Answer:

b     3 was not multiplied by −4

Step-by-step explanation:

The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.

3(p − 4) = 3p + 3 × (-4) = 3p - 12

His attempt is

3(p - 4) = 3p - 4

He did multiply 3 by p, but h did not multiply 3 by -4.

Answer:    b     3 was not multiplied by −4

Answer:

The answer to your question is below

Step-by-step explanation:

1.- (2b - 1) (b + 8) = 0

    2b - 1 = 0           b + 8 = 0

     b = 1/2              b = -8

2.- (x + 3)(x - 12) = 0

     x + 3 = 0            x - 12 = 0

     x = -3                  x = 12

3.- (4b+ 7)(b + 11)

    4b + 7 = 0           b + 11 = 0

      b = -7/4             b = -11

4.- (k - 8)(k + 6)

     k - 8 = 0             k + 6 = 0

    k = 8                   k = -6

5.- (2n + 12)(5n+ 10)

     2n + 12 = 0             5n + 10 = 0

       n = -12/2 = -6          n = -10/5 = -2

6.- (w - 3)(3w - 7)

      w - 3 = 0                3w - 7 = 0

      w = 3                        w = 7/3

7.- (6n - 5)(n - 10)

     6n - 5 = 0                n - 10 = 0

      n = 5/6                   n = 10

8.- (n + 12)((4n + 7)

     n + 12 = 0                 4n + 7 = 0

     n = -12                         n = -7/4

9.- (3b + 4)(5b - 10)

      3b + 4 = 0                 5b - 10 = 0

       b = -4/3                     b = 10/5 = 2

10.- (p - 6)(p + 10)

       p - 6 = 0                  p + 10 = 0

       p = 6                        p = -10

Write the standard form of a line that passes through (1, 1) and (3, 4)
Sophie [7]

Answer:

3x - 2y = 1

Step-by-step explanation:

Step 1:   Find the slope

slope m = (y2 - y1)(/x2 - x1)

 m = (4 - 1)/(3 - 1) = 3/2

Step 1:  Use the formula y = mx + b to solve

This is slope-intercept form of a line.  We have a slope of 3/2, and a point (x, y), which is (1, 1).  Plug those values into the equation above and solve for b (the only variable we are missing

1 = (3/2)(1) + b

   1 = 3/2 + b  

          1 - 3/2 = b

             2/2 - 3/2 = b

                  -1/2 = b

Step 2: Rewrite the formula using the slope and the b value we just calculated

 y = (3/2)x - 1/2

Step 3:  Standard form of a line is ax + by = c, where a is a positive integer, so we rearrange the equation from step 2 to standard form.  

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

 -(3/2)x + y = -1/2     (subtract (3/2)x from both sides)

 

      -3x + 2y = -1       (multiply by 2 to get rid of the fraction on x)

           3x - 2y = 1     (multiply by -1 so a becomes positive)
