When Cabrini is 6, Nikos is 2. When Cabrini is 10, Nikos will be 6.

When Cabrini is 16, Nikos will be 12. When Cabrini is 21, Nikos will be

17. Write and solve an equation to find Nikos’ age when Cabrini is 40.

The equation is N = C - 4 and when Cabrini is 40 Niko will be 36.

Step-by-step explanation:

In order to make an equation that represents their age we need to attribute variables to their ages, we will call Cabrini's age "c" and Niko's age "n". Then we can look at the points that were given to us, we know that Cabrini is older and for every couple of ages that were given to us they're apart in four years, so the equation that represents Niko's age in relation to Cabrini's is:

N = C - 4

When Cabrini is 40 we have:

N = 40 - 4 = 36 years

The equation is N = C - 4 and when Cabrini is 40 Niko will be 36.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
