Answer:

x ≤ 13/3

Step-by-step explanation:

4 - 3x ≥ -9

Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 4 from both side:

4 (-4) - 3x ≥ -9 (-4)

-3x ≥ - 9 - 4

-3x ≥ -13

Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:

(-3x)/-3 ≥ (-13)/-3

x ≤ (-13)/(-3)

x ≤ 13/3

x ≤ 13/3 is your answer.

1. According to the Center for Disease Control and Prevention, the breast cancer rate for women has decreased at 0.9% per year b

jeka94

Answer:

a. 199,389

b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.

Step-by-step explanation:

a. Population in 2009 = 192,370

This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389

b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.

Give three pros and cons of getting a pug, and the same for a poodle.

balu736 [363]

Answer:

Step-by-step explanation:

pugs;

pros= Pugs are small in size and thus, making them suitable for small-sized rooms or apartments. Pugs have a friendly and lapdog temperament, get along well with most people and pets. Pugs are low to medium-shed breeds, which implies you are less likely going to be troubled with shedding.

cons= Pugs are prone to various throats, ears, eyes, folds, facial infections, and breathing troubles; hence they will require regular health check-ups. Pug dogs are not highly trainable – it will be difficult to train a pug to do not-so-easy activities even if you hire a professional.

poodle;

pros=They don't shed. Poodles have long hair, instead of fur so they do not shed. ...

They're easy to train. The poodle's intelligence and eagerness to please make them easy to train. ...

They're good with children or other dogs. ...

They make great service dogs or therapy dogs.

cons= Their hair requires some serious maintenance. Because poodles can grow their hair long, they require a lot more maintenance than breeds with short, flat coats. ...

They require a lot of mental stimulation. ...

They can be emotionally sensitive.
