Answer:

x = -5

Step-by-step explanation:

3x + 2(x - 9) = 8x + x + 2

~Distribute left side

3x + 2x - 18 = 8x + x + 2

~Combine like terms

5x - 18 = 9x + 2

~Add 18 to both sides

5x = 9x + 20

~Subtract 9x to both sides

-4x = 20

~Divide -4 to both sides

x = -5

Best of Luck!

Answer:

x = -5

Step-by-step explanation:

3x + 2(x - 9) = 8x + x + 2

-----Distribute left side-----

3x + 2x - 18 = 8x + x + 2

-----Combine like terms-----

5x - 18 = 9x + 2

-----Add 18 to both sides-----

5x = 9x + 20

-----Subtract 9x to both sides-----

-4x = 20

-----Divide -4 to both sides-----

x = -5 <---

Good luck on your exam! :D

Use a proportion to determine the number of children age 5 in a kindergarten class if 80% of a class of 20 children are that age

igor_vitrenko [27]

Answer:

16 children

Step-by-step explanation:

80% of 20 children comes out to 16 children who are of age 5.

If desired, rewrite "80%" as "0.80" and use that 0.80 as the multiplier of 20:

0.80(20 children) = 16 children.

Which of the following is not an asymptote of the hyperbola xy = -42? y = 0 x = 0 y = x

Rainbow [258]

Given:

The equation of the hyperbola is:

$xy=-42$

To find:

The the equation which is not an asymptote of the hyperbola.

Solution:

We have,

$xy=-42$

It can be written as:

$y=\dfrac{-42}{x}$

Equating denominator and 0, we get

$x=0$

So, the vertical asymptotic is $x=0$ .

The degree of numerator is 0 and the degree of denominator is 1.

Since the degree of numerator is greater that the degree of denominator, therefore the horizontal asymptote is $y=0$ and there is no oblique asymptote.

Therefore, $y=x$ is not an asymptote of the given hyperbola and the correct option is C.
