The solution is (3,2) cause both of the lines intersect at one point (which is a solution),and that point is (3,2) :)
Answer:
82
Step-by-step explanation:
2*5 + 9*8 = 10 + 72 = 82
Answer:
14 x 3 = 7 x <u>2</u> x 3 = 42
Step-by-step explanation:
14 x 3 = 42
so, 7 x 2 = 14
then, 14 x 3 = 42
Answer:
y = 4
Step-by-step explanation:
The graph passes through the point (3, 4), which means that the value of the function is 4 when x=3.
T_n = 3 * T_(n-1)
Long way (always works!)
T_5 = 3*T_4,
T_4 = 3*T_3
T_3 = 3*T_2
T_2 = 3*T_1
T_5 = 3*3*3*3*T_1 = 81*T_1 = 81*8 = 648!
Short way (sometimes it works!)
T_n = 3^(n-1) * T_1 (this case is a geometric series of ratio-=3)
T_5 = 3^4*8 = 648
