-8x+12 because you distribute the -4
Answer:
See below.
Step-by-step explanation:
x + 2 = x + 2 ⇒ Infinitely Many Solutions
3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions
x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution
Answer:
$540
Step-by-step explanation:
We are given that the initial balance in the bank account is $270.
We are then told that every month $45 is added to the account.
To find the equation that tells us the balance at any point in time assuming no interest is added or money is taken out, we can first understand the constant, y=270.
This gives us the initial value of the balance and any changes to the balance will start from this point.
Let x be the time in months.
if we let y=270 + 45x, we find the value of the function accounting for the addition of money every month.
Assuming money is put in during January; substituting the number of months as x=6 (since it is June), we can find the balance in June.
y=270 +45(6)=540
Hence, the balance in June is $540
Answer:
(3,2)
Step-by-step explanation:
Abcissa = ( 1 + 5 ) / 2 = 3
Ordinate = ( -3 + 7 ) / 2 = 2
T1 = 3
t2 = 2*t1 = 6
t3 = 2*t2 = 12
t4 = 24
t5 = 48
