Mrs. Speas has $138 in her bank account during Week #1. At the end of each week, she deposits $55 into her bank account. a) What is the first term? b) What is the
difference? c) What is the iterative rule for the amount of money Mrs. Speas has
after n weeks? (you are NOT required to simplify)
Plz help I suck at math:-( Please help me pl) will give brainiest to a proper explained answer

Its A

Step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
