Answer: a<b
Step-by-step explanation:
Given statement: "a number <em>a</em> is always less than another number <em>b."</em>
<em />
We use "<" or ">" sign to show less than or more than comparison in a mathematical statement.
If <em>a</em> is less than <em>b </em>then it can represented as
<em>a < b</em>
The expressions expresses the relationship between <em>a</em> and <em>b</em> would be:
<em>a < b</em>
The value of variable x of provided quadratic function at h(x) = 18 are 6.56 and -0.13. These points explain solution of the equation.
<h3>What is quadratic formula?</h3>
Quadratic formula is the formula which is used to find the roots of a quadratic equation.The standard form of the quadratic equation is,
ax²+bx+c=0
For the above equation, the quadratic formula can be given as,
![x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
The equation of variable x is given as,
h(x) = 7x²-45x + 12,
The value of h(x) = 18 has to be found out. Put 18 on the place of h(x) in the above equation.
18 = 7x²-45x + 12
0= 7x²-45x + 12-18
0=7x²-45x -6
Find the roots of the equation using the quadratic formula:
![x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\dfrac{-(-45)\pm\sqrt{(-45)^2-4(7)(-6)}}{2(-6)}\\x=6.56,-0.13](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%5C%5Cx%3D%5Cdfrac%7B-%28-45%29%5Cpm%5Csqrt%7B%28-45%29%5E2-4%287%29%28-6%29%7D%7D%7B2%28-6%29%7D%5C%5Cx%3D6.56%2C-0.13)
Thus, the value of variable x of provided quadratic function at h(x) = 18 are 6.56 and -0.13. These points explain the solution of the equation.
