Y = 15
Because it’s going to every time by 15
For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:

We solve the system of equations.
For this, we use substitution:

From here, we clear the value of x:


Answer:
Maggie is 9 years old
Answer:
13.375
Step-by-step explanation:
you have to add 28 ± 17 = 45 ± 8.857 = 13.375
Answer: 8 weeks
Step-by-step explanation:
Answer:
Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = .
I hope this was the answer u were looking for.
