This problem can be converted into a linear algebra problem. The condition is that if the derminant below is not zero, then the system has one solution.
| k 1 1 |
| 1 k 1 | = k^3 - 3k + 2 = 0
| 1 1 k |
Solving for the roots, k = -2, and k = 1.
When k = 1, the three equations are the same so there are infinite solutions.
When k = -2, there are no solutions.
When k /= -2 and k /= 1, there is one solution.
Answer:
x= 4/3
x= -1/2
Step-by-step explanation:
2x (3x-4) +1(3x-4) = 0
Distribute
6x^-8x +1(3x -4) = 0
Multiply by 1
6x^2 -8x +3x-4=0
Brad uses 4.5 cups of cereal and 1.5 cups of mixed nuts because 4.5 cups of cereal is three the amount of mixed nuts:(1.5 cups) and 4.5 +1.5=6 which was the total number of cups of snack mix.
Use Pythagoras theorem
25^2 = 24^2 + x^2
x^2 = 25^2 - 24^2
x^2 = 49
x = 7 feet Answer
