Which of the following is the solution to 4 | x + 3 | ≥ 8?A. x ≤ -5 and x ≥ -1
B. x ≥ -1
C. x ≤ -5 or x ≥ -1
D. x ≥ -5 or x ≥ -1

Answers

Answer 1
Answer: First we get rid of the 4 by dividing by it:

4 | x + 3 | ≥ 8 =>
| x + 3 | ≥ 2

Then eliminate the absolute operator like this:

| x + 3 | ≥ 2 =>

-x-3 ≥ 2 or x+3 ≥ 2

Simplify:

-x ≥ 5 or x ≥ -1=>
x ≤ -5  or x ≥ -1

That's answer C
Answer 2
Answer: either  4(x + 3) >= 8  or 4(x + 3) <= -8

4x + 12 >=8                 
4x  >= =4
x >= -1
or 

4x + 12 <= -8
4x <= -20
x <= -5 

Answer is C

Answers

Answer:

x = 15; y = 8; m<Q = 83

Step-by-step explanation:

2x + 7 = x + 22

x + 7 = 22

x = 15


8y - 4 = 4y + 28

4y - 4 = 28

4y = 32

y = 8


2x + 7 + 8y - 4 + m<Q = 180

2(15) + 7 + 8(8) - 4 + m<Q = 180

30 + 7 + 64 - 4 + m<Q = 180

m<Q + 97 = 180

m<Q = 83

Why is 296 divided by 6 equals 48 remainder 8

Answers

basically, 296 divided by 6 means 296 cut up into 6 parts
it doesn't divide equally into whole numbers so we have a remainder
we actually have a remainder of 2, not 8 since we have one 6 in 8 so  it actually is
296/6=49 remainder 2

A school of salmon was swimming in the river 5 feet below the surface. To escape a hungry bear, they went down another 3 feet. What is the position of the salmon now relative to the surface? ​

Answers

The distance of salmon from the surface of the water is 8 feet.

What are mathematical operations?

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

Given that,

The distance of school of salmon for the surface of the river = 5 feet.

Since, to escape a hungry bear, the school of salmon went down to 3 feet.

The position of the salmon to the surface = 5 + 3 = 8 feet.

The required distance of school of salmon from the surface of water is 8 feet.

Answer:

8 Feet below the surface

Step-by-step explanation:

If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.

You can write this as -5 + -3 = -8, assuming that 0 represents surface level.
