If m<W=9x-3 and m<Z=3x+15 solve for x​

Mathematics

Answer:

x = 14

Step-by-step explanation:

W and Z are adjacent angles. So they are supplementary and add to 180 degrees.  

W + Z = 180  

9x - 3 + 3x + 15 = 180  

12x + 12 = 180 12x = 180 - 12  

12x = 168  

x = 168/12

The given graphs show functions which have been transformed from the quadratic parent, f(x) = x2. Determine which transformation
Artyom0805 [142]

Answer:

The tansformations of were applied to the quadratic parent function to result in each graph are g(x), h(x) and d(x) with translation

Further explanation

Transformations definition is it involved by taking a preimage and transforming it in some way to produce an image.

Mathematical transformations have four main types: translation, rotation, reflection and dilation

Rotation is done by rotating an object about a fixed point without changing its size or shape

Translation is done by moving an object in space without changing its size, shape or orientation

Dilation is done by expanding or contracting an object without changing its shape or orientation

Reflection is done by flipping an object across a line without changing its size or shape

The given graphs show functions which have been transformed from the quadratic parent, f(x) = x^2f(x)=x

2

Which transformations were applied to the quadratic parent function to result in each graph?

Quadratic parent: f(x)=x^2f(x)=x

2

The graph is a parabola with V=(0,0)V=(0,0) at the origin

If x=1x=1 then f(1)=1^2 = 1f(1)=1

2

=1

Vertical shift means shifting in y axis. Whereas horizontal shift means shifting in x axis. Shift down means go to lower value of axis, whereas shift left goes to higher value of axis

For g(x)g(x) : vertical shift down 3 and horizontal shift left 3

For h(x)h(x) : reflection across the x-axis and vertical strecht of 3

Suppose △ABC has exterior angle at vertex B. The exterior angle is (12x−24)°, m∠A=(3x−6)°, and m∠C=(6x+12)°. What is the measure
Temka [501]

Answer: 96°

Step-by-step explanation:

If a triangle is being drawn, Angle A and C will be the two remote interior angles in the triangle. The sum of the two interior angles has to equal to the exterior angle.

Set them equal each other and solve for x.

(3x-6) + (6x +12) = 12x - 24     Combine like terms

9x + 6 = 12x - 24          Subtract 6 from both sides

    - 6             -6  

   9x = 12x - 30             Subtract 12x from both sides

-12x       -12x  

    -3x = -30               Divide both sides by -3    

 x = 10      

Now since  x is 10 degrees we will need to input the value into in for x in the exterior angle expression and break it down.  

   Exterior :  12(10) - 24

                    120 - 24  = 96

    This means the measure of the exterior angle at vertex B is  96 degrees.
