Answer:

x < -4 or x > 8

On a number line, make two arrows:

1) going towards left from -4 with an open circle at -4

2) going towards right from 8 with an open circle at 8

Step-by-step explanation:

l -4 +2x l -3 > 9

l -4 +2x l > 12

l 2x - 4 l > 12

2x - 4 > 12

2x > 16

x > 8

-2x + 4 > 12

-2x > 8

x < -4

On a number line, make two arrows:

1) going towards left from -4 with an open circle at -4

2) going towards right from 8 with an open circle at 8

Answer:

see below

Step-by-step explanation:

l -4 +2x l -3 > 9

Add 3 to each side

l -4 +2x l -3+3 > 9+3

l -4 +2x l  > 12

We Separate into two inequalities, remembering to flip the negative inequality

 -4+2x>12        or            -4+2x<-12    

Add 4 to each side

  -4+4+2x>12+4   or                  -4+4+2x<-12 +4

2x> 16                      or                     2x< -8

Divide each side by 2

2x/2 > 16/2                  or              2x/2 < -8/2

x > 8    or                                x < -4

To graph we have open circles at 8 going to the right and at -4 going to the left

6a. 1 - 2sin(x)² - 2cos(x)² = 1 - 2(sin(x)² +cos(x)²) = 1 - 2·1 = -1

6c. tan(x) + sin(x)/cos(x) = tan(x) + tan(x) = 2tan(x)

6e. 3sin(x) + tan(x)cos(x) = 3sin(x) + (sin(x)/cos(x))cos(x) = 3sin(x) +sin(x) = 4sin(x)

6g. 1 - cos(x)²tan(x)² = 1 - cos(x)²·(sin(x)²)/cos(x)²) = 1 -sin(x)² = cos(x)²

write an expression for the sequence of operations described below. add s to t, add the result to r, then raise what you have to
Kobotan [32]

Answer:

(s+t+r)^7

Step-by-step explanation:

<u>Sequential Operations </u>

Mathematical operations can be done in sequence or in batches if they are of the same type. For example, we can add many terms in one single operation, but we cannot add and multiply in one go, because there are priorities when dealing with products and sums. Same happens with powers.

In our problem we are required to perform a sequence of operations like follows

Add s to t:

s+t

Add the result to r

s+t+r

Raise what you have to the 7th power

\boxed{(s+t+r)^7}

This is the final result

HELP! Will give Brainliest! Using dimensional analysis, convert 293 cm into m. (1 m= 100 cm)
hram777 [196]
To convert from one unit to another unit, a conversion factor is needed. This is a value that would relate the original unit to the desired unit. We either multiply or divide this value depending on what is being asked in the problem. For this problem, the conversion factor would be 1/100 which means that in 1 m there is 100 cm. We do the conversion as follows:

293 cm ( 1 m / 100 cm ) = 2.93 m
