<h3>Answer:</h3>
x = -2
<h3>Explanation:</h3>
The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.
9 4/9
1. convert 3 1/3 to have a denominator of 9
2. 3 1/3 x 3/3 = 3 3/9
3. 6 1/9 + 3 3/9 = 9 4/9
Answer: This does not represent a function
Step-by-step explanation: To tell if this relation is a function, we can use the vertical line test. In other words, if we can draw a vertical line that passes through more than one point on the graph, then the relation is not a function. In this situation, it's possible to have a vertical line that passes through more than one point so it's not a function.

Answer:
170
Step-by-step explanation:
Given
Tickets = $2 per single and $3 per couple
Total tickets = 365
Total receipts = $925
Required
Number of singles tickets sold.
Let S and C represent singles and couples respectively.
If the total number of tickets sold is 365, then
S + C = 365 --- (1)
Also, if the singles are charged $2 and couples, $3, then
2S + 3C = 925 ----- (2)
Make C the subject of formula in (1)
C = 365 - S
Substitute 365 - S for C in (2)
2S + 3(365 - S) = 925
Open bracket
2S + 1095 - 3S = 925
Collect like terms
2S - 3S = 925 - 1095
-S = -170
Multiply both sides by -1
-1 * -S = -1 * -170
S = 170
Recall that S represents number of single present at the even.
Hence, the number of singles are 170
