Answer:

1) 5.24x10^-1

3) 7.07x10^-6

Step-by-step explanation:

1) Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

2) Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

3) Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

Left to Right

Algebra I

Functions

Function Notation

we have,

Step 1: Define

f(x) = 2x - 5

f(x) = 15

Step 2: Solve for x

Substitute in f(x) [Function]:                                                                             15 = 2x - 5

[Addition Property of Equality] Add 5 on both sides:                                    20 = 2x

[Division Property of Equality] Divide 2 on both sides:                                  10 = x

Rewrite:                                                                                                             x = 10

hence, The solution is : the value of x that makes f(x) = 15, is x = 10.

x2-11x+18=0 need help!

Answers

Answer:

x = 2 or

x = 9

Step-by-step explanation:

x² - 11x + 18 = 0

x² - 9x - 2x + 18 = 0

x(x - 9) - 2(x - 9) = 0

(x - 2)(x - 9) = 0

x - 2 = 0 or x - 9 = 0

x = 2 or x = 9

Thus, x = 2 or 9

-TheUnknownScientist

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 2 and - 9 , since

- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus

(x - 2)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 9 = 0 ⇒ x = 9
