.21 is decimal form, 21/100 is the fraction in simplest form.
Answer:
$106.75
Step-by-step explanation:
Since the cost of a gallon of oil cost $3.05, we are going to have the equation y = 3.05x, where x represents the number of gallons of oil.
Since the Changs have 35 gallons of oil, the equation would be;
3.05(35) = 106.75
The Changs paid $106.75 for the delivery.
Jack should remove the maximum and minimum weight potatoes from the average weight of the potatoes to compensate for the extremes. Therefore, we are left with a data set of:
8, 9, 11, 7, 7, 8, 9, 7; so n = 8
The sum of these is 66
The average weight of each potato is:
66/8
= 8 ounces
Answer:
slope = 2
y intercept = ( 0 , -1 )
equation:

Step-by-step explanation:
We have given the quadratic expressions and we have to write these expressions in factor form
(a)
It can be written as
Now taking (x+9) as common
(b)
We know the algebraic equation
(c)
(d)
It can be written as
