Answers:

Answer for row one:     1

Answer for row two:     11

Answer for row three:   16

Answer for row four:     36

=========================================

Work Shown:

Whatever the x value is, we multiply by 5 and subtract off 14 to get the corresponding y value. This is following the order of operations PEMDAS

------------

If x = 3, then

y = 5*x - 14

y = 5*3 - 14  ..... note how x is replaced with 3

y = 15 - 14

y = 1

This means that when x = 3, the y value is y = 1.

So 1 goes in the box in the first row.

---------------

Repeat for x = 5

y = 5*x - 14

y = 5*5 - 14

y = 25 - 14

y = 11

We have 11 as the second answer.

--------------

Repeat for x = 6

y = 5*x - 14

y = 5*6 - 14

y = 30 - 14

y = 16

The third answer is 16.

--------------

Repeat for x = 10

y = 5*x - 14

y = 5*10 - 14

y = 50 - 14

y = 36

The last answer is 36.

A ladder 15 feet long leans against a wall and forms an angle of 45º with the ground. How far from the wall is the ladder?
bezimeni [28]
The ladder is the hypotenuse of a 45 45 90 triangle.
The legs of a 45 45 90 triangle = hypotenuse / sqroot (2)

15 / 1.414 = 10.608

(Incidentally it is the "bottom" of the ladder that is 10.608 feet from the wall.  The "top" of the ladder is touching the wall.  LOL)
