Chess club earnings are $40 per month and will increase at a rate of 2.5% each month. Which function describes this situation?
Question 19 options:

y=40(.75)x

y=40(0.975)x

y=40(1.025)x

y=40(1.25)x

What is the value of x in the equation 2(x-4) = 4(2x + 1)?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Ineed the solution to this problem and the steps.
