X = 4.8 cm
You have to find the height then use the height to find the x value
21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
Answer:
(-3, 4) is a solution
Step-by-step explanation:
The point (-3, 4) is inside the shaded area of the graph, so is a solution.
You can check in the inequality
y > -2x -3
4 > -2(-3) -3 . . . . substitute for x and y
4 > 3 . . . . . . . true; the given point is a solution
Answer:
is the solution to the equation: 
The statement is true.
Option A is correct.
Step-by-step explanation:
We need to determine if
is the solution to the equation: 
Solving the equation first to find value of x

Combining like terms:

Subtracting 2x on both sides

Now, subtracting 12 on both sides

Divide both sides by -6

So, we get
Therefore we can say that
is the solution to the equation: 
The statement is true.
Option A is correct.
