K(x) = 6x + 100
k(-5) = 1

to find k(-5) we need to substitute -5 for every x in k (x) and calculate the result:

k(x)=6x+100 becomes:

k(-5)=(6*-5)+100

k(-5)=-30+100

k(-5)=70

plz mark me as brainliest :)

your answer would be b

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
