Find all the whole number solutions to the equation a+b+c+d=15

Allushta [10]

Answer:

a=−b−c−d+15

Step-by-step explanation:

Step 1: Add -b to both sides.

a+b+c+d+−b=15+−b

a+c+d=−b+15

Step 2: Add -c to both sides.

a+c+d+−c=−b+15+−c

a+d=−b−c+15Step 3: Add -d to both sides.

a+d+−d=−b−c+15+−d

a=−b−c−d+15

Line A is defined by the equation y=-3x-2

const2013 [10]

THE ANSWER IS: D. y=-3x+11

when two lines are parallel, they share the same slope, which is -3

then plug in the given point into slope intercept form then solve for standard form
