Plz help I don’t understand how to find x?

Mathematics

Oliga [24]3 years ago

Answer:

x = -4

Step-by-step explanation:

First lets add 82 + 55 which equals 137, then 137 +47 which equals 184

Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.

-x + 184 = 180

-x = -4

Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.

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
