Answer:
I think it is 2/9 or 0.22
Step-by-step explanation:
You know they have the same y intercept, so first you should find the y intercept of the givern equation.
<em>x+2y = 10 </em>
<em>2y = -x + 10 [subtract x]</em>
<em>y = -.5x + 5 [divide by 2]</em>
Now you have the equation in graph form, and know the y intercept is 5.
If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)
now that you have two points, you can use slope formula.
<em>(y2 - y1)/(x2-x1)</em>
<em>(change in y)/(change in x)</em>
so,
<em>(7-5)/(9-0) = 2/9 = 0.2</em>
someone please correct me if i'm wrong:)
Answer:
B. Yes, because it passes the vertical line test.
Step-by-step explanation:
Vertical line test - if a vertical line passes through more than one pone, the relation is not a function
Any vertical line will only pass through one point, so this relation is a function
The relation is a function because it passes the vertical line test
Step-by-step explanation/answer:
Order the numbers from least to greatest!
72, 74, 76, 78, 80, 82, 92, 92
Then calculate the median
First off, What is a median?
The median would be the middle number in the set of numbers
In this case the median would be 79 but let me explain
72, 74, 76, 78, 80, 82, 92, 92,
We cross out every small and greater number from this set until you are left with a number in the set
Thus, the only two left numbers are 78 and 80
Therefore we have to add 78 and 80 then divided by 2
Answer: 79
Answer: 2.5
Step-by-step explanation:
250+200h=300+180h
20h=50
h=2.5
