What are two different way of factoring -3x-9? Select all that apply

Mathematics
1 answer:
Ghella [55]3 years ago
3 0

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

-3x - 9

Required

Factorize

The options are not given; So, I'll answer on a general term

-3x - 9

Express -9 as -3 * 3

-3x - 9 = -3x - 3 * 3

Then factorize 3 out of the expression as:

-3x - 9 = 3(-x - 3)

Another way is to factor -3 out of the expression as:

-3x - 9 = -3x - 3 * 3

-3x - 9 = -3(x + 3)

Solve the inequality for x. <br> - 2 x - 10 ≥ 4
Inga [223]

Answer:

x ≤ -7

Step-by-step explanation

<em>the steps to solve this are:</em>

1. Add 10 to both sides to get the x value and constant isolated on both sides.

-2x ≥ 14

2. Divide both sides by -2 to get the x value

x ≥ -7

3. Flip the inequality sign since you divided by a negative x-value.

x ≤ -7

Hope i could help! :)

If C(x) is the total cost incurred in producing x units of a certain commodity, then the average cost of producing x units of th
nataly862011 [7]

Answer:

x  =  2000 cameras

Step-by-step explanation:

C(x)     Total cost in producing  x units

C- = C(x) /x   Average cost of producing x units    x > 0

Cannon Precision Instrument

C (x)   Total monthly cost for producing x units of M1 cameras

is    C(x)  =  0.0025x²  + 80x  +  10000

Then average cost of producing x cameras M1 is

C-(x)  =  ( 0.0025x²  + 80x  +  10000)  /x

C-(x)  =   0.0025x  + 80  + 10000/x

Taking derivatives on both sides of the equation

C-´(x)   =  0.0025   -  10000/x²

Then

C-´(x)   = 0

( 0.0025x² - 10000 ) / x²   =  0

0.0025x² - 10000 =  0

x²  =  10000 /0.0025         x²  = 4000000

x  =  2000 cameras

Which of the value of x satisfies the equation below -2x-7=12
Masteriza [31]
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

Explain how the inverse and the contopositivve of a conditional are alike and how they are different
anygoal [31]

Answer:

See explanation!

Step-by-step explanation:

The contrapositive of a conditional is similar to, yet different from, the inverse of the conditional.

The best way to explain this is to create an example. You should start by creating a conditional; you can then form the conditional's inverse and contrapositive.

<u>Here is an example:</u>

Conditional: If C, then D. (starting statement)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

<u>Based on the information from the example, you can conclude:</u>

<u>Primary Similarity:</u>

Both the contrapositive and the inverse are opposites of the conditional (both contain not, implying something would not happen under the given circumstances, rather than something would happen under those circumstances).

<u />

<u>Primary Difference:</u>

The contrapositive is a reversed version of the inverse; this causes them to most commonly have different meanings.

I am sure you could find more similarities/differences, but these were the two that stood out to me the most!

I hope this helps! :)
