The fourth choice is the correct one. The center of rotation (Q) is always the midpoint between point P and its image P' when rotation is 180°.
Answer:
y=6
Step-by-step explanation:
Differentiate the equation
dy/dx=2x-8
Find the value of x in equation form
2x-8=0
x=8/2=4
Now x=4 is the line of symmetry or the parabola of the quadratic equation.
Plug back x=4 into the equation to find the turning point(minimum value)
y=(4)²-8(4)+22
y=16-32+22
y=6
Since you don't show the graph, all I can do is to tell you how to identify which function is parallel to the x-5y=8.
First let's rearrange the function.
x-5y=8
5y=x-8
y=1/5x-8/5.
Thus, it gives us the slope of the function, which is 1/5.
And the function that is parallel to the graph would have the SAME slope. Which is 1/5. So all you need to do is to find which function has the SAME SLOPE, in this case: 1/5.
Answer:
A. 1
Step-by-step explanation:
12x + 6 = 5x
12x - 5x = - 6
7x = - 6
x = - 6 / 7
Only one solution.
