The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.

Answer:
Step-by-step explanation:
1 hr=60 min
1 km=0.62137 miles
15 km/min=(15×60) km/hr=900 km/hr=(900×0.62137) miles /hr=559.233 miles/hr
<span>n = 11<span>.
Explanation:
Let m be the number of boxes Mark sells and a be the number of boxes Ann sells.
Since Mark sells 10 less than n, m = n-10. Since Ann sells 2 less than n, a = n-2.
Together, they sold n-10+n-2=2n-12 boxes.
We know that they sold less than n boxes, so our inequality would be
2n-12<n.
To solve this, subtract n from both sides:
2n-12-n<n-n; n-12<0.
Add 12 to both sides:
n-12+12<0+12; n<12.
This means there were less than 12 boxes. The next number down is 11; this woks because Mark sold 10 less than n; 11-10=1. Mark sold at least 1 box.
If n=10, however, 10-10=0; this doesn't work, because Mark did sell at least 1 box. </span></span>

Step-by-step explanation:
Answer:
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Step-by-step explanation:
It's a rectangle so the diagonals are equal
7x - 9 = 2x + 62
Subtract 2x from both sides
5x - 9 = 62
Add 9 to both sides
5x = 71
Divide both sides by 5
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
