Answer:
Axis of symmetry= 3
Step-by-step explanation:
f(x)= 2x^2 +12x-4
f(x)=ax^2+bx+c
x=12/2(2)
x=3
f(x)= 2(3)^2+12(3)-14
f(x)= 2(9)+36-14
f(x)=18+36-14
f(x)= 54-14
y=40
Answer:
24 cent
Step-by-step explanation:
If 13 inches of wire cost 39 cent.
We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.
If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.
That is 39/13, which gives 3.
If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.
To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.
8 inches of wire costs 24 cents.
