What is the answer to ... -5 - 3w = 7

Mathematics
1 answer:
Ierofanga [76]4 years ago
4 0

Answer:

w = -4

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Equality Properties

Step-by-step explanation:

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

-5 - 3w = 7

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

  1. Add 5 to both sides:                    -3w = 12
  2. Divide -3 on both sides:              w = -4

<u>Step 3: Check</u>

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

  1. Substitute:                    -5 - 3(-4) = 7
  2. Multiply:                        -5 + 12 = 7
  3. Add:                               7 = 7

And we have our final answer!

The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3

Step-by-step explanation:

A symptote is a line that a curve approaches but never touches

  • The vertical asymptote of a logarithmic function is at the zero of the argument
  • f(x) = log(argument) has vertical aymptotes at  argument  = 0

∵ f(x) = 3 ㏒(x + 3)

∵ The argument is (x + 3)

- Equate the argument by zero

∵ x + 3 = 0

- Subtract 3 from both sides

∴ x = -3

- The vertical asymptote of a logarithmic function is at the zero

  of the argument

∴ The vertical asympotote of f(x) is x = -3

The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3

The length of a rectangle is twice it’s width if the perimeter of the rectangle is 54 cm
castortr0y [4]

Width = 9cm

Length = 18cm

<u>Explanation:</u>

Let width = b,

So, length = 2b

Perimeter of rectangle = 2x(length + width)

According to the question,

54cm = 2X(2b + b)\\54cm = 2X(3b)\\27cm = 3b\\b = 9cm

Hence,

Width = 9cm

Length = 18cm

The two sales people for a local advertising firm are Trinity and Jason. Trinity sold $2,330 in ads and Jason sold $1,740. What
pav-90 [236]

The two sales people for a local advertising firm are Trinity and Jason.

Sales amount of Trinity = $2330

Sales amount of Jason = $1740

Total sales of both the people = 2330+1740=4070

The fractional value of Trinity's sales = \frac{2330}{4070}=0.57 or 57%

The fractional value of Jason's sales = \frac{1740}{4070}=0.427 or 43%
