Sophie earns a salary of $600per month for working 5hours a day. In May, Sophie worked additional hours at $8per hour and earned $640for the month.

Write an equation to model this situation where tis the number of additional hours she worked in May.

equation = $600 + tx$8 = $640 ; t = 5 additional hours in May

Step-by-step explanation:

Equation = $600 + tx$8/hour = $640

t = ($640 - $600)/$8/hour

t = $40/$8/hour = 5 hours

Equation = $600 + tx$8 = $640 ; t = 5 additional hours in May

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
