Hi! So we have to use the Order of Operations, aka PEMDAS so it's:
Parentheses
Exponents
Multiplication/Division
Addtion/Subtraction
Exponent comes first so we'll deal with that. 10^-5=0.00001
And then 7*0.00001=0.00007
Answer:
Part 1 : y = 0.75x
Part 2 : $750
Step-by-step explanation:
Part 1
Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.
Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have
sales price = regular price - discount
y = x - 0.25x
y = 0.75x
Part 2: If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item
Since the sales price, y = 0.75x,and x = regular price = $1000,
substituting x into y, we have
y = 0.75x
y = 0.75($1000)
y = $750
Answer:
20/3 mph (miles per hour)
6.666666666666... mph (miles per hour)
6 2/3 mph (miles per hour)
Step-by-step explanation:
