Write the equation for a line that is perpendicular to the line y = −1 and passing

Mathematics
1 answer:
zheka24 [161]2 years ago
8 0

Answer:

x= 12

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the gradient and c is the y-intercept.

y= -1

y= 0x -1

The given line, y= -1, is a horizontal line as it has a gradient of zero.

A line perpendicular to a horizontal line is a vertical line, and its equation is written as x= ___.

Since the vertical line passes through the point (12, -39), its equation is x= 12.

How can i use substraction to describe divison? <br> I’ll mark u as the brainliest
makvit [3.9K]
Repeated subtraction is a method of subtracting the equal number of items from a larger group. It is also known as division. If the same number is repeatedly subtracted from another larger number until the remainder is zero or a number smaller than the number being subtracted, we can write that in the form of division

Please help. I don’t understand how to do this
Rasek [7]

Greetings from Brasil...

Let's apply the given formula:

A = (1/2)·B·H

The base of this polygon (in this case, the triangle) is B

B = X² - 2X + 6

The height of this polygon is H and is H

H = X + 4

Applying these values (B and H) in the given formula.....

A = (1/2)·B·H

A = (1/2)·(X² - 2X + 6)·(X + 4)

A = (1/2)·(X³ + 2X² - 2X + 24)

A = (X³/2) + X² - X + 12

OR

A = (X³ + 2X² - 2X + 24)/2

Now from here we will be able to tell if they're < , > or =

So, -3.63 is > -3.62

ANSWER: -29/8 > -3.62
