Find the output, k, when the input, t, is -7.
k = 10t -19
k=?

-89

Step-by-step explanation:

k = 10(-7) - 19

k = -70 - 19

k= -89

Step-by-step explanation:

k=10t-19

t=-7

k

k=10t-19 (given)

k=10.-7-19 (as t=-7)

k=-70-19 (multiply)

k=-(70+19) (factor out negative sign from the expression)

k=-(89) (add)

k=-89

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
