Answer:
No, because one x-value corresponds to two different y-values.
Step-by-step explanation:
Given a function where x represents an input of a particular value, which gives an output for that particular value inputted as defined by the function, if the function is true and valid, a particular value of input should not give us different values of output.
Thus, from the table given, at x = 5, we have y = 3.
Also, at x = 5, we have y = 2.
Here, one x-value is given us two different y-values. This is not true if a function. We cannot regard the table given as representing a function.
Therefore, the answer is:
No, because one x-value corresponds to two different y-values.
Answer: About or Around 5.85
Step-by-step explanation:
All you do is times 2.34 times 2.5 and you get 5.85
I couldn't work this out on here because I don't know how to get it on the way I want it.

4+-3=1
2(-8)+17=1
Answer:
a = 8
b = 4√5
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
short side/long side = a/16 = 4/a
a² = 64 . . . . . . multiply by 16a
a = 8 . . . . . . take the square root
__
hypotenuse/short side = b/4 = 20/b
b² = 80 . . . . . . . multiply by 4b
b = 4√5 . . . . . take the square root
_____
<em>Additional comment</em>
These relations for the right triangle can be summarized by the rule "the length of a segment that touches the hypotenuse is the geometric mean of the two hypotenuse segments it touches." In the case of b, that means ...
b = √((4)(4+16)) = 4√5
The same sort of relation applies to the unmarked vertical segment on the left:
c = √((16)(16+4)) = 8√5
And, we saw ...
a = √((4)(16)) = 8
Of course, if this rule is to make sense, you need to know that the geometric mean of two numbers is the square root of their product. (In general, the geometric mean of n numbers is the n-th root of their product.)
