Step-by-step explanation:
6x - x² = k
=> x² - 6x + k = 0,
For there to be at least 1 real solution,
The discriminant b² - 4ac must be at least 0.
We have (-6)² - 4(1)(k) >= 0.
Therefore 36 - 4k >= 0, k <= 9.
Hence the largest value of k is 9.
Answer:
2.8 x 10^-3
Step-by-step explanation:
Answer:
5 inches
Step-by-step explanation:
(5 + x)(10 + x) = 6x²
x² + 15x + 50 = 6x²
5x² - 15x + 50 = 0
x² - 3x + 10 = 0
(x - 5)(x + 3) = 0
x = 5, x = -3
We want x to be positive, so x = 5.
Thus, each dimension must be increased by 5 inches.
Answer:
Zero Slope
Step-by-step explanation:
its zero slope because it has no rise
example: rise 0 over 1
Zero slope: 0/1
undefined slope: 1/0
positive slope : 3/4
negative slope: -9/6
