Answer:
The equations represent circles that result in the same graph.
Step-by-step explanation:
we have
Divide by -10 both sides
-----> equation A
This is the equation of a circle centered at origin with radius
and
Divide by 5 both sides
-----> equation B
This is the equation of a circle centered at origin with radius
equation A and equation B are equal
therefore
The system has infinite solutions, because the equations represent circles that result in the same graph.
4 Americans can arrange themselves in 4! ways.similarly ,3 Frenchmen can arrange themselves in 3! ways.3 Englishmen can arrange themselves in 3! ways.now these 3 groups of same nationality people can be arranged among themselves in 3! ways.so total number of ways = 3!4!3!3!
If you mean 9% of 153 your answer is 13.77
Answer:
3) 5
5) 1
Step-by-step explanation:
substitute the value of 9 for each 'x' in the expression
3) h(9) = 2/3(9) - 1
= 18/3 - 1
= 6-1 or 5
substitute the value of 5 for each 'x' in the expression
5) f(5) = -5² + 6(5) - 4
= -25 + 30 - 4
= 5-4 or 1
