Answer:
[tex]k=-89[/tex]
Step-by-step explanation:
The correct question is
Find the output, k, when the input, t, is -7
. k = 10t-19
we have
[tex]k= 10t-19[/tex]
This is a linear equation in slope intercept form
where
k is the output value
t is the input value
The slope is [tex]m=10[/tex]
The y-intercept (or k-intercept in this problem) is [tex]b=-19[/tex]
To find out the value of k, substitute the value of t in the given equation
so
For t=-7
[tex]k= 10(-7)-19[/tex]
[tex]k=-89[/tex]
