5x − 8( 1 + 7x ) = −8

Mathematics

xxTIMURxx [149]2 years ago
6 0

Answer:

x = 0

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

5x - 8(1 + 7x) = -8

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

  1. Distribute -8:                              5x - 8 - 56x = -8
  2. Combine like terms:                  -51x - 8 = -8
  3. Isolate <em>x</em> term:                            -51x = 0
  4. Isolate <em>x</em>:                                     x = 0

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it is a solution.</em>

  1. Substitute in <em>x</em>:                    5(0) - 8(1 + 7(0)) = -8
  2. Multiply:                               0 - 8(1 + 0) = -8
  3. Add:                                      -8(1) = -8
  4. Multiply:                                -8 = -8

Here we see that -8 does indeed equal -8.

∴ x = 0 is a solution of the equation.

The table shows the height of a plant as it grows. Which equation in point ­slope form gives the plant’s height at any time
vodka [1.7K]

Answer:

Option A is correct.

y-16=8(x-2) is the equation represent the point slope form gives the plant's height at any time.

Step-by-step explanation:

Point slope intercept form: For any two points (x_1, y_1) and  (x_2, y_2) then,

the general form

y-y_1=m(x-x_1) for linear equations;  where m is the slope given by:

m =\frac{y_2-y_1}{x_2-x_1}

Consider any two points from the table;

let A= (2 , 16) and B =(4, 32)

First calculate the slope of the line AB:

m =\frac{y_2-y_1}{x_2-x_1}=\frac{32-16}{4-2}=\frac{16}{2} = 8

Therefore, slope of the line m = 8

Then,

the equation of line is:

y-y_1=m(x-x_1)

Substitute the value of m=8 and (2, 16) above we get;

y-16=8(x-2)

Therefore, the equation in point slope form which gives the plant's height at any time is; y-16=8(x-2) , where x is the time(months) and y is the plant height (cm)
