The perimeter of a rectangle is:
2L +2W = P
W = x
L = 3x - 75

2(x) + 2(3x - 75) = 810

2x + 6x - 150 = 810
8x = 960
x = 120; W = 120 ft. L = 285 ft

P = 2l +2w
820 = 2(w - 70) + 2w
<span>820 = 4w - 140  </span>
<span>820 - 140 = 4w</span>
<span>680/4 = w
170 = w
let me know if you need an explanation of how i got any of the steps

What is the vertex of the parabola with the equation y=1/5x^2 + 2x - 8
bixtya [17]

Answer:

(-5,-13)

Step-by-step explanation:

Find the vertex of the parabola y=1/5x^2+2x−8.  

In this equation a=15  and b = 2.  

x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5

Substitute −5 into the equation y=1/5x^2+2x−8

y=1/5(−5)^2+2(−5)−8

y=5−10−8

y=−13

The vertex is (−5 , −13)

Let ax-by=c, where a,b,c&gt;0. Rewrite the equation in slope-intercept form
Elis [28]

Here we are required to rewrite the equation ax-by=c, where a,b,c>0 In the slope-intercept form.

The slope-intercept form of ax-by=c is ;

y = (a/b)x - (c/b).

There a no. of ways to write the equation of a line; however, the most popular of these ways is the slope-intercept form.

  • The slope-intercept form usually takes the form ; y = mx + c.

Therefore, the equation ax-by=c can be rewritten thus;

  • ax - c = by
  • By divIDing both sides of the equation by b, we have ;
  • (a/b)x - (c/b) = y

Consequently, the slope-intercept form of ax-by=c is ;

  • y = (a/b)x - (c/b).
  • where , (a/b) is the slope(m)
  • and (-c/b) is the intercept(c).

What is the percentage increase of a room that is the size of 96 square feet to a room that is 108 square feet?
katrin [286]

Answer:

12.5% increase OR 112.5% Percentage of Change

Step-by-step explanation:

For this problem consider that our original maximum value is 96 square feet, but our new maximum value is 108 square feet. So to find the change as a percentage (in this case the increase) use the following formula:

Percentage of Change = ( New Maximum / Old Maximum ) * 100

So, let's use this formula to find the percentage change of the room.

Percentage of Change = ( 108 / 96 ) * 100

Percentage of Change = (1.125) * 100

Percentage of Change = 112.5

So the percentage of Change is 112.5%. Note, the old maximum is the point of comparison which is 100%.

So to find the increase, we will do 112.5% - 100% to get 12.5%. Hence, we have a 12.5% increase of a 108 square foot room compared to a room of 96 square feet.

Cheers.
