Your friend has two jobs. she works a different number of hours each week, so her paycheck for each job is different from week to week. her average weekly paycheck is $110 for job one and $75 for job two. what is her average weekly income if these are her only jobs?

Her average weekly income is $185.

Step-by-step explanation:

Hi, to answer this question we simply have to sum the average weekly paychecks from both jobs.

Mathematically speaking:

Job 1 = $110

Job2= $75

Average weekly income = average weekly paycheck 1 + average weekly paycheck2  

Average weekly income = $110+$75 =$185

Her average weekly income is $185.

Feel free to ask for more if needed or if you did not understand something.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
