Answer:

i hope this helps

Step-by-step explanation:

2x^{2} -16=0

+16        +16

2x^{2} =16

÷2    ÷2

x^{2} = 8

\sqrt{x^{2} }= \sqrt{8}

x= \sqrt{8}

-5x^{2} +9=0

-9          -9

-5x^{2}=-9

÷-5   ÷-5

x^{2} =1.8

\sqrt{x^{2} }= \sqrt{1.8}

x= \sqrt{1.8}

6x^{2} -15=27

+15        +15

6x^{2} =42

÷6   ÷6

x^{2} =7

\sqrt{x^{2} }= \sqrt{7}

x=\sqrt{7}

For the first 8 months at his new job, James gets
Vikentia [17]

James receives a pay increase of 100% per month and has a starting salary of $500.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let b represent the rate of pay increase and a represent the initial pay.

Let us assume that he had received 128000 after the 8 months. hence:

128000 = ab⁸   (1)

Also in the 10th month, he had received 512000, hence:

512000 = ab¹⁰    (2)

From the both equations:

a = 500, b = 2

rate of increase = 200% - 100% = 100%

James receives a pay increase of 100% per month and has a starting salary of $500.
