Question

K(n)=10n-19 find k(-7)

Answer 1

Answer:

k(- 7) = - 89

Step-by-step explanation:

to evaluate k(- 7) substitute n = - 7 into k(n)

k(- 7) = (10 × - 7 ) - 19  = - 70 - 19 = - 89

Answer 2

Answer:

k(- 7) = - 89

Step-by-step explanation:

N= -7 so K(n)= K(- 7)

to evaluate k(- 7)

k(- 7) = (10 × - 7 ) - 19  = - 70 - 19 = - 89
