Hello!

<span>The constant of variation is xy. XY=23. If X=7 then Y=23/7.
</span>
So as we can see, the stated inverse variation can be represented as the equation y = k/x. ===> k = 23 & x = 7 ⇒ y = 23/7. <====

HELP ME PLEASE !!!!

For this one, an easy way to solve it is to break it down into parts.  First lets convert 5 feet to inches.  

Multiply the number of feet by how many inches are in one foot.  

5 times 12= 60 in

Now just add the like terms

60 in + 2 in= 62 inches.

Now we see that Sarah is 62 inches tall, now we can convert to centimeters the same way.

62 times 2.54= 157.48

So that makes C your answer, Sarah is 157.48 cm tall.

Solve for x in the following:<br> 8x^2 + 6x = -5
artcher [175]

Answer:

No solution or

(-3±2i\sqrt{31})/8

Step-by-step explanation:

To get the solution, move everything to the left side of the equation:

8x²+6x+5 = 0

If you try to factor the equation or graph it, you will see that it will never equal 0.

If you need an imaginary solution you can plug it into the quadratic equation:

-6±\sqrt{36-160} over 16

Simplify and you get

-6±i\sqrt{124} over 16

-6±4i\sqrt{31} over 16

Simplify the fraction and you can get

(-3±2i\sqrt{31})/8
