The answer is h=4. Trust me.
Answer:
A = 11, B = 25/3, C = -1
Step-by-step explanation:
A linear function has the form:
f(x) = ax + b
(1)
f(3) = 8a + b = 8
f(5) = 5a + b = 9
Using the last 2 equations we can solve for 'a' and 'b'.
8a + b = 8 | 5a + b = 9
We multiply the second one by -1:
8a + b = 8 | -5a -b = -9
And then we add them together:
3a = -1
a =
We then solve for 'b':
5a + b = 9
5(-1/3) + b = 9
b = 9 + 5/3
b = 32/3 = .
We then use this to find A, B, C.
f(x) = (-1/3)x + 32/3
(2)
f(A) = -A/3 + 32/3 = 7
(3)
f(7) = -7/3 + 32/3 = B
25/3 = B
(4)
f(C) = -C/3 + 32/3 = 11
The monthly payment is £114.
Step-by-step explanation:
Step 1:
First, we determine how much the TV costs in total.
The TV is priced at £1,200 and a 20% VAT.
The total cost of the TV
So the total cost of the TV is £1,440.
If a deposit of £300 is paid, the balance to be paid
This £1,140 is to be paid in the next 10 months.
Step 2:
To calculate the monthly cost to be paid we divide the total cost by the number of months.
The cost to be paid every month
So the monthly payment is £114.
