Y = x2 - x - 7. what is axis of symmetry

Step-by-step explanation:

To find the axis of symmetry, you use the equation opposite of b, divided by 2(a). Your a will always be the first number, your b your second, and c your third. So your equation would be positive x/2(x^2). I'll let you figure this out on your own.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
