The output k at input t = -7 is -89
Step-by-step explanation:
In order to find the value of a expression on given number, we put the number in given expression in place of independent variable
So,
Given expression is:
[tex]k = 10t-19[/tex]
It is given that the value of t has to be -7
so putting t=-7 in the expression
[tex]k = 10(-7)-19\\k = -70-19\\k = -89[/tex]
Hence,
The output k at input t = -7 is -89
