an electrician charges a set fee of $150 for every house call and then charges an additional $70 per hour. write an equation for c, in terms of t, representing the total cost of the electricians services if the electrician spends t hours at the house working.

y = 70x + 150

Step-by-step explanation:

y-intercept: 150

slope: 70x

Let x represent the amount of hours the electrician spent in the house.

C=150+70t

Step-by-step explanation:

In this equation, C stands for the total cost, and t stands for the number of hours worked. Since 150 is a set fee it must be a constant in the equation and to must be added to the hourly cost. 70 must be multiplied by t because the electrician charges 70 dollars for every hour he works. Then, both the set fee plus the hourly fee together equal the total cost.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
