One decimal place means one place after the decimal point, therefore you should round appropriately to get to one place after the decimal point.

What is the equation of a line that is parallel to -x+3y=6 and passes through the point (3,5)?
Elena-2011 [213]

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

A guy-wire is attached to a pole for support. If the angle of elevation to the pole is 67° and the wire is attached to the groun
vovangra [49]
You have to go at this in a round-about fashion...by finding the length of the leg across from the 67 degree angle.  This is found by using the tangent ratio...Tan(67)=x/137; x=137tan(67) = 322.8. Now you can use this in one of two ways: use Pythagorean's Theorem to find the length of the hypotenuse OR you could use the sin67=322.8/x.  Up to you. Either way, make sure you have your calculator in degree mode!
