Answer:

6 faces does it have

Step-by-step explanation:

In any convex polyhedron:

let v be the number  vertices , e is the number of edges and f is the number of faces then;

v+f-2 = e              ....[1]

As per the statement:

If a figure has eight vertices and 12 edges

⇒v = 8 and e = 12

Substitute in [1] to solve for f, we have;

8+f-2 = 12

⇒6+f = 12

Subtract 6 from both sides we have;

f = 6

Therefore, 6 faces does it have

X = y 2 - 1
pochemuha
Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!

If you apply the changes below to the absolute value parent function f(x)=lxl, what is the equation of the new function?
Snowcat [4.5K]

Answer:

f(x)=|x+4|+2

Step-by-step explanation:

The given absolute value function is

f(x)=|x|

This is the base or the parent function.

The transformation f(x)=|x+b|+c will shift the parent function b units to the left and c units up.

From the question, b=4 units and c=2 units.

The new equation is f(x)=|x+4|+2
