Please Help!! I will give brainliest<br><br> The question is attached below
Rina8888 [55]

Answer:

Step-by-step explanation:

P(x) = \frac{2}{3x-1}

Q(x) = \frac{6}{-3x+2}

P(x) × Q(x) = \frac{2}{3x-1}\times \frac{6}{-3x+2}

                 = \frac{2\times 6}{(3x-1)(-3x+2)}

                 = \frac{12}{(3x-1)(-3x+2)}

P(x) ÷ Q(x) = \frac{2}{(3x-1)} ÷ \frac{6}{(-3x+2)}

                 = \frac{2}{(3x-1)}\times \frac{(-3x+2)}{6}

                 = \frac{(-3x+2)}{3(3x-1)}

The scatter plot shows the systolic blood pressure of people of several different ages. The equation represents the linear model
elena-14-01-66 [18.8K]

Answer: 95 mm Hg


Step-by-step explanation:

Given: The equation represents the linear model for the data is

y=x+95

Since, age is an independent quantity whereas blood pressure is dependent quantity.

Thus, y represents the  the systolic blood pressure of people of several different ages (x).

Now, the age of new born baby =0

Substitute x=0 in the equation , we get y=95

Hence, The systolic blood pressure of new born baby = 95 mm hg

Use what you know about decimals or fractions to explain why (0.2)•(0.002)=0.0004
strojnjashka [21]

Answer:

So any time you are multiplying something, you are making "groups of"

so 3 groups of 2 = 6, 4 groups of 3 = 12

But with decimals or fractions, because they are a value less than zero, the numbers become increasingly small instead of bigger, like standard multiplication.

So for example, 1 group of 1/2 = 1/2

2 groups of 1/4 = 1/2

and so on

hope this helps!
