Edy has $450 in her savings account. she deposits $40 each month. juan has $975 in his checking account. he writes a check for $45 each month for his cell phone bill. he also writes a check for $20 each month for his water bill. after how many months will edy and juan have the same amount of money in their accounts?

5 Months

Step-by-step explanation:

$450 + $40x = $975-$45x-$20x  (combine like terms)

450 + 40x = 975 - 65x (perform inverse operations to get only the variable on one side, what is done to one side must be done to the other)

450 + 40x + 65x = 975 - 65x + 65x

450 - 450 + 105x = 975 - 450

105x = 525 (divide both sides by 105)

x=5

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
