Answer:Kimo is 17 years old and Jennifer is 13 years old.
Step-by-step explanation:
Let x represent Kimo's current age.
Let y represent Jennifer's current age.
Nine years ago, Kimo was twice as old as Jennifer was then. It means that
x - 9 = 2(y - 9)
x - 9 = 2y - 18
x = 2y - 18 + 9 = 2y - 9
In four years, Jennifer will be the same age that Kimo is now. It means that
x = y + 4 - - - - - - - - - 1
Substituting x = 2y - 9 into equation 1, it becomes
2y - 9 = y + 4
2y - y = 4 + 9
y = 13
x = 2y - 9 = 2 × 13 - 9
x = 17
Answer: Domain: (-inf,inf) Range; [-4,inf)
Step-by-step explanation: Domain is x values possible and range is y values possible. Quadratics always have a domain of (-inf,inf) and the range starts from -4 going up infinitely. and if -4 is included then we use a bracket therefore, [-4,inf). Also, infinity always has a parenthesis.
Answer:
B
Step-by-step explanation:
360/6
6 is number of sides
You get 60
Rotate twice to reach 120
Moving F Counter clockwise twice is where B was
It is the 3rd option from the bottom of the 2nd collum.The numbers switch places when the letter changes (from b to b') but they remain the same.
