Answer:
10/D that's pretty obvious but whatever
Answer:
Step-by-step explanation:
c = $6.25 + 0.15w
$6.25 represents the fixed cost. it is the cost that does not vary with the number of words
15 cents is the variable cost. it is the cost that varies with the number of words.
to write the equation convert 15 cents to dollars by dividing by 100.
28 because there’s 4 sides to a square and 4 times 7 is 28
The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)
Length of major axis, 2a =8-(-10) = 18
Therefore, a = 9
And length of minor axis, 2b =5-1 =4
Therefore b=2
The formula that we have to use to find the vertices
(h+-a,k)
(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)
Answer:
Step-by-step explanation:
Store A price is 20x-7
store B price is 4(5x+7)
Where x represents the number of items.
Now, observe that the coefficient of both expressions is 20, because 4(5x+7)=20x+7
Remember that the coefficient of the x-variable is always the constant rate of change. Also, the given expressions can be expressed as linear functions
y=20x-7
y=20x+28
Observe that both Stores have already the same rate, which is 20.
Therefore, they have the same rate at any number of items dry cleaned.
What they have different is their initial condition, -7 and +7 respectively, but the rate is the same..
