If you would like to solve 2 * (7 - x) = 3 * (x + 3), you can do this using the following steps:

2 * (7 - x) = 3 * (x + 3<span>)
</span>2 * 7 - 2 * x = 3 * x + 3 * 3
14 - 2 * x = 3 * x + 9
14 - 9 = 3 * x + 2 * x
5 = 5 * x
x = 1

The correct result would be x = 1.

<span>2(7 – x) = 3(x + 3)

14-2x = 3x+9

14-9 = 3x+2x

5 = 5x

5/5 = x

1 = x</span>

All the other stuff, east/west, doesn't matter.

He drives 3 miles north, then later on he drives 4 more miles north:
3 + 4 = 7

The dog show is 7 miles north of his home.

Step-by-step explanation:

<u>Step 1: Define</u>

-2(x - 3) < 4

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide -2 on both sides:                    x - 3 > -2
  2. Add 3 to both sides:                          x > 1

Here we see that any value <em>x</em> greater than 1 would work as a solution to the equation.

The graph shows the function f(x).
FromTheMoon [43]
As shown on the graph the 2 points mentioned have the following coordinates:

A(7,19) & B(11,11), That is A(x₁,y₁) & B(x₂,y₂)

the rate of change between A & B is the slope that is equal to:

slope = rate of change = (y₂-y₁) / (x₂-x₁) ==>(11-19) / (11-7) = (-8) / (4)

Rate of change = -2
