Lyle and Shaun open a saving account at the same time. Lyle deposits 5100 initially and add $20 per week. Shaun deposits $500 initial and adds $10 per week. Lyle wants to know when he will have the same amount in his savings account as Shaun
After how many weeks of making the additional deposits will Lyle have the same amount of money as Shaun
Write the equations 100 + 20x = 500 + 10x
After 40
weeks Lyle will have the same amount of money as Shaun
The amount of money is

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

30

step-by-step explanation:

times by times

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive
