Answer:

Step-by-step explanation:

An absolute value function has the standard form

where h and k are the coordinates of the vertex (the pointy part of the graph) and the absolute value of a indicates whether or not the graph is the same width as the parent graph or if it is steeper or flatter. If the absolute value of a is greater than 1, the graph is steeper; if the absolute value of a is greater than 0 but less than 1 (in other words a fraction less than 1), the graph is flatter than the parent. If the graph is upside down, there will be a negative out in front of the absolute value of a. Because our graph is in fact upside down, we will choose one of the options that has a negative in front of it. The fact that it has moved UP from the origin, but not side to side, means that the k value is a +1.

If you are familiar with an absolute value parent graph, the lines go through each diagonal of the grid perfectly. It appears that our graph is steeper (or slimmer) than that. That means that not only is our graph upside down, it also has an a value greater than 1. Putting those 2 facts to use along with our k value of +1, makes our obvious choice the first one listed.

Rewrite the expression in the form of x ²

Gelneren [198K]

Step-by-step explanation:

Let 8=x

${x}^{ - 4} \times {x}^{3}$

$\frac{1}{ {x}^{4} } \times {x}^{2 + 1}$

$\frac{1}{ {x}^{2 + 2} } \times {x}^{2} \times x$

$\frac{1}{ {x}^{2} } \times x$

$\frac{x}{ {x}^{2} }$

${x}^{ - 1}$

$\frac{1}{8}$

Does experimental probability always give the same results? Explain your answer.

Vanyuwa [196]

Answer:

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

Step-by-step explanation:

The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability

Anwar says that the shape below is a parallelogram. is he correct that a kite is a parallelogram explain

My name is Ann [436]

Short answer: No afraid not.

Opposite sides of a parallelogram must be equal and parallel. The opposite sides of a kit are neither. To make sure you understand, measure the upper left side and the lower right side. The upper left is shorter than the lower right (even though these sides are opposite one another).

It you extend the upper left line upward and do the same thing to the lower right, you will get two lines that meet. No parallelogram will do that.
