A line is written in standard form Ax + By = 0, where A and B are not

Mathematics
1 answer:
cricket20 [7]3 years ago
5 0

Answer:

A point that must lie on this line is the origin (0,0)

Step-by-step explanation:

we know that

The equation of the line in standard form is equal to

Ax+By=C

where

A is a positive integer

B and C are integer

In this problem

C=0

so

Ax+By=0

That means, that the line represent a proportional relationship between the variables x and y

Remember that in a proportional relationship the line passes through the origin

therefore

A point that must lie on this line is the origin (0,0)

(b) 3(27) = 3(25 + 2)
Leokris [45]

Answer:

3(27) = 3(25 + 2) = TURE

Step-by-step explanation:

Left side: Use long multiplication:

| | 3

× | 2 | 7

Multiply 7 by the digit in the top row:

| | 3

× | 2 | 7

| 2 | 1

Multiply 2 by the digit in the top row:

| | 3

× | 2 | 7

| 2 | 1

| 6 | 0

Add:

Answer: 81

Right Hand: Simplify the following:

3 (25 + 2)

Hint: | Evaluate 25 + 2.

25 + 2 = 27:

3×27

Hint: | Multiply 3 and 27 together.

3×27 = 81:

1. What is the slope of a line that is parallel to the line represented by the equation y=-2/5x + 4/5
lbvjy [14]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  . . . . . . . . .

We are asked to find the slope of the line that is parallel to the line \star~\mathrm{y=-\cfrac{2}{5}x+\cfrac{4}{5}}.

\triangle~\fbox{\bf{KEY:}}

  • Parallel lines have the same slope.

So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.

\circ\!\!\!\star\mathcal{HINT:}

  • The slope is the coefficient of x.

So the slope is

\star~\mathrm{-\cfrac{2}{5}}.

Can you guess the slope of the line that is parallel to the first line?

That's right! The slope is...

\star~\mathrm{-\cfrac{2}{5}}

Hope it helps you out! :D

Ask in comments if any queries arise.

The value of x that will make L and M
Fofino [41]

<em>Greetings from Brasil...</em>

Here we have internal collateral angles. Its sum results in 180, so:

(6X + 8) + (4X + 2) = 180

6X + 4X + 8 + 2 = 180

10X + 10 = 180

10X = 180 - 10

10X = 170

X = 170/10

<h3>X = 17</h3>
