1. 20% decrease

2. 16% increase

Explaination:

Question 1.

30 inches to 24 inches is a decrease, because 24 is smaller than 30.

(30-24)/30 * 100%

= 6/30 * 100%

= 20%

Ans: 20% decrease


Question 2.

$126 to $150 is an increase, because 150 is larger than 126.

(150-126)/150 * 100%

= 24/150 * 100%

= 4/25 * 100%

= 16%

Ans: 16% increase

Solve the system of equations by graphing.<br> {y=x-6<br> {y=3x-8<br><br><br> Show work please
Zepler [3.9K]
You should subtract left sides and right sides in order to make y disappeared
and you will have the following:

y - y = (x - 6) - (3x - 8)    =>     0 = x - 6 - 3x - 8     =>     0 = -2x - 14    =>

2x = -14    =>    x = -14/2 = -7

Now you can use -7 in the system and you will get y
y = -7 - 6 = -13

So your answers will be:
x=-7 and y=-13

Answer:

x=-2

Step-by-step explanation:

\frac{1}{6{x}^{2} }  =  \frac{1}{2x}  + \frac{7}{6 {x}^{2} }  \\  \frac{7}{6 {x}^{2} }  -  \frac{1}{6{x}^{2} }  +  \frac{1}{2 {x} }  = 0  \:  \:  \: \:  \:  ( -  \frac{1}{6 {x}^{2} } \: throughout) \\  \frac{6}{6 {x}^{2} }  +  \frac{1}{2x}  = 0  \:  \:  \:  \:  \: (simplify)\\ \frac{1}{ {x}^{2} }  +  \frac{1}{2x}  = 0 \\   \frac{2 {x}^{2} }{ {x}^{2} } +  \frac{2 {x}^{2} }{2x}  = 0 \:  \:  \:  \:  \: ( \times 2 {x}^{2} \:  throughout) \\ 2 + x = 0  \:  \:  \:  \:  \: (simplify)\\ x =  - 2
