Answer:
<em>a=$10</em>
<em>c=$3</em>
Step-by-step explanation:
Step one:
given data
let adults tickets be a
and child tickets be c
so
Roy's purchase
6a+2c=66------1
Elisa's purchase
5a+4c=62-------2
Hence, the system of equations
<em>6a+2c=66------1</em>
<em>5a+4c=62-------2</em>
<em>solving simultaneously</em>
<em>6a+2c=66------1 x2</em>
<em>5a+4c=62-------2 x1</em>
<em />
<em> 12a+4c=132</em>
<em> -5a+4c=62</em>
<em> 7a=70</em>
<em>divide both sides by 7</em>
<em>a=$10</em>
<em />
<em>put a=70 in 1</em>
<em>6(10)+2c=66------1</em>
<em>60+2c=66</em>
<em>2c=66-60</em>
<em>2c=6</em>
<em>c=$3</em>

Excuse me, what is your question ?
Answer:
C.) Supplementary angles.
Step-by-step explanation:
Because angles a and b add up to 180 degrees.
Answer:
neither
Step-by-step explanation:
First differences are 3, 5, 7, 9, and the differences of these (2nd differences) are constant at 2. The degree of the polynomial function describing the sequence is equal to the number of the differences that are constant. Here, that is 2nd differences, so the sequences is described by a 2nd-degree (quadratic) polynomial.
It is not linear (arithmetic) or exponential (first differences have a common ratio).
