Angelina factored (x - 4)8 and wrote that it was equal to (x2 - 42)2(x2 + 42). Use complete sentences to explain how you could c

lapo4ka [179]

There are several ways to confirm that the two expressions are equal. One method is to simply factor the first expression and see it you get a result equal to the second expression. An easier method is to set a value for x and substitute it to the two expressions. If the resulting value is that same, this means that the two expressions are equal.

Andrea, Belinda and Chloe spent the evening with their husbands. Eugene was seen with his wife dining at Stake Out but they were

-Dominant- [34]

We can solve the puzzle by simplifying the conditions in the table below:

Husband    Wife Place Visited    Means
Eugene       Chloe Stake Out not Limousine
not David, then Flavian Belinda    Rainbo IV    then Limousine
then David    Andrea    then Water World fun park       Taxi

Therefore, from the given conditions, David and Andrea spent their evening at Water World fun park and they got there by taxi.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 9 sin 7θ

boyakko [2]

Answer:

The given function symmetric about the y-axis.

Step-by-step explanation:

The given function is

$r=9\sin 7\theta$ .... (1)

1. Symmetry about the x-axis: If the point (r, θ ) lies on the graph, then the point (r,-θ ) or (-r, π - θ ) also lies on the graph.

2. Symmetry about the y-axis: If the point (r, θ ) lies on the graph, then the point (r,π - θ ) or (-r, -θ ) also lies on the graph.

3. Symmetry about the origin: If the point (r, θ ) lies on the graph, then the point (-r, θ ) or (r, π + θ ) also lies on the graph.

Put (r, -θ ) in the given function.

$r=9\sin 7(-\theta)=-9\sin 7\theta=-r\neq r$

Therefore it is not symmetric about x-axis.

Put (-r, -θ ) in the given function.

$-r=9\sin 7(-\theta)=-9\sin 7\theta=-r$

Therefore it is symmetric about y-axis.

Put (-r,θ ) in the given function.

$-r=9\sin 7(\theta)=r\neq -r$

Therefore it is not symmetric about the origin.

Find 10-3. Write the subtraction fact two ways.

love history [14]

This is a problem of fact families, but what is fact families? Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by writing the subtraction fact two ways. So we have:

 $10-3$

First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:

Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

So I want to take away 3 triangles, then by taking away 3 what is left? Well the answer is 7:

Δ Δ Δ Δ Δ
Δ Δ

That is, if we subtract 3 from 10 then the result is:

$10-3=7$

Second way. In this subtraction we take the same 10 triangles:

Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

Now I want to take away 7 triangles, then by taking away 7 what is left is 3:

Δ Δ Δ

That is, if we subtract 7 from 10 then the result is:

$10-7=3$
