An electrician charges $80 plus $32 per hour. write an equation that represents the total fee y (in dollars) charged by the electrician for a job lasting x hours. find the x and y intercepts. is the value of the x intercept applicable to the electrician? explain. you to whoever answers this question, i am not asking this to cheat off of homework, but to understand the answer for what i am doing. learning from it.

Now, according to the problem, the electrician charges initially $80, that's a constant, it's not related with the number hours, that means it's the initial condition, the constant term.

Then, he charges $32 per hour, that is, this charge depends on the number of hours, it's variable. In other words, it represents a ratio of change.

So, if we apply all this to an equation, it would be

Where, is the ratio of change, is the initial condition (y-intercept), is time and is money.

Therefore, the equation which models this situation is

The y-intercept is for

The x-intercept is for

Observe that x-intercept is at (-2.5,0), which doesn't make sense to the problem, because time cannot be negative.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
