Are the graphs of the lines in the pair parallel? Explain. y = 4x – 4 24x – 4y = 96

Radda [10]

Answer:

They are not parallel.

Put the equation in y=mx=b format to compare. The first equation (y=4x-4) is already in the right format.

If m (slope) is the same, then the lines are parallel.

-4y=96-24x

/-4 all sides

y= - 24+ 6x

y=6x-24

y=4x-4

6 is not equal to 4, slopes are not the same. Not parallel.

1. Check the sketch of the problem.

2. In right triangle DCE,

$tan50= \frac{EC}{DC}= \frac{x}{50}$

tan 50 can be found to be 1.19 using a scientific calculator or other software.

$1.19=\frac{x}{50}$

x=1.19*50=59.5 (feet)

3. The height of the building is 59.5+5=64.5 (feet)
