7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
32.5 square feet. If you do the area formula “A=5v13(13) over 2”
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
Answer:
Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):
g(x) = f(2x) = (2x)² = 4x²
Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:
If you're talking about the second part of the question where it asks you which facts you included in your answer, you can choose any of them and it will be counted right.
