Answer:

The slope is <u>steeper</u> and the line is shifted <u>flatter</u>.

Step-by-step explanation:

I have provided a graph to help illustrate the relationship between these two lines, (The red line is line A which is y = 2x + 4, and the blue line is line B which is y = 4x + 9).

As you can see, the slope does determine the steepness of the lines. This means that line A's slope is going up 2 units and over to the right 1 unit, whereas line B's slope is going up 4 units and to the right 1.

Therefore, if line A is to transform into line B, then its slope will be steeper.

Hope this helps you :)

Also, P.S. I don't know if there are supposed to be more options, so I apologize if flatter does not belong in the second box.

Review the proof step statement 1 cos(2x) = 1-sin^2(x)

Answer:

Option (3)

Step-by-step explanation:

Correct steps for the proof are,

Step Statement

1 cos(2x) = 1 - 2sin²(x)

2 Let 2x = θ

3 x = $\frac{\theta}{2}$

4 $\text{cos}\theta = 1 - 2\text{sin}^2(\frac{\theta}{2} )$

5 $\text{cos}\theta-1 =-2\text{sin}^2(\frac{\theta}{2} )$

6 $1-\text{cos}\theta =2\text{sin}^2(\frac{\theta}{2} )$

7 $\frac{1-\text{cos}\theta}{2} =\text{sin}^2(\frac{\theta}{2} )$

8 $\pm \sqrt{\frac{1-\text{cos}\theta}{2} }=\text{sin}(\frac{\theta}{2} )$

There is a mistake in step 6.

Therefore, Option (3) will be the answer.

Answer:

Diego can choose the 15 items in 128 different ways.

Step-by-step explanation:

Since at the grocery store, Diego has narrowed down his selections to 4 vegetables, 8 fruits, 6 cheeses, and 4 whole grain breads, and he wants to use the Express Lane, so he can only buy 15 items, to determine how many ways can he choose which 15 items to buy if he wants all 6 cheeses the following calculation must be performed:

4 x 4 x 8 = X

16 x 8 = X

128 = X

Therefore, Diego can choose the 15 items in 128 different ways.
