Step-by-step explanation:
For y/x to be as high as possible, y must have the highest possible value and x must have the lowest possible value. (12 and 6)
Hence, y/x < 12/6, which is 2.
For y/x to be as low as possible, y must have the lowest possible value and x must have the highest possible value (10 and 7)
Hence, y/x > 10/7.
Combining the 2 inequalities, we have 10/7 < y/x < 2.
Answer:
D. All real numbers
Step-by-step explanation:
The range of a function is all of the possible x-values (which is easiest to understand if you can view a graph), and the domain of a function is all possible y-values.
So, you could put any x-value into this function (and it would have a corresponding y-value)
The domain [y] is limited, but the range [x] is best described as all real numbers
(if it's hard to remember which is which, d comes before r alphabetically, and x comes before y alphabetically)
1000 meters make 1km. So let's compare that with the question.
1000m=1km
Y=33km
I represented the unknown with Y. Next, you have to cross and multiply. 33 will multiply 1,000 to give 33,000. And Y will multiply 1 to give Y. That will be;
Y=33,000m
33km makes 33,000m.
Hope that helped. Have a nice day
Answer:
d = vt
Step-by-step explanation:
Step 1: Write equation
v = d/t
Step 2: Multiply both sides by t
vt = d
Step 3: Rewrite
d = vt
We want to determine the domain of
any function of the form
is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.
The domain of such functions is all real numbers.
That is for any x, the expression <span>3(2^-x) "makes sense".
Answer: </span><span>The domain is all real numbers</span>
