QuestionFind $y$ from the equation $y=-x-10$ when $x=-1$ . What is the value of $y$ ?

Studdy Solution

STEP 1

Assumptions1. We are given the equation $y={ }^{-} x-10$ . We are asked to find the value of $y$ when $x={ }^{-}1$

STEP 2

To find the value of $y$ , we need to substitute the given value of $x$ into the equation. $y={ }^{-} x-10$

STEP 3

Substitute $x={ }^{-}1$ into the equation.
$y={ }^{-} ({ }^{-}1)-10$

STEP 4

implify the equation. The negative of a negative number is a positive number, so ${ }^{-} ({ }^{-}1)$ becomes $1$ .
$y=1-10$

STEP 5

Subtract $10$ from $1$ to find the value of $y$ .
$y=1-10=-9$ So, when $x={ }^{-}1$ , $y=-9$ .

QuestionFind yyy from the equation y=−x−10y=-x-10y=−x−10 when x=−1x=-1x=−1. What is the value of yyy?

Studdy Solution

STEP 1

Assumptions1. We are given the equation y=−x−10y={ }^{-} x-10y=−x−10 . We are asked to find the value of yyy when x=−1x={ }^{-}1x=−1

STEP 2

To find the value of yyy, we need to substitute the given value of xxx into the equation.y=−x−10y={ }^{-} x-10y=−x−10

STEP 3

Substitute x=−1x={ }^{-}1x=−1 into the equation.y=−(−1)−10y={ }^{-} ({ }^{-}1)-10y=−(−1)−10

STEP 4

implify the equation. The negative of a negative number is a positive number, so −(−1){ }^{-} ({ }^{-}1)−(−1) becomes 111.y=1−10y=1-10y=1−10

STEP 5

Subtract 101010 from 111 to find the value of yyy.y=1−10=−9y=1-10=-9y=1−10=−9So, when x=−1x={ }^{-}1x=−1, y=−9y=-9y=−9.
