Pls explain me how to solve this

Answers

Answer 1

Answer: |f(x)| is equivalent to 2 equations
f(x) when f(x) >= 0 OR -f(x) when f(x)< 0

so |x-11| > 4 is equivalent to
x-11 > 4 when x-11 >= 0 OR
-(x-11) > 4 when x-11 < 0

rearrange
x-11 > 4 when x-11 >= 0 we get
x > 15 when x >= 11 ... means x > 11

-(x-11) > 4 when x-11 < 0 we get
x < 7 when x < 11 ...means x < 7

so we have. x < 7 OR x > 11 for this inequality which is not the correct answer

... now... what is solution for |x-11| < 4
you can try to work as above and should come up with the solution just 'the opposite' which is x > 7 OR x < 11 [ 7 < x < 11 ]

then you work for c) and could work or guess for d)

What is 12 divided by 6/7

Answers

What is the easiest way to divide whole numbers to fractions?
Just follow these two easy steps:
1. Multiply the whole number to the denominator of the fraction. In other words, the bottom number of the fraction will be multiplied to the whole number, like this:

12 ÷ 6/7 = n
6
7 x 12
You will have 6/ 84.
2. Simplify.
6 = 1, 2, 3, 6
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 42, 84

the GCF is 6. divide both numbers by 6, so the answer will be 1/14.

You can also get the reciprocal and proceed to multiplication , like this: (12/1 is the fractional form or the whole number 12.)
1/12 x 6/7=n
that makes 6/84 or 1/14.

12 / (6/7) = x
x = 12 * 7/6
x = 14

Choose the three fractions that are less than 4/8 A) 1/2 B) 1/4 C) 5/8 D) 1/3 E) 1/8 F) 3/4

Answers

Answer:

B. 1/4

D. 1/3

E. 1/8

Step-by-step explanation:

4/8 can be represented as 1/2 or a half, therefore, find fractions that are less than half of the denominator.

Doing so will leave you with B, D, and E.

Half of 4/4 is 2/4, 1/4 is less

Half of 3/3 is 1.5/3, 1/3 is less

Half of 8/8 is 4/8, 1/8 is less

Describe how the shape moves from:Frame 1 to Frame 2

Frame 2 to Frame 3

Frame 3 to Frame 4

Answers

Answer:

1. Frame 1 to Frame 2 - Vertical downward translation

2. Frame 2 to Frame 3 - $90^(0)$ counterclockwise rotation

3. Frame 3 to Frame 4 - Vertical upward translation

Step-by-step explanation:

The movement of the shapes from one frame to the other can be described by solid transformations. These are procedures required to change the orientation or size of a given shape. They include: rotation, translation, dilation and reflection.

1. When the shape in frame 1 is translated vertically downwards, it would produce the shape in frame 2.

2. Rotating the shape in frame 2 by $90^(0)$ counterclockwise would move it to the shape in frame 3.

3. Vertical upward dilation would move the shape in frame 3 to that in frame 4.
