The vertex is 10
Basically, 10 is the lowest value for any given set of values for x
um...
Step-by-step explanation:
The last graph. This is because he can’t fold a paper a negative number of times, it’s impossible. Hope this helped :)
7 is 35% of x.
Thus, since 35% = 35/100,
35% of x is 7, so 35/100 * x = 7.
35x/100 = 7
35x=700
x = 20
7 is 35% of 20.
