the graph intercepts the y-axis at 4, so that is our b value.

We know know: y= m(x) + 4

To find the slope, we use the formula: rise/run

When the graph goes up 6 to get to y=10, the x value goes 15 across

Rise = 6 ;  Run = 15

6/15 = 2/5

Therefore, the m value is 2/5

Therefore , the solution of the given problem of triangle comes out to be CA = 8.94 cm .

An triangle is a polygon since it has four or more parts. It is a simple geometric shape. A square having angles A, B, and C is referred to as a triangle ABC. When the sides are not collinear, Euclidean geometry generates a single plane and square. If a triangle has three sides and three corners, it is a polygon. The corners of a triangle are where its three sides meet. The sum of the angles in a triangle is 180 degrees.

Here,

Given : A right triangle ,

Area  =16 cm squarea

=> 1/2 * b * h = 16

=> 8*h = 32

= > h  =4

Lines of longitude run north to south and measure places expressed in degrees east or west of the Prime Meridian.The basic work of the longitude lines is to show the distance at which a place lies, east or west of the Prime Meridian.

Longitude is a measurement of location east or west of the prime meridian at Greenwich, London, England, the specially designated imaginary north-south line that passes through both geographic poles and Greenwich. Longitude is measured 180° both east and west of the prime meridian.
