Y = mx + c
y = 0.5x
y = 0.5*4 = 2
(4,2)
From the recursive rule, you can tell the initial value is 3 and the common ratio is 12. The explicit rule is always
.. (n-th term) = (initial value)*(common ratio)^(n -1)
Subsituting the values you know, you have
.. an = 3*12^(n-1)
(82,82,) (x+y) answer short
The answer is B because Chris and three of his friends is 4. Then, each person paid $9 so 4 x 3 = x.
5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7
