Graph the linear equation. Find three points that solve the equation, then plot on the graph. -3y=x-6
nata0808 [166]

Answer:

Step-by-step explanation:                               x - 6

The given equation can be re-written as y = ---------                              

                                                                             -3

Arbitrarily choose x = 0.  Then:

      x - 6         0-6

y = --------- = ----------- = 2, so (0, 2) is a point on the graph which is also the                              

          -3            -3                                                                  y-intercept

Arbitrarily choose x = 6.  Then y = 0, and (6, 0) is another point on the graph                                    

                                                              which happens to be the x-intercept

arbitrarily choose x = 12.  Then y = (12 - 6) / (-3) = -2.  Then  (12, -2) is            

                                                                                  another point on the

                                                                                  graph.

Plot (12, -2), (6, 0) and (0, 2).  Draw a line through these three points.

Answer:

  • 150.72 cm³
  • 314 cm³
  • 160 cm³
  • 48 cm³

Step-by-step explanation:

Put the given numbers in the relevant formula and do the arithmetic.

<u>right cylinder</u>

   V = πr²h = 3.14(4 cm)²(3 cm) = 3.14×48 cm³ = 150.72 cm³

<u>cone</u>

  V = 1/3πr²h = 1/3(3.14)(5 cm)²(12 cm) = 3.14×100 cm³ = 314 cm³

<u>pyramid of unknown shape</u>

  V = 1/3Bh = 1/3(16 cm²)(30 cm) = 160 cm³

<u>square pyramid</u>

  V = 1/3s²h = 1/3(3 cm)²(16 cm) = 48 cm³
