Answer 1

Answer:

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

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.

Answers

$2x-3y=6\n \n 3y=2x-6\n \n \frac { 1 }{ 3 } \cdot 3y=\frac { 1 }{ 3 } \left( 2x-6 \right) \n \n y=\frac { 2 }{ 3 } x-\frac { 6 }{ 3 } \n \n y=\frac { 2 }{ 3 } x-2\n \n \therefore \quad \frac { dy }{ dx } =\frac { 2 }{ 3 }$

This is because:

$y=k{ x }^( n )\n \n \frac { dy }{ dx } =kn{ x }^( n-1 )$

And also because when you differentiate a constant (i.e the number 2), what you always get is the value 0.

The sides of a square are 3 2/7 inches long. What is the area of the square? A.) 9 4/7 square inches

B.) 3 4/7 square inches

C.) 3 4/49 square inches

D.) 9 4/49 square inches

Answers

If you would like to know what is the area of the square, you can calculate this using the following steps:

the area = 3 2/7 inches * 3 2/7 inches = 23/7 * 23/7 = 529/49 =

Is it possible to express every decimal as a fraction (without rounding)? Why or why not?

Answers

Yes, you would just have to change the denominator. For example, .2 would be 2/10 and .201 would be 201/1000. A good rule of thumb is to use place value.

. ____2____ _____0_____ ______1_____
tenths hundredths thousandths

Since the last place value is thousandths my denominator is going to be in the thousands.

If the decimal ends, then always yes.
When you read the decimal, you call it some number of
tenths, or hundredths, or thousandths, or millionths etc.,
and what you call it when you read it consists of the same
words you use when it's written as a fraction.

If the decimal never ends but just keeps going on forever,
then ...
--- if the same group of digits repeats over and over, (as they do in the
decimal form of 1/3, 1/7, and 1/9), then the decimal can be expressed
as a fraction, even though the decimal never ends.
-- if a group of digits doesn't repeat, (as in 'pi' or 'e' for example), then
the decimal is an irrational number The definition of an irrational number
is one that can't be expressed as a fraction.

Create a quadratic polynomial function f(x) and a linear binomial in the form (x − a).Use complete sentences to explain how the remainder theorem is used to determine whether your linear binomial is a factor of your polynomial function

Answers

lets create both equations and :

f(x) = 5x^2 + 1

linear binomial form: x - 4

according to the remainder theorem, x - 4 is a divisor of f(x) if and only if f(4) = 0
f(4) = 5*16 + 1 = 81

hence x - 4 is not a divisor of f(x)
