-7.x^3=2.7.9
x^3=-18
x=i.(3square root of 18)
Answer:
Therefore the required point where it crosses y-axis is (0 , 4)
Step-by-step explanation:
Given:
...............Equation of line
Intercepts:
The line which intersect on x-axis and y-axis are called intercepts.
There are two intercepts:
x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.
y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.
For a line crosses Y-axis we have,
Put x = 0 in above equation we get
Therefore the required point where it crosses y-axis is (0 , 4)
The answer will be 10 liters
Step-by-step explanation:
Representing inequalities on number line:
First of all we write the inequalities that are to be represented.
Let x represent the elevation of the miner at any time of the day.
The minimum elevation is 6 ft below the sea level. If we consider the sea level as 0 on the number line, the lower limit is -6.
The maximum elevation is 6 ft above the sea level. Hence the upper limit is 6.
The elevation throughout the day is represented by the inequality:
-6 ≤ x ≤ 6 and represented on the line as shown in the picture attached.
Note: The solid end points of the line at 6 and -6 means that 6 and -6 are included in the inequalities.
