Answer:
D
Step-by-step explanation:
The open circle at the origin means the rightmost piece will have domain x > 0. That is only the case in choices C and D.
The middle piece has a negative slope. That is only the case in choice D.
The appropriate piecewise function is ...
Answer:
Step-by-step explanation:
If it's on the same line, that means that the slope from each point to the other must be the same.
Using the first given points, we can calculate the slope to be:
We can solve for y
We can double check:
Answer:
y = -4/7x + 2
Step-by-step explanation:
So to find the slope intercept form, you have to get the equation to look like: y=mx+b. To do that, you need y on one side and all of the other variable on the other side. So the first thing you have to do is subtract 4x from both sides to get
7y = 14 - 4x
To isolate the y, you have to divide both sides by 7 to get
y = 2 - 4/7x
Now, put this is y=mx+b to get
<u>y = -4/7x + 2</u>

Which is a function?
A relation is of the form
Where and
And for a relation to be regarded as a function, all its x values must be unique. i.e. unrepeated.
Analyzing the options
This is not a function because 0 in multiple times for different y values (range)
i.e. (0,0), (0,1) and (0,2)
This is a function because each of the x values (domains) are unique for different y values (range)
This is a function because each of the x values (domains) are unique for different y values (range)
This is not a function because 1 in multiple times for different y values (range)
i.e. (1,2) and (1,3)
Answer:
You bake 21 chocolate chip cookies.
Step-by-step explanation:
Since the ratio of chocolate chip to oatmeal is 7:5, the ratio is now ?:15. You multiplied the number of oatmeal cookies by 3, which means you must now multiply the number of chocolate chip cookies by the same number. 7 times 3 is 21.
