Write y = -0.4x + 0.25 in standard form using integers. please help
multiplying by 20 ... 20y = -8x + 5
8x + 20y - 5 = 0
To convert the given equation, y = -0.4x + 0.25, into standard form (Ax + By = C) using integers, you need to eliminate any decimals. Here's how you can do it:
Step 1: Multiply both sides of the equation by 100 to remove the decimals:
100y = 100(-0.4x + 0.25)
Simplifying:
100y = -40x + 25
Step 2: Rearrange the equation so that the x-term comes before the y-term:
40x + 100y = 25
(Note: I multiplied each term by 100 in step 1, so the coefficient of x became positive 40 instead of negative 0.4. Likewise, the 0.25 became 25 due to multiplication by 100.)
Therefore, the standard form of the equation y = -0.4x + 0.25 in integers is:
40x + 100y = 25
