Answer:
b. The system is not in echelon form because the system is not organized in descending "stair step" pattern so that the index of the leading variables increases from the top to bottom.
Step-by-step explanation:
The given linear system has a equation which is not in echelon form. The echelon is a system which divides the data into rigid hierarchal groups. The given linear equation in not in echelon form as the leading variables are increased from top to bottom indicating descending stair step pattern.
Based on the graph, point O is the center of the circle.
Segment BC is a chord of the circle that passes through point O, it is a diameter.
Segment OA is a radius of the circle.
The correct statement for this problem is:
<span>Amy walks a distance equal to the diameter, and Fraser walks a distance equal to the radius of the lawn.</span>
Answer:
4 then 3

3 divided by -7/16 will give you your answer
Answer:
a) $8018.78
b) $8056.60
c) 8540 / (1+r)
d) r = (8540/x) - 1 where "x" is the list price.
Step-by-step explanation:
Recall that the:
total price paid = list price + sales tax
total price paid = list price + percent * list price
a) then, in Washington:
8540 = x + 0.065 * x
8540 = x (1 + 0.065)
8540 = x (1.065)
x = 8540 / 1.065
x = $8018.78
b) in Idaho where the sales tax is 6.0% we do a similar calculation but using the decimal form of the percent 0.06:
8540 = x (1 + 0.06)
8540 = x (1.06)
x = 8540 / 1.06
x = $8056.60
c) If the percent tax is "r" then:
we do:
8540 = x (1+r)
x = 8540 / (1+r)
d) solving for "r" instead of for "x":
8540 = x (1+r)
divide by "x" (the list price):
(8540/x) = 1 + r
subtract 1 from both sides:
(8540/x) - 1 = r
