Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.

Answers

Answer 1
I am not sure I’m sorry
Answer 2

Answer:

-3 & -5

Step-by-step explanation:

let the two numbers be x and y

x + y = -8. sum of the numbers is -8

x - y = 2. difference(-) of the numbers is 2

now we add the two equations

x + x + y - y= -8 + 2

2x = -6

x = -6/2. = -3

substitute value of x in second equation to get y

-3 - y = 2

-y = 2 + 3

-y = 5

y = -5

• The y-intercept represents a starting salary of $ ? for a new employee. • The slope represents an additional $ ? in salary for each additional year of employment. • If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ? x + ? . • If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ? .

Answers

Answer:

Can you show the graph please?

Step-by-step explanation:

Answer:

300

Step-by-step explanation:

If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ?.

Let $e for new empolyee.

Let $s for slope for salary.

We know if the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ?

y = ? the question mark will represent x.

Because $35,000 is the only number, that will be our main goal.

So $35 in shorten, added 25, 20. Which is 45.

With that we do +200 - 45. 155.

So 45+255=300

Answer: 300
