Answer:
There is no solution when x=4
Step-by-step explanation:
By drawing the graph, we can see that x = 4 is a vertical asymptote. An asymptote is a line in which the graph approaches it but never meets it. As a result, the graph will never approach x=4. This means there is no solution at x = 4
Answer:
-75, -73, -71
Step-by-step explanation:
<u>Let the numbers be:</u>
<u>The sum:</u>
- x + 2 +x + x+2 = -219
- 3x = -219
- x = -73
<u>The numbers:</u>
(0,-3) will be the right answer
Answer:the price of a senior citizen's ticket is $5
the price of a student tickets is $7
Step-by-step explanation:
Let x represent the price of a senior citizen's ticket.
Let y represent the price of a student tickets.
On the first day of ticket sales the school sold 7 seniors citizen tickets and 14 student tickets for a total of $133. This means that
7x + 14y = 133 - - - - - - - - - - 1
The school took in $89 on the second day by selling 8 senior citizen tickets and 7 student tickets. This means that
8x + 7y = 89 - - - - - - - - - - -2
Multiplying equation 1 by 1 and equation 2 by 2, it becomes
7x + 14y = 133
16x + 14y = 178
Subtracting, it becomes
- 9x = - 45
x = - 45/-9
x = 5
Substituting x = 5 into equation 2, it becomes
8 × 5 + 7y = 89
40 + 7y = 89
7y = 89 - 40 = 49
y = 49/7 = 7
Step-by-step explanation:
an expression a = a is always true for all possible values of the variable.
therefore, this has an infinite number of solutions.
