Question

Find the output, kkk, when the input, ttt, is -7−7minus, 7.
k = 10t-19k=10t−19

Answer 1

`k=-89`

Explanation:

The correct question is

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

we have

`k= 10t-19`

This is a linear equation in slope intercept form

where

k is the output value

t is the input value

The slope is
`m=10`

The y-intercept (or k-intercept in this problem) is
`b=-19`

To find out the value of k, substitute the value of t in the given equation

so

For t=-7

`k= 10(-7)-19`

`k=-89`
