Answer:
<h2>|−9|, −|−9| and −|9| </h2>
Step-by-step explanation:
Before we choose all the expression that is equal to -9, <em>we must understand that the modulus of a value can return both its positive and negative value</em>. For example, Modulus of b can either be +b or -b i.e |b| = +b or -b
Hence the following expression are all equal ro -9
a) |−9| is equivalent to -9 because the absolute value of -9 i.e |−9| can return both -9 and 9
b) −|−9| is also equivalent to -9. The modulus of -9 is also equal to 9, hence negating 9 will give us -9. This shows that −|−9| = −|9| = −9
c) −|9| is also equivalent to -9. This has been established in b above.
Answer:
x^2-18x+y^2+18y+137=0
express both x and y term in completed square form
(x-9)^2 -81+(y+9)^2-81+137=0
(x-9)^2+(y+9)^2-25=0
(x-9)^2+(y+9)^2=5^2
here the x coordinate of the centre is +9
y coordinate is -9(the negative value of the value associated with the x and y square brackets)
radius=5
Answer:
Its 1
Step-by-step explanation:
A. These angles are not adjacent because they do not share a common line, ray, or segment. They only have point V in common. Note how V is the only letter to show up in the sequences NVP and UVF.
B. These segments are adjacent. We can tell by visually noticing that NVT and TVU share the ray VT. Without the drawing, we can tell they are adjacent because NVT and TVU both have "VT" in them (the order of V and T doesn't matter). See the diagram below.
C. These angles are not adjacent for similar reasoning as choice A above.
D. Same story as choice C and choice A. These angles are not adjacent.
E. Since B is true, this rules out choice E.
==============================
<h3>Final Answer: Choice B</h3><h3>NVT and TVU are adjacent angles.</h3>
