The volume of a pyramid can be calculated by first calculating the area of the base, then multiply the result to the height of the pyramid and then divide the result by 3.
it goes up 0.8 every time
The graph and the equation show the same
Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:

To solve the system, first we multiply by 2 both sides of the second equation, and we get:

So now the system is

Now we add the two equations, and we get:

So, we get

Now we can substitute this value of y into the eq.(2), and we get:

Answer:
reflect y = cos x over the x-axis
Step-by-step explanation:
When a function is reflected over the x-axis, the transformation is:
y = -f(x)
If it were reflected over the y-axis, the transformation would be:
y = f(-x)
