Answer:
k = -14
Step-by-step explanation:
We should cross-multiply
9/(k - 7) = 6 / k
9*k = 6 * (k - 7)
9k = 6k - 42
9k - 6k = -42
3k = -42
k = -14
Answer:
-4.01, -4, -7
Step-by-step explanation:
equation:
-x + 6 ≥ 10
substitute each number for x
- (-3.9) + 6 ≥ 10 = (negatives cancel each other out) 3.9 + 6 = 9.9 ≥ 10 (incorrect)
-4 + 6 ≥ 10 = 2 ≥ 10 (incorrect)
- (-4.01) + 6 ≥ 10 = (negatives cancel each other out) 10.01 ≥ 10 (correct)
- (-4) + 6 ≥ 10 = (negatives cancel each other out) 10 ≥ 10 (correct)
-4.01 + 6 ≥ = 1.99 ≥ 10 (incorrect)
-3.9 + 6 ≥ 10 = 2.1 ≥ 10 (incorrect)
-0 + 6 ≥ 10 = 6 ≥ 10 (incorrect)
- (-7) + 6 ≥ 10 = (negatives cancel each other out) 11 ≥ 10 (correct)

Answer:
2 hours
Step-by-step explanation:
using the relationship
distance = speed × time, then
time = 
= 
= 2 hours
For this case, the first thing to do is find the equation of the line correctly and then see which of the inequalities represents the shaded region.
We have then:
5x - y = 2
For x = 0
5 (0) - y = 2
-y = 2
y = -2
For y = 0
5x - 0 = 2
5x = 2
x = 2/5 = 0.4
Therefore the line is:
5x - y = 2
Then, we see that for the point (0, 0)
5x - y ≥ 2
5 (0) - (0) ≥ 2
0 ≥ 2
The inequality is not met, which is correct because this point is not part of the shaded region.
Answer:
The inequality that best is represented by the graph if:
5x - y ≥ 2
