The amount in dollars an electrician charges in terms of the number of hours worked is represented by the function y=22x+42.
from the function, identify all the phrases that hold true for the situation.

Step-by-step explanation:"

The electrician charges an initial fee of $42", AND "The electrician charges $22 for every hour worked" is true.

The equation is y=22x+42. The formula is y=mx+b.m is the slope, or is this case, the number of dollars for every "x", which is the number of hours worked. So you have to pay $22 for every hour the electrician works.b is the y-intercept, or the amount it starts with, in this case, you have to pay a fee of $42 even when the electrician worked 0 hours. This is because $42 is the amount it starts with.On a graph, the line will start at (0,42) because that is when you start paying. And then it will increase by 22 for each hour, so the next coordinate would be (1,64).

hi there, your answer is:

the electrician charges an initial fee of $42, AND "the electrician charges $22 for every hour worked is true.

the discriminant is 64 + 4*1*12 = 112

this is prime.
