Find the equation of the line that passes thru (-1,-5) and is parallel to 3x+y=-5. Show work.

sertanlavr [38]

Answer:

$y=-3x-8$

Step-by-step explanation:

slope-intercept form:

$y=mx+b$

Start with the given equation, and to find the slope, convert it to slope-intercept form by solving for y.

$3x+y=-5$

In this case, all you need to do is subtract 3x from both sides.

$y=-3x-5$

Here, the slope is -3. The slope of a parallel line will also be -3.

Now, we have 3 known variables. We have the slope and the x and y of a known point. Use those 3 knowns to solve for the 1 unknown, the y-intercept.

$y=mx+b\\-5=(-3)(-1)+b\\-5=3+b\\-8=b\\b=-8$

Finally, with the slope and the y-intercept, you can write the equation of the line:

$y=-3x-8$

21 feet to 8 yards write a ratio as a fraction in simplest form without any units

Dmitriy789 [7]

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = $\frac{21 feet}{3 feet}yards$ = 7 yards

Thus, the ratio

$\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}$

The fraction $\frac{7}{8}$ is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is $\frac{7}{8}$

The complement of an angle measures 20 more than the angle. Find the number of degrees in the angle

padilas [110]

Let the measure of its complement be x°.
