Sandra saves 11% of her salary for retirement. this year her salary was $1,000 more than in the previous year, and she saved $4,620. what was her salary in the previous year?

$41,000

Step-by-step explanation:

To find out how much the salary of Sandra was in the previous year, we first need to find what 4,620 is 11% of.

Now to find the total salary, we first need to multiply 4,620 by 100 then divide it by 11.

Current Salary =

Current Salary = $42,000

Now that we know her current salary, we can simply subtract her current salary by $1,000 to find her previous year salary.

Previous Salary = $42,000 - $1,000

Previous Salary = $41,000

So Sandra's salary the previous year was $41,000.

the answer will be

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
