Answer: No it is not a function

The reason why is because x = 0 goes to multiple y outputs (y = 1 and y = 3 at the same time).

A function can only have one output for any given input.

Side note: Domain = {-2, 0, 5, 7} is the list of x values. Range = {1,3,5,8} is the list of y values.

A certain star is 2.4 x 102 light years from the Earth. One light year is about 5.9 x 1012 miles. How far

Studentka2010 [4]

Answer:

2.5 x $10^{15}$ miles

Step-by-step explanation:

We are given that 1 light year ≈ 5.9 x $10^{12}$ miles so:

4.3 x 10² light year · <u>5.9 x </u> $10^{12}$ <u> miles </u>
1 light year

Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:

≈25 x $10^{14}$

This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:

≈ 2.5 x $10^{15}$ miles

What are the rules for adding and subtracting negative numbers?

Alexeev081 [22]

A negative sign and a negative sign next to each other is a positive sign ex..

-14 - -3
= -14 + 3
= -11

a negative sign and a positive sign next to each other is a positive sign ex..

-14 + -3
= -14 - 3
= -17

the bigger a negative number the smaller it is
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding
the number will become larger

The polygons are similar. Find the value of x.

dmitriy555 [2]

Answer:

x = 30

Step-by-step explanation:

12 : 20 = 18 : x

⇒ 12/20 = 18/x

⇒ 12x = 18 · 20

⇒ 12x = 360

⇒ x = 360 ÷ 12

⇒ x = 30
