<u>Answer-</u>

<em>The axis of symmetry is  x=5</em>

Solution-


The parabolic equation given is,

h(x) = 6x^2-60x+147

Here,  

a = 6, b = -60, c = 147

The equation of the axis of symmetry is,

x=-\dfrac{b}{2a}

Putting the values,

\Rightarrow x=-\dfrac{-60}{2\times 6}\\\\\Rightarrow x=\dfrac{60}{12}\\\\\Rightarrow x=5

Therefore, the axis of symmetry is x=5

Two consecutive integers are such that 3 times the larger exceeds twice the smaller by 34. find the integers.
julsineya [31]

x - a smaller number

(x+1) - a larger number

3(x+1) - 2x = 34

3x + 3 - 2x = 34

x= 31

(x+1) = 32

Given the values of the linear functions f (x) and g(x) in the tables, where is (f – g)(x) positive?
alexandr402 [8]

Comparing the functions, from the tables, it is found that (f - g)(x) is positive in the interval (–∞, 9) .

----------------------

  • For the subtraction function, we simply subtract both functions, thus:

(f - g)(x) = f(x) - g(x)

  • It is positive if f is greater than g, that is: f(x) > g(x).
  • It is a linear function, so one function is greater before the equality, one after.
  • They are equal at x = 9.
  • If x < 9, f(x) > g(x), and thus, (f - g)(x) is positive, which means that the desired interval is:

(–∞, 9)
