A line is y=12. what is the slope of a line perpendicular to this

1 answer:

7 0

Writing this equations in slope intercept form we get y=0x+12, from which we see the slope I'd 0. the slope of perpendicular lines are negative reciprocals. the negative receipt of 0 would be -1/0, but we know that division by 0 is undefined. there for the slope of the lines are 0 and undefined. sometimes it is useful to say the slope of a vertical line is infinity.

Point A is located at (2, 3) on the coordinate plane. Point A is reflected over the x-axis to form point B and over the y-axis t

Mademuasel [1]

Answer:

Rectangle

Step-by-step explanation:

Well if point A is on (2,3) and you reflect it over the x axis point B would be located at (2,-3).

Then over the y axis point C would be located at (-2,-3), then reflecting that over the x axis point D is (-2,3)

Points

__________

A. (2,3)

B. (2,-3)

C. (-2,-3)

D. (-2,3)

__________

So graphing all these points we get a rectangle.

Because it has 4 sides that are 90 degrees and the sides opposite from each other are the same.

The regular price of the soccer ball is $25. During the sale, it is 20 percent off. Use ratio reasoning to find x, the amount th

Evgen [1.6K]

$ 5 is taken is off the regular price

Solution:

Given that, Regular price of the soccer ball is $ 25

During the sale, it is 20 percent off

Let "x" be the amount that is taken off the regular price

Regular price = $ 25

Discount = 20 percent off

Which means, 20 % of regular price is taken off

x = 20 % of regular price

x = 20 % of 25

$x = \frac{20}{100} \times 25\\\\x = 5$

Thus $ 5 is taken is off the regular price
