Answer:

Replace all occurrences of y with 6x−3 in each equation.

Replace all occurrences of y in 18x−3y=9 with 6x−3 .

18x−3(6x−3)=9

y=6x−3

Simplify 18x−3(6x−3).

9=9

y=6x−3

Remove any equations from the system that are always true.

y=6x−3

What ate the domain and range of f(x)(1/6)x+2?

never [62]

Answer:

Domain : all real numbers

Range: All numbers greater than 2

Step-by-step explanation:

The shark. (Haha, I'm sorry.)

There are no restrictions on the x. X can be any real number.

The range, however, does have restrictions. The range has to be a number greater than 0.

Why?

Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.

Pattern is -5 then +3, so next number is 46-5 which is 41, and then that plus 3, which is 44
So 41 and 44

Find the area of the rug. DO NOT ROUND. what is the area?

Neporo4naja [7]

Answer:

28.26 ft²

Explanation:

$\sf area \ of \ circle = \pi r^2$

Here given diameter: 6 ft

radius: d/2 = 6/2 = 3 ft

========

area of rug:

$\dashrightarrow \ \pi (3)^2$

$\dashrightarrow \ 9\pi$

$\dashrightarrow \ 9(3.14)$

$\dashrightarrow \ 28.26 \ ft^2$

Convert the following: 110110two to base ten 25ten to base two

blagie [28]

Answer:

110110 in base 2 when converted in base 10 will be equal to 54
25 in base 10 is equal to 1001 base 2

Step-by-step explanation:

Part 1: 110110two to base ten

For conversion from base 2 to base 10 we multiply each digits of given number with powers of 2

$=1*2^5 + 1 * 2^4 + 0 * 2^3 + 1 *2^2 + 1* 2^1 + 0*2^0\\ =1*32+ 1* 16 + 0 + 1*4 + 1*2 +0\\ =32 + 16 +4 + 2\\ = 54$

So 110110two when converted in base 10 will be equal to 54

Part 2: 25ten to base two

For conversion from base 10 to base 2 we will divide the given number with 2 repeatedly and store the remainders until the quotient comes 1. The solution is as follows:

25/2 = 12 remainder 1

12/2 = 6 remainder 0

6/2 = 3 remainder 0

3/2 = 1 remainder 1

Now the remainders will be written in inverse order as:

=1001 base 2

So 25 in base 10 is equal to 1001 base 2

I hope it will help you!

Please help exponents and scientific notation

Anna007 [38]

Alright! When you have a constant to a power times another constant to a power (ex. [x^3 times x^3] ) you simply add the powers and keep the base [x^6]. When you have a power to a power (ex. [(12^3)^3] ) you multiply the powers and keep the base [12^9]. When you have a constant to a power divided by a constant to a power (ex. [ x^2 divided by x^5] ) you subtract the powers and keep the base. It's hard to see the questions, so I'll leave this here for you to use as a guide.
