It dropped by 4.5 means that we have to subtract 4.5 from 9.2

9.2 - 4.5 = 4.7 °C

So 4.7 °C is your answer :D

Which sets are not closed under subtraction

anastassius [24]

If you're referring to the different sets of real numbers, it's the ones that you could try to do subtraction and not get an answer that still in that set.

For example, natural numbers (aka 1, 2, 3, 4, ...) are not, because 7 - 11 = -4 and -4 is not a natural number.

Also, whole numbers (aka 0, 1, 2, 3, 4, ...) has the same issue.

Basically any set of real numbers that doesn't include negative numbers will have this issue.

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-10, 12) and point (5, 3) rounded

Whitepunk [10]

Answer:

<h3>The answer is 17.5 units</h3>

Step-by-step explanation:

Using the distance formula

<h3> $d = \sqrt{ ({x2 - x1})^{2} + ({y2 - y1})^{2} }$ </h3>

the distance between (-10, 12) and (5, 3) is

<h3> $d = \sqrt{ ({5 + 10})^{2} + ({3 - 12})^{2} }$ </h3><h3> $d = \sqrt{ {15}^{2} + ( { - 9})^{2} }$ </h3><h3> $d = \sqrt{225 + 81}$ </h3><h3> $d = \sqrt{306}$ </h3><h3> $d = 3 \sqrt{34}$ </h3>

d = 17.492855

We have the final answer as

<h3>d = 17.5 units to the nearest tenth</h3>

Hope this helps you

Determine the intercepts of the line.<br> x-intercept:( , ) <br> y-intercept:( , )

Nastasia [14]

Answer:

x-intercept: (-7,0)

y-intercept: (0,2)

Step-by-step explanation:

The x-intercept is (-7,0) because on the graph we can see that the line lies on the x-axis on the point (-7,0).

The y-intercept is (0,2) because we can see that the line pass through the y-axis on the (0,2) point.

Hope this helps you :)
