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>

Helpppppp me pleaseeeee<br> Divide the following integers. -12 � 4= -3 -8 -48 3
Orlov [11]

Answer:

Step-by-step explanation:

Simplify  -12\ 4−12÷4  to  -3−3.

-3=-3-8-48,3

−3=−3−8−48,3

2 Simplify  -3-8−3−8  to  -11−11.

-3=-11-48,3

−3=−11−48,3

3 Simplify  -11-48−11−48  to  -59−59.

-3=-59,3

−3=−59,3

4 Since -3=-59,3−3=−59,3 is false, there is no solution.
