*PLEASE ANSWER* Which statement about the figure is true?

Mathematics
1 answer:
Ronch [10]3 years ago
6 0

Answer: There are 8 edges and 5 verticles

Step-by-step explanation:

This is a square pyramid. The base is 1 face. The sides that are touching the base and touching at the point that the top is 4 faces altogether. 4+1=5 faces. You can also count the number of faces. (1 face is a square (the base) and the other 4 faces are the sides).

Ok vertices are the points. There are 5 points. Points are where edges touch. (4 vertices are touching the square, the last vertice is at the top of the pyramind)

There are 8 edges. Edges are the literal "edges". You can count. The square on the bottom has 4 edges. The edges touching the top point there are 4 edges. There are 8 edges in total. (4 edges are sides of the square, the other edges are pointing to the top of the pyramind)

The first choice is wrong because it does not have 5 faces.

The second one is correct, the figure has 5 vertices and 8 edges.

The third one is wrong because the figure doesn't have 8 vertices

The last one is wrong it does not have 4 faces.

Complete the following statement.<br> 16/<br> = -8
Rom4ik [11]

16 / x = -8

First, let's divide both sides by x.

16 = -8x

Divide both sides by -8

-2 = x

16 / -2 = -8

Please help asap, it would be much appreciated!! :) Thank you so much!!
LiRa [457]

Statement 1 is false.

While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function.  It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.

Statement 2 is true.

The domain of a function is all the x-values it encompasses.  This function starts at 3 and ends at 8.

Statement 3 is false.

The range of a function is all the y-values it encompasses.  This includes all the y-coordinates, but it does not express the range properly.  The range is [6, 10].

Hope this helps!!

Find an expression which represents the difference when (-x+9y) is subtracted from (-6+4y)
Kay [80]

Answer:

x - 5y - 6

Step-by-step explanation:

- 6 + 4y - ( - x + 9y) ← distribute parenthesis by - 1

= - 6 + 4y + x - 9y ← collect like terms

= x - 5y - 6

Answer:

1. (x+5)(x-1)

6. (3x+4)(x-6)

9. (x+5)(x-5)

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:

Regular: Find two numbers that multiply to C and add to B from ax^2 + bx + c.

x^2+4x-5 = (x+5)(x-1)

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

3x^2-14x-24\\3x^2 - 18x + 4x - 24\\(3x^2-18x)+(4x-24)\\3x(x-6)+4(x-6)\\(3x+4)(x-6)

Difference of Squares: Factor by taking the square root of each term. a^2-b^2 = (a-b)(a+b)

x^2 - 25 = (x+5)(x-5)
