Answer:

x = - 5

Step-by-step explanation:

5x + 23 = - 2x - 12 ( add 2x to both sides )

7x + 23 = - 12 ( subtract 23 from both sides )

7x = - 35 ( divide both sides by 7 )

x = - 5

Answer: 5

Solution,

5x+23=-2x-12
or, 5x+23+2x=-12
or, 5x+2x=-12-23
or, 7x=35
or, x=35/7
Therefore, x=5

Suppose that for a certain company C(x)=35x+300,000 represents the total cost function, and R(x)=75x represents the total rev

enyata [817]

Answer:

40x - 300,000

7,500

Step-by-step explanation:

profit = revenue - cost

p(x) = 75x - (35x + 300,000)

p(x) = 40x - 300,000

Break even is when profit is zero

40x - 300,000 = 0

40x = 300,000

x = 7,500

Answer:

1/8

Step-by-step explanation:

The slope equation for this problem is

y2-y1

--------

x2-x1

So the y2=4, y1=3, x2=8, and x1=0

4-3 =1

----- --

Answer:

Last option: 4

Step-by-step explanation:

The quadratic equation simplified: $x^2-4x=-\frac{7}{2}$ has the form:

$ax^2+bx=c$

In this case, you can identify that "a", "b" and "c" are:

$a=1\\b=-4\\c=-\frac{7}{2}$

To solve this quadratic equation by completing the square, Carlos should add $(\frac{b}{2})^2$ to both sides of the equation. This is:

$(\frac{-4}{2})^2=(-2)^2=4$

Then:

$x^2-4x+4=-\frac{7}{2}+4$

Therefore you can observe that the number he should add to both sides of the equation is: 4
