Write equations for the horizontal and vertical lines passing through the point (-2,-5).
erastova [34]

Answer:

  • y = -5
  • x = - 2

=============================

The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:

  • y = - 5

The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:

  • x = - 2

SHOW THE SOLVING FOR <br> 4v+18&gt;_ 6v+10
SOVA2 [1]
Remember you can do anything to an equaiton as long asyou do it to both sides

4v+18≥6v+10
minus 4v both sides
4v-4v+18≥6v-4v+10
0+18≥2v+10
18≥2v+10
minus 10 both sides
18-10≥2v+10-10
8≥2v+0
8≥2v
divide both sides by 2
8/2=(2v)/2
4≥(2/2)v
4≥1v
4≥v
v≤4

Each side of the equilateral triangle shown is 3 inches long. What is the height of the triangle?
rodikova [14]

•  measure of the side:   s = 3 in


You can find the height  h  by this formula:

          s · √3
h  =  ————
              2

          3 · √3
h  =  ————
              2

           3√3
h  =  ————  in     (exact value)
             2


Using  √3 ≈ 1.73,

           3 · 1.73
h  ≈  —————
                2

           5.19
h  ≈  ————
             2

h ≈ 2.60 in   (approximate value)


I hope this helps. =)
