If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.
The answer is 5. This can be found using the two points given ( (0,0) and (3,15) ) and using the slope formula (15-0 divided by 3-0)
It's a Rational and Integer. Because it's a decimal it can't be anything else.
Find the third iterate, x3, of the function f(x) = 3x + 5 for an initial value of x0 = 1. <span>x1 = 3(1) + 5 = 8 ... x2 = 3(8) + 5 = 29 ... x3 = 3(29) + 5 = 92 </span>
