100 POINTS!!! PLEASE HELP!!!

For both functions, we can use the rise over run formula to find the slope. Rise over run uses the following formula:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Function 1 has the points (0,4) and (3,0). Plug the x and y values into the formula:

\frac{0-4}{3-0} =  \frac{-4}{3}

Function 1 has a slope of -4/3.

We can take any two points from Function 2. We'll use (0,5) and (4,8). Plug the values into the formula:

\frac{8 - 5}{4 - 0} =  \frac{3}{4}

Function 2 has a slope of 3/4.

Because the question asks for the steeper slope, we'll convert the slope of Function 1 into a positive number. The slope will now be 4/3. 

Compare the slopes of both functions:

\frac{4}{3} \ \textgreater \  \frac{3}{4}

Function 1 has the steeper slope, -4/3.

5(x+4)= -2(-4-x)+3 <br> what is the answer?
lianna [129]

Answer:

x = -3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

5(x + 4) = -2(-4 - x) + 3

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

  1. Distribute:                                   5x + 20 = 8 + 2x + 3
  2. Combine like terms:                   5x + 20 = 2x + 11
  3. Subtract 2x on both sides:        3x + 20 = 11
  4. Subtract 20 on both sides:        3x = -9
  5. Divide 3 on both sides:              x = -3

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    5(-3 + 4) = -2(-4 - -3) + 3
  2. Simplify:                        5(-3 + 4) = -2(-4 + 3) + 3
  3. Add:                              5(1) = -2(-1) + 3
  4. Multiply:                        5 = 2 + 3
  5. Add:                              5 = 5

Here we see that 5 does indeed equal 5. ∴ x = -3 is a solution of the equation.

And we have our final answer!
