Answer:

y=2x+6

Step-by-step explanation:

slope intercept formula → y=mx+b

\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\

so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0

plugin 2 for m (or the slope) and 6 for b (y-intercept)

your answer → y=2x+6

For questions 13 – 15, find x so that q || r. State the converse used.
Grace [21]

Answer:

13. x = 7 ; Converse : Alternate interior angles are equal .

14.  x=12; Converse used : Linear pair

15.  x = 23; Converse: Corresponding angles are equal

Step-by-step explanation:

13.

Refer the attached figure

Given: q || r

\angle CBE =\angle DEB (Alternate interior angles )

So,  15x+3=108

15x=108-3

15x=105

x=\frac{105}{15}

x=7

So, x = 7 ; Converse : Alternate interior angles are equal .

14.

Refer the attached figure

Given q||r

\angle PQT = \angle STQ (Alternate interior angles

So,\angle PQT = \angle STQ=11x-28

Now\angle UTQ + \angle STQ = 180^{\circ}(Linear pair)

So,7x-8+11x-28=180

18x-36= 180

18x=216

x=\frac{216}{18}

x=12

So, x=12; Converse used : Linear pair

15.

Refer the attached figure

Given q||r

\angle BDC+\angle CDE = 90+2x

\angle BDE=\angle PBC(corresponding angles)

90+2x=5x+21

90-21=5x-2x

69=3x

23=x

So, x = 23; Converse: Corresponding angles are equal

A building casts a shadow 48 feet long . At the same time a 40 foot tall flag pole casts a shadow 9.6 feet long . What is the fi
tankabanditka [31]
Ratio of height of the flag pole to the length of its shadow = 40:9.6 = 25:6
Ratio of height of the building to the length of its shadow = x:48 = 25:6
x/48 = 25/6
x = (48 x 25)/6 = 1200/6 = 200

Therefore, the height of the building is 200 feet.
