It has 6 edges

Euler’s Formula: F+V=E-2

Substitute

4+4=E-2

4+4=8

8-2=6

There are 6 edges, hope this helps!!! Good luck!

Devisibility rules for 3, 6, and 9

fenix001 [56]

Answer:

★ Divisibility rule for 3 -

If the sum of all the digits divisible by 3 then the number is divisible by 3.

Here, we take an example for better understanding -

Example 1 - 3525

Add up the digits - 3 + 5 + 2 + 5

→ 15

As, 15 is divisible by 3. So, 3525 is a factor of 3.

★ Divisibility rule for 6 -

A number is to be divisible by 6 , if the number is also divisible by 2 and 3.

Example 2 - 132

Add up the digits = 1 + 3 + 2 = 6

As, 6 is divisible by 2 and it's also divisible by 3. Then, 132 is a factor of 6.

★ Divisibility rule for 9 -

If the sum of all the digits is divisible by 9 then the number is divisible by 9. Just like we'd in 3.

Example 3 - 1052

Add up the digits - 10 + 5 + 2 = 17

As, 17 is not divisible by 9. So, 1052 is also not divisible by 9.

Graph the function f(x)=-4/3x+4

babymother [125]

Answer: Option D is correct.

Step-by-step explanation: An exponential function is in the form of where a is the initial value and b≠ 0 , b >1 .

Given: The function f(x) = y = ......[1]

The domain is all real numbers and the range is y > 0.

y-intercept defined as the graph crosses the y-axis.

Substitute the value of x= 0 in [1] to solve for y;

y = = 4

y-intercept = (0, 4)

End behavior:

when b =3 >1

then;

as ,

therefore, the only graph which represents the function y = is Option D
