Answer:
1 : 2
Step-by-step explanation:
Twelve in total tried out for the cheering squad. The students selected were only 6 so the ratio would be 6 : 12 is shortened to 1 : 2.
Answer
x - 1 + 6x^2
Step-by-step explanation:
Write al the sides together: 2x + 5 + x^2 - 6 + 4x^2 + 2x + x^2 - 3x
Then organize the terms: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
Simplify: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
2x + 2x -3x = 4x - 3x = 1x or x
x + 5 - 6 + x^2 + x^2 + 4x^2
5 - 6 = -1
x - 1 + x^2 + x^2 + 4x^2
x^2 + x^2 + 4x^2 = 2x^2 + 4x^2 = 6x^2
x - 1 + 6x^2
For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000
n = 0
V(0) = a * b^0 = 3500
a = 3500
V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76
V(n) = 3500 * 0.76^n
We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660
And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536
Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
Answer:
Equation I , II and V.
Step-by-step explanation:
Number II:L
0.5(8x + 4) = 4x + 2 Distributing the 0.5 over the parentheses:
4x + 2 = 4x + 2
The 2 sides of this equation are identical so we can make x any value to fit this identity. That is there are Infinite Solutions.
I and V are also included:
I: 12x + 24 = 12x + 24.
V left side = right side.
