Answer:

use the equations that are given along with a little imagination.

Step-by-step explanation:

when turning equations into word problems you must use equation that's given.

For example:

•x -3=10

Now lead them into the problem:

-Lyndsey bought 3 less shirts than Riley. Solve for x, How many shirts does Riley have more than Lyndsey if together they have 10 shirts?

HELP ASAP!!

Alex

Answer:

Part A: 1/(2^6) or 1/64

Part B: 1

Step-by-step explanation:

For both parts, you have to keep in mind that a number multiplied by its reciprocal will equal one. For Part B specifically, remember that any number (excluding one) to the 0th power is equal to one

Let A, B and C be sets. Prove that if A ⊆ B ∪ C and A ∩ B = ∅ then A ⊆ C

Studentka2010 [4]

Answer and Solution:

As per the question:

Given:

If $A\subseteq B\cup C$

$A\cap B = \phi$

To prove:

$A\subseteq \C$

Proof:

Suppose $t\in A$

As we know that:

$A\subseteq B\cup C$

Therefore,

$t\in B$ or $t\in C$

Now, if we assume that $t\in B$

Then

$t\in A\cap B$

Since,

$t\in A$ and $t\in B$

But

A and B are disjoint set and $A\cap B = \phi$

Therefore, this is contradictory.

Thus

$t\notin B$

So,

$t\in C$

Every element in the set A is also present in the set C

Therefore, $A\subseteq \C$

Hence, proved.

Which describes the range of the parent absolute value function?

posledela

Parent functions are the most basic functions you can find. Familiarity with the basic characteristics of these simple graphs will help you analyze the shapes of more complicated graphs. So the <em>Parent Absolute Value Function</em> is given by:

$f(x)=\left | x \right | \\ \\ where: \\ \\ \left | x \right |= \left \{ {{x \ if \ x \geq 0} \atop {-x \ if \ x\ \textless \ 0}} \right.$

This function is shown in the figure below. As we can see, the domain of this function is the set of all real numbers while the range is:

$\{y/ \ y\ \textgreater \ 0 \}$
