The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x +

12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?

Answer:

$472 in a month

Step-by-step explanation:

The total charge that an instructor takes for giving lessons is given by  

y = 8x + 12 ........ (1), where x in hours is the number of hours he gives lessons and y in the dollar is the total charge for his lessons.

Now, the instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela.

Therefore, the instructor makes an amount of [( 8 × 32 + 12 ) + ( 8 × 24 + 12 )] = $472 in a month. {From equation (1)}

I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.

Answer:

  • Dilation
  • Reflection
  • Translation
  • Rotation
  • Reflection
  • Translation

Step-by-step explanation:

<em>Dilation</em>

Dilation multiplies the distance from a point to the center of dilation by the dilation factor. It does this for every point.

The center of dilation itself has zero distance from the center of dilation. Multiplying that by the dilation factor still gives zero, so the point that is the center of dilation remains unchanged.

<em>Reflection</em>

Reflection mirrors a point across some line. Each point ends up the same distance on the other side of the line that it was originally from the line.

The segment joining a point with its reflection is perpendicular to the line, so the line of reflection is the perpendicular bisector of the segment joining any point with its image.

<em>Rotation</em>

The angle defined by a point, the center of rotation, and the point's image is the angle of rotation. It is the same for every point.

The center of rotation doesn't go anywhere; it is "invariant".

<em>Translation</em>

Moving an image without changing its size or orientation is translation. Every point moves the same distance in the same direction, so any lines in the original figure have the same length and orientation in the translated figure: they are parallel.

The line is parallel to y axis

We know that if a line is parallel to y axis

  • slope=tan90=undefined

So there is no slope

Here it has constant x value as -2

So the equation is

  • x=-2
