Select the correct answer. A linear function has a y-intercept of -12 and a slope of 3/2. What is the equation of the line? y =
aniked [119]

Answer:

The equation of the line is:

  • y\:=\:\frac{3}{2}x\:-12

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given

  • y-intercept b = -12
  • slope m = 3/2

now substituting b = -12 and m = 3/2 in the slope-intercept form of line equation

y = mx+b

y\:=\:\frac{3}{2}x\:+\:\left(-12\right)

y\:=\:\frac{3}{2}x\:-12

Therefore, the equation of the line is:

  • y\:=\:\frac{3}{2}x\:-12

A 24 foot ladder is placed against a building at an angle of 75⁰. How far is the bottom of the ladder from the building?
yanalaym [24]
24ft is the hypotenuse, at an angle of 75<span>⁰, and we need to find the adjacent.

We use cos(), which is adjacent divided by hypotenuse.

Therefore, we can find the adjacent by doing:

25 * cos(75) = 6.47ft

Round the answer however you like.</span>

5 1/2 <br> -<br> 3 3/4<br> ______
eimsori [14]
So first you want to convert both to have the same denominator.

5 1/2 - 3 3/4

To:

5 2/4 - 3 3/4

Now, to make it easier for me, I would convert both to an improper fraction.

5 2/4 -> 22/4

3 3/4 -> 15/4

So now you can just do,

22/4 - 15/4,

which is just 7/4.

This in mixed number form is 1 3/4.
