For the equation,
y = 1/2(x+3)^2 -5
The vertice is (-3,-5). Therefore the axis of symmetry is X = -3.
Answer:
The diameter of the circle is 9.
Step-by-step explanation:
Because circumference is equal to 
* d, we can backtrack and use this equation to find diameter. Let's say is equal to 3.14.
28.26 = 3.14d
Divide both sides by 3.14.
9 = d
The diameter of the circle is 9.
Answer:
35 degrees
Step-by-step explanation:
add all the one degrees together
Well 42 divided by 2 is 21. than to double check you can do 21 plus 21 equals 42.
Answers: choice C and choice E
Plugging x = 3 and y = -1 into both equations of choice C lead to a true result (the same number on both sides). This is why the system of equations listed in choice C is one possible answer. Choice E is a similar story.
If your teacher didn't mean to make this a "select all that apply" type of problem, then it's likely your teacher may have made a typo.
