Ellen is 11 years older than Maja. Last year Ellen was twice as old as Maja. How old is Maja?

larisa [96]

I believe she is ten because if last year Ellen was twice Maja's age that would be 11 minus one because it was last year. So 10 years older now so whats ten doubled because she was twice her age so 10+10=20. So now we know Maja is 10 and Ellen is 21.

Answer:

we get Rate of change = -3

Step-by-step explanation:

We need to calculate the rate of change for the following data:

x y

-1 7

2 -2

7 -17

10 -26

The rate of change can be calculated using slope formula: $Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}$

From the table, we can take any 2 points

Suppose we take (-1,7) and (2,-2)

We have: $x_1=-1, y_1=7,x_2=2, y_2=-2$

Putting values in formula and finding rate of change

$Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3$
