Hello from MrBillDoesMath!

Answer:

Positive x-intercept =  + sqrt(3)

Negative x-intercept = - sqrt(3)


Discussion:

Generally, the x-intercept of a function g(x) occurs where g(x) = 0. In our case this is

g(x) = 0   =>

3x^2 - 9 = 0     =>                         (add 9 to both sides of the equation)

3 x^2      = 9    =>                         (divide both sides by 3)

x^2 = 9/3 = 3  =>

x = +\- sqrt (3)

Positive x-intercept =  + sqrt(3)

Negative x-intercept = - sqrt(3)



Thank you,

MrB

Marrrta [24]

Answer:

The plumber charges £16.50 per hour. this is how to solve it. You minus the callout fee from the total fee which is £167.00- £18.50=£148.50. So you then divide 148.50 by the amount of hours which is 9 hours. so 148.50÷9 = £16.50
