Given:
The set of ordered pairs in the options.
To find:
The set of ordered pairs which does not represent a function.
Solution:
A set of ordered pairs represents a function if their exist a unique y-value for each x-value.
In option 3, the given set of ordered pair is:
{(−3,−3),(4,1),(−3,3),(2,2)}
Here, we have to y-values -3 and 3 for x=-3. It means the y-value is not unique for x=-3. So, this set of ordered pairs is not a function.
In option 1, 2 and 4, all the x-coordinates are different. It means their exist a unique y-value for each x-value. So, the set of ordered pairs in options 1, 2 and 4 represent a function.
Therefore, the correct opting is 3.
You can write both numbers as fractions:
Dividing by a fraction is the same as multiplying by its inverse, so we have
We can cross-simplify the 10's and we have
Answer:
C = -35
Step-by-step explanation:
C/7=-5
Multiply each side by 7
C/7 *7=-5*7
C = -35
Answer:
f(x) = (8/3)^x
Step-by-step explanation:
Since f increasing, the base value must be greater than 1.
8/3 is the only base value greater than 1.
The base (3/8) would be a decreasing graph because it is less than 1.
The base (-3/8) would result in a wavering graphing passing the x-axis many times. (Because whether the result is negative depends on if x is odd or even.)
in (8/3)^(-x), it is the same as (3/8)^x by applying the negative exponent rule a^(-x) = 1/(a^x).
D
500(x-2)=200x
500x-1000=200x
300x=1000
x=3.333330 or 3 and 1/3
Propeller distance: 3 and 1/3 * 200 = 666.666667 or 666 and 2/3 miles
