ycow [4]

Answer:

y = 1/2x + 1

Step-by-step explanation:

m = 1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 1/2(x - 4)

y - 3 = 1/2x - 2

y = 1/2x + 1

Find y if 1030404(3y+36) = 1030403(3y+36).

MA_775_DIABLO [31]

For this case we have the following equation:

$1,030,404 (3y + 36) = 1,030,403 (3y + 36)$

We apply distributive property to the terms within parentheses:

$3,091,212y + 37,094,544 = 3,091,209y + 37,094,508$

We subtract $3,091,209$ and on both sides of the equation:

$3,091,212y-3,091,209y + 37,094,544 = 37,094,508\\3y + 37,094,544 = 37,094,508$

We subtract $37,094,544$ on both sides of the equation:

$3y = 37,094,508-37,094,544\\3y = -36$

We divide by 3 on both sides of the equation:

$y = - \frac {36} {3}\\y = -12$

Answer:

$y = -12$
