Find the output, k, when the input, t, is -7−7minus, 7.<br> k = 10t-19k=10t−19

sleet_krkn [62]

The value of k is -89

Explanation:

The given expression is $k=10t-19$

We need to determine the output k, when the input t is -7

<u>Output k:</u>

The value of the output k can be determined by substituting the input $t=-7$ in the expression $k=10t-19$

Thus, we have,

$k=10(-7)-19$

Multiplying the terms 10 and -7, we have,

$k=-70-19$

Simplifying, we get,

$k=-89$

Thus, the value of k is -89
