Solve for x
3x=4y-10
x=(4y-10)/3
solver for y
3x=4y-10
rewrite as 4y-10=3x
4y-10+10=3x+10
4y=3x+10
y=(3x+10)/4
Answer:
D) 3x
Step-by-step explanation:
The difference of adjacent terms is ...
(-7x) -(-10x) = (-7+10)x = 3x . . . . the common difference
Answer:

Step-by-step explanation:
i dont know if im right im just going to say 99% but good luck and sorry if this was late
Bank 1:
$5550 for 5 years with interest 2.3% paid twice a year.
5550 x 1.023^(5 x 2) = 5550 x 1.023^10 = $6967.06 (to 2 decimal places)
(amount of money) x (multiplier - a bit like saying x (100% + 02.3%) because it's increasing the original 100% by 2.3%)^(The time the money is in the account for (years) x how many times a year interest is paid)
6967.06 -5550 = $1417.06 added during the 5 years
bank 2:
$5550 for 5 years with interest 2.2% paid 12 times a year.
5550 x 1.022^(5 x 12) = 5550 x 1.022^60 = $20480.79
20480.79 -5550 = $14930.79 added during the 5 years
comparison:
(bank 1 = + $1417.06 ) < (bank 2 = + $14930.79 )
therefore bank 2 offers the most interest.
hope this helps
