Answer:

X ≤ - 1

Step-by-step explanation:

5 ≥ 4x + 9 ( subtract 9 from both sides )

- 4 ≥ 4x ( divide both sides by 4 )

- 1 ≥ x , then

x ≤ - 1

Which expression is the factorization of x2 + 10x + 212

Montano1993 [528]

Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

${x}^{2} + 10x + 21$

$= {x}^{2} + 3x + 7x + 21$

Next you have to take out the common factors and factorize it :

${x}^{2} + 3x + 7x + 21$

$= x(x + 3) + 7(x + 3)$

$= (x + 7)(x + 3)$

I have one qt of solution diluted out 1:4 How much do I need to add to end up with a final product that’s a 1:10 solution?

LenaWriter [7]

Answer:

1.1352 L

Step-by-step explanation:

L = qt 1.0567

qt = 0.946 L

1:4 = 5

0.946/5 = 0.1892 L one part

0.1892 x 11 = 2.0812 11 parts as 1+10 =11

Answer therefore is subtracting 5 from 11 parts to get the final 6 parts added = 2.0812 - 0.946

= 1.1352 L

Please Help with 31 and 32. I am really confused. Will Select Brainliest Answer.

EastWind [94]

Answer: C, D

Step-by-step explanation:

31 - use the Pythagorean theorem to find the distance

$a^{2} +b^{2} =c^{2}$

a = 45

b = 28

plug in values

$45^{2} +28^{2} =c^{2} = 2809$

c = 53

answer choice C

32 - non linear functions are functions that aren't straight. if a function has anything besides a constant or an x variable to the power of 1, it is not linear

A - this is linear because -18 is a constant

B - this is linear because it only contains constants and an x variable to the power of 1

C - this is linear because it only contains an x variable to the power of 1

D - this is not linear because the x variable is on the bottom of the fraction, so x is to a power of -1

answer choice D
