Answer:
The distance between Harry’s home and his office? is 15 miles.
Step-by-step explanation:
The speed, distance time formula is:
Given:
Speed (<em>s</em>) = 30 miles/hour
Then the relation between distance and time is:
If Speed was 60 miles/hour the time taken is hours.
Then the relation between distance and time is:
Use the value of <em>d</em> = 30t in (ii)
<em /><em />
Determine the distance as follows:
Thus, the distance between Harry’s home and his office? is 15 miles.
Answer:
C. No, more than one output value x is assigned to the input y-value
Step-by-step explanation:
Given
х у
-3 -2
3 6
0 7
1 7
2 4
3 - 1
Required
State if the table shows x as a function of y
x being a function of y means
i.e. x represents the output while y represents the input of the function
Note that each value of y (input) must be assigned to separate values of x (output) for a function to be established
Having said;
Next step: We have to examine the x and y column
In the y column, the value 7 occurred twice (as shown below)
<em>х у </em>
<em>0 7 </em>
<em>1 7 </em>
<em />
This implies that;
Input 7 gives output of 0 and 1.
<em>Hence, this is not a function.</em>
<em>Option C answers the question.</em>
