Answer:
C(X) = 25 + 2x
Step-by-step explanation:
Hello,
John collects vintage baseball cards,
He already has 25 and he collects 2 cards every month.
In x month, he would have
X = 25 + 2x amount of cards
For instance, in 4 months, he would have
X = 25 + 2(4) = 25 + 8 = 33 cards
25 in the equation is a constant since he already has that in stock before considering or calculating what he gets monthly to increase his number of cards.
1.Make 6 1/4 into an irrational fraction. (25/4)
2.Make 3 1/20 into an irrational fraction. (61/20)
3.Multiply the first number (25/4) by the second number's reciprocal (20/61)
4.Get 500/244
5.Simplify to 125/61
6.Turn into mixed number (2 3/61)
*A reciprocal of a fraction is the opposite of a fraction. eg. 2/5 is 5/2 and 6/3 are 3/6*
Original Figure:
Length = 15
Width = 5
Height = 10
Volume = Length*Width*Height
Volume = 15*5*10
Volume = 750
New Figure
Length = 3
Width = 1
Height = 2
Each dimension has been divided by 5 (eg: 15/5 = 3)
Volume = Length*Width*Height
Volume = 3*1*2
Volume = 6
The old volume was 750 and it changes to 6
Notice how 750/6 = 125
Which can be rearranged to 750/125 = 6
Answer: if you divide the old volume by 125, then you get the new volume
Note: the new volume is 125 times smaller than the old volume
Put another way, the old volume is 125 times larger compared to the new volume
The fact that 125 = 5^3 is not a coincidence. If you divide each dimension by some number k, then you divide the volume by k^3
Answer:
-7/4
Step-by-step explanation:
Since the graph is moving down the slope has to be negative we need to write the answer in rise over run rise as in the y range and run as in x range
Here’s how to solve:
3x-15+-9
3x-24
