(820*7)-(480*7)=? This is how to solve the equation
Given:
The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).
Above line is shaded.
To find:
The inequality for the given graph.
Solution:
Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:





Multiply both sides by 2.




Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.

This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.


Therefore, the correct option is D.
Answer:
-2,2
Step-by-step explanation:
Let


We have to find the value of c such that the are of the region bounded by the parabolas =32/3






Now, the area bounded by two curves




![\frac{32}{3}=2[c^2x-\frac{4}{3}x^3]^{c/2}_{-c/2}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B3%7D%3D2%5Bc%5E2x-%5Cfrac%7B4%7D%7B3%7Dx%5E3%5D%5E%7Bc%2F2%7D_%7B-c%2F2%7D)






![c=\sqrt[3]{8}=2](https://tex.z-dn.net/?f=c%3D%5Csqrt%5B3%5D%7B8%7D%3D2)
When c=2 and when c=-2 then the given parabolas gives the same answer.
Therefore, value of c=-2, 2
