Answer:
The answer is y-3
Step-by-step explanation:
Simplify terms
4y-12+9-3y
Combine like terms.
4y-3y=y
-12+9=-3
So the answer is y-3
Answer:
The explicit formula is Tn = 18[(2/3)^(n-1)]
Where n is the term we are looking for
Step-by-step explanation:
Here, we want to get an explicit formula to model the equation
Now, F(2) = 2/3 * f1 = 2/3 * 18 = 12
F(3) = 2/3 * f(2) = 2/3 * 12 = 8
F(4) = 2/3 * F(3) = 2/3 * 8 = 16/3
F(5) = 2/3 * 16/3 = 32/9
Thus, seeing how the equations are progressing, we can definitely see a pattern.
That is Tn = (2/3)^(n-1)(18)
Answer:
x=6√3
Step-by-step explanation:
In 30-60-90 triangles, if the hypotenuse is <em>x</em>, the longest leg is 
, and the shortest leg is 
.
If the longest leg is 6, then 
Multiply by 2,
If x=12,
So, the shortest leg is 6√3.
Answer:
1
Step-by-step explanation:
12(2y-1)=6(y+1)
24y - 12 =6y+6
24y-6y=6+12
18y=18
y=1
