Given:
The equations are:
To find:
The equation that show the relationship between a and c.
Solution:
We have,
...(i)
...(ii)
Equation (i) can be rewritten as:
...(iii)
From (ii) and (iii), we get
Therefore, the required equation is .
(1/2)/(19/6)
1/2 * 6/19
3/19
Answer:
y ≤ -1/5x +1
Step-by-step explanation:
The line had an incline of -1/5 and the intersect with the y-axis is 1, so the line is given by
y = -1/5x +1
The indicated area in graph is below the line, so now you have enough to get the right inequality:
y ≤ -1/5x +1
