What is the equation of a line that is parallel to -x+3y=6 and passes through the point (3,5)?

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

We have the following line:

-x + 3y = 6\\3y = x + 6\\y = \frac {1} {3} x + \frac {6} {3}\\y = \frac {1} {3} x + 2

Thus, the slope is:m_ {1} = \frac {1} {3}

Then m_ {2} = \frac {1} {3}

So, the line is of the form:

y = \frac {1} {3} x + b

We substitute the point(x, y) :( 3,5)and find b:

5 = \frac {1} {3} (3) + b\\5 = b

Thus, the equation is:

y = \frac {1} {3} x + 5

Answer:

y = \frac {1} {3} x + 5

andrew-mc [135]

Answer:

C

Step-by-step explanation:

1. Conan needs 4 hours to rehearse and host a good show.  Andy needs 10 hours to do the same. So, Cohan needs 6 hours less than Andy to  rehearse and host a good show. This means Cohan has an absolute advantage in the production of show hosting.

2. Conan writes one usable joke in an hour,  Andy needs 2 hours to do the same. So, Cohan has an absolute advantage in the production of joke writing.

Thus, Cohan has an absolute advantage in the production of both show hosting and joke writing.

Correct option is option C.

Find the area of an equilateral triangle with a side of 6 inches.
sweet-ann [11.9K]

Answer:

9\sqrt{3} in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = \frac{s^2\sqrt{3} }{4} ( s is the length of a side )

Here s = 6, thus

A = \frac{6^2\sqrt{3} }{4} = \frac{36\sqrt{3} }{4} = 9\sqrt{3} in²
