"Note how for each (x,y) pair of points given we see that x*y = 60
For instance, the point (4,15) has x = 4 and y = 15 so x*y = 4*15 = 60
Another example: (x,y) = (6,10) means x = 6 and y = 10, so x*y = 6*10 = 60
The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case.
Therefore, the answer is B.) An inverse function is the best model because the products of corresponding x- and y-values are equal."
Answer:
0.75 cents
Step-by-step explanation:
You take...
$2.25 and subtract $1.50 to get 0.75 cents
In-depth...
Start off with taking a dollar away...
2.25 - 1.00 = 1.25
Then take off 0.50 cents...
We know that 0.50 cents are two 0.25 cents
So, we take off one 0.25 cent
1.25 - 25 = 1.00
Then the next 0.25 cents
*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)
<--- it is just adding 25 each time
If we subtract 0.25 cents from a dollar we get...
0.75 cents
Answer:
The x-intercept is x = -2, and the graph approaches a vertical asymptote at x = -3.
Step-by-step explanation:
The given graph is a transformed logarithm function.
The graph is obtained by shifting the parent function three units left.
The vertical asymptote is now
The x-intercept is where the graph intersect the x-axis, which is x=-2
Therefore the last option is correct.
1 whole thing = 6 sixths
3 whole things = 18 sixths
1 third of a whole thing = 2 sixths of it
3 wholes plus 1 third = 18 sixths plus 2 sixths = 20 sixths
Answer: Step-by-step explanation:
57 - 10x = 45
-10x=-12
x=1.2
- 3y + 10x = -5
-3y+10=-5
-3y=-15
y=5
