The label on a ceiling lighting fixture warns you to use a lightbulb of 60 watts or less. the voltage to the
lightbulb is 120 volts. an intern calculated how much amperage a bulb of the maximum allowed wattage
will draw. you are checking her work, shown below. if there is an error, what is the first step that has an
error, and why is it an error?

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

a.)the line for function b is steeper

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
