Transcript text: Determine if the following equation is linear. If the equation is linear, convert it to standard form ax + by = c.
(-5 + y)² - y² = -11x + 5
Solution
Solution Steps
To determine if the equation is linear, we need to simplify the given equation and check if it can be expressed in the form ax + by = c, where a, b, and c are constants. If it can be expressed in this form, it is linear. If it is linear, we will rearrange the terms to convert it to the standard form.
Step 1: Simplifying the Equation
We start with the equation:
\[
(-5 + y)^2 - y^2 = -11x + 5
\]
Expanding the left side, we have:
\[
(-5 + y)^2 = y^2 - 10y + 25
\]
Thus, the equation becomes:
\[
y^2 - 10y + 25 - y^2 = -11x + 5
\]
This simplifies to:
\[
25 - 10y = -11x + 5
\]
Step 2: Rearranging to Standard Form
Next, we rearrange the equation to the standard form \( ax + by = c \):
\[
11x - 10y = 25 - 5
\]
This simplifies to:
\[
11x - 10y = 20
\]
Step 3: Determining Linearity
Since we can express the equation in the form \( ax + by = c \) with \( a = 11 \), \( b = -10 \), and \( c = 20 \), we conclude that the equation is linear.
