I need help finding the location of x

Mathematics
1 answer:
KatRina [158]3 years ago
8 0

Answer:

Position of point X on the number line must be X = -27

Step-by-step explanation:

Notice that there are 14 units between W and Y, since the absolute value of their difference is :

| -15-(-29) | = | -15 + 29 | = 14

Now let's write an equation that tells as what is the distance between W and X in terms of WY knowing that we want WX to be 1/7 of WY:

WX=\frac{1}{7} \,*\, 14\\WX= 2

This is telling us that the point X must be located two (2) units to the right of point W. That is W + 2 = -29 + 2 = -27

Position of point X on the number line must be X = -27

(2A)<br> Find f(2x + 4) for f(x) = 1 - x2
Aleksandr-060686 [28]

Answer:

f(2x + 4) = -4x² - 16x - 15

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

Distributive Property

<u>Algebra I</u>

  • Terms/Coefficients
  • Expanding (FOIL)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 1 - x²

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function f(x)]:                                                                          f(2x + 4) = 1 - (2x + 4)²
  2. Expand [FOIL]:                                                                                                  f(2x + 4) = 1 - (4x² + 16x + 16)
  3. (Parenthesis) Distribute negative:                                                                   f(2x + 4) = 1 - 4x² - 16x - 16
  4. Combine like terms:                                                                                          f(2x + 4) = -4x² -16x - 15

Add and simplify 1/5 + 1/10
aliya0001 [1]

In order to add these fractions we have to make a common denominator.

1/5 can turn into 2/10 Its the same thing. And its easier to solve with.

now lets multiply.

\frac{2}{10} × \frac{1}{10}

Now we add across

2 + 1 = 3

------------  

10 + 10 = 10 ( When adding fractions like these the denominator stays the same)

So your answer is...

\frac{3}{10}

Good Luck! :)

If (42)^p = 41^4, what is the value of p?
babymother [125]

First you need to make both bases the same:

Lets remove the ^p and ^4

To make the base of 42 equal to 41, you would have 41^x = 41

X - ln(42) / ln(41) = 1.00648904


Now you have 41^1.00648904(p) = 41^4


Now the bases are equal so we need to set the exponents to equal:

1.00648904(p) = 4

Divide both sides by 1.00648904 to solve for P

P = 4 / 1.00648904

P = 3.97421114
