Answer: The probability is 2/5.
Step-by-step explanation: If there are 5 pink bows, 1 blue bow, and 4 purple bows, there are a total of 10 bows in the box. The probability of choosing a purple one is 4/10 (since there are 4 purple bows). 4/10 simplifies to 2/5.
A quadratic expression<span> is any mathematical </span>expression<span> whose power or degree is two. In other words, any </span>expression<span> that uses variables where the highest exponent or the </span>expression's<span> degree is two is a </span>quadratic expression<span>. The </span>expression<span> must have a power of two, no higher nor lower.</span>

It's exponential
Step-by-step explanation:
Answer:
x=2
y=5
Step-by-step explanation:
y= x+3...(1)
y= -x+7...(2)
(1) + (2):
y+y= (x+3) + (-x+7)
2y= (x-x) + (3+7)
2y= 10
y= 5
By substituting y=5 into (1),
we have
5= x+3
x+3=5
x= 5-3
x= 2
