Step-by-step explanation:
5x + 5y = -5 , when y = 1
5x + 5.1 = -5
5x + 5 = -5
5x = -5 - 5
5x = -10
x = -10/5
x = -2
Answer
(3,-2)
Explanation step by step
<em>y</em><em>=</em><em> </em><em> </em><em>-</em><em>2</em><em>x</em><em>-</em><em>9</em>
<em> </em><em> </em><em> </em><em>=</em><em> </em><em>-</em><em>2</em><em>(</em><em>-</em><em>6</em><em>,</em><em>1</em><em>)</em><em>-</em><em>9</em>
<em>=</em><em> </em><em>(</em><em>1</em><em>2</em><em>,</em><em>-</em><em>2</em><em>)</em><em>-</em><em>9</em>

Answer:
She has $20 + $0.50n in her tip jar.
Step-by-step explanation:
Amount in tip jar at noon = $20
Average amount made from each customer = $0.50
Number of additional customers served after noon = n
Therefore, we have:
Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n
Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n
Therefore, she has $20 + $0.50n in her tip jar.
