9–5(x+4)=3(2–x) help!!!!!1
netineya [11]

Answer:

-17/2 =x

Step-by-step explanation:

9–5(x+4)=3(2–x)

Distribute

9 - 5x - 20 = 6 -3x

Combine like terms

-5x-11 = 6-3x

Add 5x to each side

-5x-11 +5x = 6-3x+5x

-11 = 6+2x

Subtract 6 from each side

-11-6 = 6+2x-6

-17 = 2x

Divide by 2

-17/2 = 2x/2

-17/2 =x

What set or sets of real numbers does -√16 belong to?
Sati [7]

Answer:

Step-by-step explanation:

Well the square root of 16 can be simplified to 4, which can be represented as a fraction: 4/1, so it's not irrational, but rather rational.

Whole numbers are similar to integers, and natural numbers, the only difference is integers includes all real numbers, which do not have a decimal value. So this includes negative numbers, zero, and positive numbers.

Whole numbers include all real numbers, which do not have a decimal value, and are greater than or equal to zero, or in other words, not negative.

Natural numbers include all real numbers, which do not have a decimal value, and are greater than zero, or in other words, positive numbers.

So this number is a integer, and rational number. (since the negative number in front of the radical)

Solve −x−6≤−3 or −4x+3&gt;−1 and write the solution in interval notation.
Readme [11.4K]
[-3,1)

-x-6<_-3 add 6 both sides
-x<_3 divide by negative 1 which means sign switches
x>_-3

-4x+3>-1 subtract 3 both sides
-4x>-4 divide by negative 4 which means sign switches
x<1

1 is the greater bound meaning x can’t be larger than 1

the sign doesn’t include 1 so it’s the parenthesis in interval notation

-3 is the lower bound meaning x can’t be -3 or less than -3 so the interval notation is

The sign includes -3 so it’s brackets in interval notation
