Answer: 2.)non function 3.)non function 4.) function 5.)non function 6.) non function 7.)function 8.)non function PART B 1.)non function 2.)function 3.) function
Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.
A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))
8*0=0 and 8+0=8
the answer is 8 and 0
Answer: 
Step-by-step explanation:
General equation of ellipse :
Given: Vertices of ellipse : (± 9,0)
Since the vertices are of the form (± a, 0).
i.e. a=9
Thus, the major axis is along x-axis.
Also, foci of the ellipse = (±5,0)
Since, foci is of the form (± c,0), i.e. c=5
Since

Equation of ellipse :

Hence, the required equation :

Answer:
x = 348
Step-by-step explanation:
From the given we can tell it a supplementary angle.
<u>Don't know what supplementary angle is?</u>
<em>Supplementary angle are angles that :</em>
<em>Equal 180 °</em>
<em />
<u><em>Solve: </em></u>
<em>Since,</em>
<em>∠ABD is (0.18x+54)° </em>
<em>∠CBD is (0.07x+39)°</em>
<em />
<em>Thus,</em>
<em>(0.18x+54) + 0.07x + 39 = 180</em>
<em>Group likes terms:</em>
<em>0.25x + 54 + 39 = 180</em>
<em>0.25 + 93 = 180</em>
<em>Subtract 93 from both sides</em>
<em>0.25x = 87</em>
<em>x = 348</em>
<em />
<em>Check Answer:</em>
<em>0.18(348) + 54 + 0.07(348) + 39 </em>
<em>= 180</em>
