Answer:

Step-by-step explanation:

When we use the distributive property for expanding polynomial products, we often use it in the form ...

  (a +b)c = ac +bc

Here, we have ...

  (a +b) = (x -1)   ⇒   a=x, b=-1

  c = (4x+2)

So, the proper application of the distributive property looks like ...

  (a +b)c = ac +bc

  (x -1)(4x +2) = x(4x+2) -1(4x+2) . . . . . different from the work shown

We must conclude ...

  The distributive property was not applied correctly in the first step.

What is 1/4y-1=1/2x+7
Setler79 [48]

Answer:

  a linear equation in x and y

Step-by-step explanation:

The given equation is a linear equation (all variables to the first power) relating the variables x and y. There are an infinite number of values of x and y that will satisfy this equation.

When graphed on an x-y plane, those solution values will fall on a straight line with a slope of 2. It will cross the y-axis at y=32, and the x-axis at x=-16.

passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to ?
goblinko [34]

Answer:

       Equation of line , 5x + 3y = 0

Step-by-step explanation:

The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by \frac{y_2-y_1}{x_2-x_1}

Here points are given by (-3,0) and (-6,5)

Slope=\frac{5-0}{(-6)-(-3)}=\frac{-5}{3}

The slope of parallel lines are same. So slope of required line =\frac{-5}{3}

Equation of a line with slope m passing through origin is given by

                    y =mx

               So equation of line, y=\frac{-5}{3}x\\\\3y=-5x\\\\5x+3y=0

Equation of line , 5x + 3y = 0
