-1/2 = 3/8y solve for y

valentinak56 [21]

Answer:

y = -4/3

Step-by-step explanation:

cross multiply

-1(8) / 2(3)

=-8/6

simplify -8/6

y = -4/3

now substitute

-1/2=3/8(-4/3)

-1/2=-12/24

-1/2=-1/2

y= -4/3

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x

marusya05 [52]

we have

$x^{2} + 27x + 162$

Using a graph tool------> to resolve the second order equation

the solution is

$x=-18\\ x=-9$

so

$x^{2} + 27x + 162=(x+18)*(x+9)$

therefore

the answer is the option

length = (x + 18) inches and width = (x + 9) inches

Jimmy owns a small engine repair business. The revenue, in dollars, can be modeled by the equation y = 420 + 72x, where x is the

kozerog [31]

Answer:

5 hours

Step-by-step explanation:

Given

$y = 420 + 72x$ --- Revenue

$y = 24x^2 + 180$ --- Overhead cost

Required

Determine the hours for break even

To do this, we simply equate both expressions as follows:

$24x^2 + 180 = 420 + 72x$

Collect Like Terms

$24x^2 - 72x + 180 - 420 = 0$

$24x^2 - 72x -240 = 0$

Divide through 24

$x^2 - 3x - 10 = 0$

Expand:

$x^2 -5x + 2x -10 = 0$

Factorize:

$x(x -5) + 2(x -5) = 0$

$(x + 2)(x -5) = 0$

$x + 2 = 0\ or\ x - 5 = 0$

$x = -2\ or\ x = 5$

But x can't be negative because it represents time.

<em>So, x = 5 hours</em>
