The second table, because -1 x 3 = -3
-3 - 3 = -6 therefore, the second table matches the equation y= 3x -3
Y = 3x-5
(3, ) - your x is 3 in that case, y = 3*3-5 = 4 - answer (3,4)
(4, ) - your x is 4, y = 4*3-5 = 7 - answer (4,7)
( ,10) - your y is 10:
10 = 3x - 5
3x = 15
x = 5 - answer (5, 10)
Solution pairs - (3, 4); (4, 7); (5, 10)
12 girls for every 5 boys
boys is second so it shouldb be indenomenaotr (bottom)
girls/boys
12girls/5boys=2.4girls/boy
answer is B
You would divide 34 by 40, giving you the decimal number of:
0.85
you would then multiply by 100, moving the decimal point two places to the right.

Answer:
A 1/81
Step-by-step explanation:
f(x) = 9^x
Let x=-2
f(-2) = 9^-2
The negative takes it down to the denominator
f(-2) = 1/ 9^2
f(-2) = 1/81
