Step-by-step explanation:
The slope of the above line = -2
slope of the line perpendicular to the above line = 1/2
If it passes through point (4,-3) , it's equation
A = 1, B = -2 and C = -10
A+B+C= 1+(-2)+(-10)
= 1-2-10
= 1-12
= -11
Answer:
-4
Step-by-step explanation:
To get this answer you must first get the VAT cost which we will get with the following steps.
First make the percent a decimal to do so move the . over to the left two times
Resulting in .20 now multiply it with 800
800(.20)=160
Now add 160 to 800
800+160=960
So the total cost for this TV is £960
