Given:
The inequality is
Where, c is the number of cars in the parking lot.
To find:
The graph for the given inequality.
Solution:
We have,
Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.
Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.
In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.
Therefore, the correct option is D.
Answer:
All of the following points lie on the graph of y = 3x except (0,1)
Step-by-step explanation:
The given equation is y = 3x and we have to find which point among the given points doesn't lie on the graph of this equation.

Answer:
y= 4 sinx/2-3
Step-by-step explanation:
y= a sin2πt/T
where : a is the amplitude , t is the time in seconds, and T is a period of wave is seconds.
y=A sin (B(x+C)) +D
amplitude A = 4
2π/B is period = 4
C is the phase shift = -2
D is vertical shifts = -2
now substitute the numbers in the equation :
y= A sin ( B(x+C)) + D
y= 4 sin (4(x-2) -2
y=4sin(4x-8)-2
No solution (D)
Answer = -1
