Answer:

Step-by-step explanation:

Use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-7 - 5)^2 + (-7 - 9)^2}\\d = \sqrt{(-12)^2 + (-16)^2}\\d = \sqrt{144 + 256}\\d = \sqrt{400} = 20$

For what values of y does the binomial 5y−7 belong to the interval (−5, 13)?

maw [93]

Answer: y should be in the interval (0.4, 4)

Explanation:

The binomial 5y - 7 is in the interval (-5, 13) if and only if

-5 < 5y - 7 < 13

Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that

2 < 5y < 20

Then, we divide both sides by 5 to get the following inequalities

0.4 < y < 4

Hence y should be in the open interval (0.4, 4).

Can anyone help out with the first question so I can get an idea with the others?

Oksanka [162]

As you can see, the first number line is divided into tenths (0.1, 0.2, 0.3). So, put 8.152 in between 8.1 and 8.2.

Then, the ends of the next number line should be 8.1 at the start, and 8.2 at the end. You keep going smaller to find the exact spot. So, move 5 places inwards and place the 8.153, between 8.15 and 8.16.

Afterwards, the ends of the last number line should be 8.15 and 8.16. Now, it is divided into thousandths. So, find the third spot. Now, it should be 8.153 correctly labeled.
