SA = ? 
<span>r = 2x - 1 </span>
<span>h = 3x </span>

<span>Then, </span>

<span>SA = 2π(2x - 1)² + 2π(2x - 1)(3x) </span>
<span>==> 2π(4x² - 4x + 1) + 6πx(2x - 1) </span>
<span>==> 8πx² - 8πx + 2π + 12πx² - 6πx </span>
<span>==> 20πx² - 14πx + 2π units² </span>

Y-1/4x=-1 <br> y-2=4x <br> one solution, no solution or infinite solution?
alexandr1967 [171]

Answer:

One solution

Step-by-step explanation:

To start, let's simplify the equations to slope-intercept form

y - 1/4x = =1

  +1/4x     +1/4x

y           = 1/4x - 1

y - 2 = 4x

  +2          +2

y       = 4x + 2

As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.

15/3 = 5
so
(3x+ 8)/5 = 4
3x + 8 = 20
3x = 12
  x = 12/3
  x = 4

answer is x = 4
