Slope of 4 means you add 4 to the y and 1 to the x so the answer is (-1,9)
Answer:
I assume that the function is:

Now let's describe the general transformations that we need to use in this problem.
Reflection across the x-axis:
For a general function f(x), a reflection across the x-axis is written as:
g(x) = -f(x)
Reflection across the y-axis:
For a general function f(x), a reflection across the y-axis is written as:
g(x) = f(-x)
Then a reflection across the y-axis, and then a reflection across the x-axis is just:
g(x) = -(f(-x)) = -f(-x)
In this case, we have:

then:

Now we can graph this, to get the graph you can see below:
Answer:
The volume of the metal used is 5277.9 cm³.
Step-by-step explanation:
The volume of a cylinder is given by:

Where:
r: is the radius
h: is the height = 50 cm
The volume of metal (
) can be found by subtracting the internal volume (
) from the external volume (
):

The external radius is given by the sum of the internal radius with the tickness:

Hence, the volume is:

Therefore, the volume of the metal used is 5277.9 cm³.
I hope it helps you!
Answer:
x=-1
Step-by-step explanation:
-5x=5
-x=1
x=-1
or solve this way
-5x=5
5x=-5
x=-1
The slope would be 2. the equation to find slope is m= y2-y1/x2-x1 , so 0- -4 is 4, and 2-0 is 2, and 4/2 is 2.
