Answer:

x = 12

Step-by-step explanation:

The exterior angles of any polygon always add up to 360, so:

$5x+4+4x+9+7x+4+9x-6+4x+1=360\\29x+12=360\\29x = 348\\x = 12$

You paint 13 of a wall in 14 hour. At that rate, how long will it take you to paint one wall?

umka21 [38]

I assume you mean 1/13 of a wall.

This means in 14 hours you paint one piece of a wall that is divided equally into 13 sections. If we paint all 13 of those sections, we get that 13 * 14 = 13 * 10 + 4*13 = 130 + 52 = 182 hours.

Which equation is the inverse of 5y+4 = (x+3)^2 + 1/2?

katovenus [111]

we have

$5y+4=(x+3)^{2}+\frac{1}{2}$

Step 1

Swap x and y

$5x+4=(y+3)^{2}+\frac{1}{2}$

Step 2

Solve for y

$5x+4-\frac{1}{2}=(y+3)^{2}$

$(y+3)^{2}=5x+\frac{7}{2}$

Square root both sides

$(y+3)=(+/-)\sqrt{5x+\frac{7}{2}}$

$y=(+/-)\sqrt{5x+\frac{7}{2}}-3$

Step 3

Let

$f(x)^{-1}=y$

$f(x)^{-1}=(+/-)\sqrt{5x+\frac{7}{2}}-3$

therefore

<u>the answer is the option D</u>

$y=-3(+/-)\sqrt{5x+\frac{7}{2}}$
