-3 1/2 -(-12 1/4)
-3 1/2 + 12 1/4
-3 1/2 = -7/2 = -14/4
12 1/4 = 49/4
-14/4 + 49/4 = 35/4
35/4 = 8 3/4
A quick way to convert a mixed number to improper form (improper form makes it alot easier to add, subtract, and more), is like this:
a b/c
((a*c)+b)/c
This will get you the improper form of a fraction.
I hope this makes sense.
-15/-21 -14/x
-15x = -21 * -14
x = -19.6
answer -14c = -19.6 or about -20
answer 3c = .6 or about 1
formula would be
y= 1.2x -3
partial variation means the line doesn't go through (0,0)
Answer:
The y-intercept is 25000 . The intercept is the fixed cost of the doughnut selling company.
Step-by-step explanation:
In the question, it is given that the fixed cost is $25000 and the expense to produce each doughnut is $0.25.
It is required to find and identify the y intercept.
To do so, use the equation derived in previous part of the exercise to interpret the slope. Compare the equation with standard equation of the line.
Step 1 of 1
The total cost of the company is the sum of fixed cost and the expenses for the doughnut, C=0.25x+25000.
Compare the equation with general linear equation y=mx+c.
The y-intercept is 25000 .
The intercept is the fixed cost of the doughnut selling company.
30 country albums because if you divide 45 by 3 you get 15 which is 1/3 of the whole thing. Add another 15 and you get 30 which is 2/3 of it.
