Let x is the <span>unknown number
</span><span>quotient of an unknown number and 12 : x/12
</span><span>49 more than the quotient of an unknown number and 12 : x/12 + 49
so equation:
</span>x/12 + 49 = 53
The answer is 6.
5(4) -2(7)
20-14=6
Answer: D) 6
Focus on the second equation given. The period of that equation is simply the value of b. Because b = 6, this means the period is 6. The function repeats itself every 6 units; in other words, the length of a full cycle is 6 units.
