3x+6=-3(2x+4) Show your work

Lera25 [3.4K]

Answer:

$\boxed {x = -2}$

Step-by-step explanation:

Solve for the value of $x$ :

$3x + 6 = -3(2x + 4)$

-Use Distributive Property:

$3x + 6 = -3(2x + 4)$

$3x + 6 = -6x - 12$

-Take $6x$ and add it to $3x$ :

$3x + 6 + 6x = -6x + 6x - 12$

$9x + 6 = -12$

-Subtract both sides by $6$ :

$9x + 6 - 6 = -12 - 6$

$9x = -18$

-Divide both sides by $9$ :

$\frac{9x}{9} = \frac{-18}{9}$

$\boxed {x = -2}$

Therefore, the value of $x$ is $-2$ .

A bookstore costs $90 a day to keep open, and spends $12 for each book it sells. the store charges $18 for each book it sells. I

denpristay [2]

Total Cost in a day is $TC= 90 + 12n$ . Profit function is $P=18n$ . And the revenue function is $R = P-TC = 18n-12n-90 = 6n-90$ . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.

X^2+y^2=25 find the distance of point (x,y) from origin

storchak [24]

Answer:

Step-by-step explanation:

The radius is 5.

All I do was think of the center-radius form a circle

(x-h)^2+(y-k)^2=r^2

x^2 + y^2 =25

(x-0)^2+(y-0)^2=5^2

The center is (0,0) and the radius is 5.

So a point on the circle (x,y) has a distance of 5 from the center

and the center's case here is (0,0).
