On a two week job a repairman works a total of 70 hours. he charges $75 plus $40 per hour. an equation shows this relationship where x is the number of hours and y is the total fee. write the equation. what is the slow and y intercept

the solution is Y= 40•70+75x

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
