Substitute -1 for the variable x.

f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4

Lace edging is sold by the foot for $0.80 or by the foot for $1.99. Which is more expensive

vampirchik [111]

Answer:

$1.99 is more expensive.

Step-by-step explanation:

Given:

One type of lace edging cost $0.80 per foot

Another type of lace edging cost $1`.99 per foot.

We need to find which is more expensive.

In $0.88 where one's place is 0.

In $1.99 where one's place is 1.

By comparing the one's place obviously $1.99 more expensive.

Hope you will understand the concept.

Thank you.

For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

Dahasolnce [82]

The slope of the parallel line is undefined and the slope of the perpendicular line is 0

<h3>How to determine the slope?</h3>

The equation is given as:

x = 1

The above do not have any y value.

This means that the slope of the line is undefined

i.e.

m = undefined

The slope of the parallel line is:

Slope = m

This gives

Slope = undefined

The slope of the perpendicular line is:

Slope =-1/m

This gives

Slope = -1/undefined

Slope = 0

Hence, the slope of the parallel line is undefined and the slope of the perpendicular line is 0
