<u>First</u><u> </u><u>solut</u><u>ion</u><u> </u><u>:</u>

Say, <u>x = 0</u>

→ 2x + 3y = 4

→ 2(0) + 3y = 4

→ 0 + 3y = 4

→ 3y = 4

→ <u>y = 4/3</u>

  • x = 0, y = 4/3

<u>S</u><u>e</u><u>c</u><u>o</u><u>n</u><u>d</u><u> </u><u>solution</u><u> </u><u>:</u>

Say, <u>x</u><u> </u><u>=</u><u> </u><u>1</u>

→ 2x + 3y = 4

→ 2(1) + 3y = 4

→ 2 + 3y = 4

→ 3y = 4 - 2

→ 3y = 2

→ <u>y</u><u> </u><u>=</u><u> </u><u>2</u><u>/</u><u>3</u>

  • x = 1, y = 2/3

<u>T</u><u>h</u><u>i</u><u>r</u><u>d</u><u> </u><u>soluti</u><u>on</u><u> </u><u>:</u>

Say, <u>x</u><u> </u><u>=</u><u> </u><u>2</u>

→ 2x + 3y = 4

→ 2(2) + 3y = 4

→ 4 + 3y = 4

→ 3y = 4 - 4

→ 3y = 0

→ y = 0 ÷ 3

→ <u>y</u><u> </u><u>=</u><u> </u><u>0</u>

  • x = 2, y = 0

A line segment has endpoints A(4, 8) and B(2, 10). The point M is the midpoint of AB. What is an equation of a line perpendicula
Vera_Pavlovna [14]
I)

The Midpoint M of the line segment AB is found using the Midpoint formula:

M=( \frac{4+2}{2} , \frac{8+10}{2})=(3, 9)

ii)

the slope of the line through A and B is found by the slope formula:

m= \frac{y_1-y_2}{x_2-x_1}= \frac{10-8}{2-4}= \frac{2}{-2}=-1

iii)

the product of the slopes of 2 perpendicular lines is -1, so the slope of the line perpendicular to the line through A and B is -1/(-1)=1

iv) 

the equation of the line with slope 1, which contains point M(3, 9) is found by the slope point form equation of a line:

y-9=1(x-3)

y-9=x-3

y=x+6


Answer: y=x+6

Solve by elimination.<br> 5x-7y=19<br> 7x-7y=-7
SVEN [57.7K]

Answer:

(x,y)=(-13,-12)

Step-by-step explanation:

5x - 7y = 19

7x - 7y = -7  Multiply both sides of the equation by -1

Which then gives you :

5x-7y=19  Sum the equations vertically to eliminate  

-7x+7y=7                 at least on variable

-2x=26      Divide both sides of the equation by -2

X=-13       Substitute the given value of x into the equation 7x - 7y =-7

7 x(-13)-7y=-7 solve the equation for y

y=-12

Thus gives you (-13,-12)

Hope this was useful!!! Sorry if it's wrong.

Can someone help me,it would be appreciated.Thanks!!! :D

The number of pieces of 1/3 foot tall to make a 6 feet skyscraper is 18 pieces.

The model of a skyscraper comes in pieces and each piece is 1/3 feet tall.

After all the pieces are put together the skyscraper is 6 feet tall.

We have to calculate how many pieces were put together to make the 6 feet skyscraper.

Let X be the number of pieces put together to make a 6 feet skyscraper.

Now,

Each piece = 1/3 feet tall.

Since all the pieces together make 6 feet tall, we can write the number of pieces needed to make 6 feet tall as:

X x (1/3) = 6

X = 6 x 3 = 18

Thus, we need 18 pieces of 1/3 foot tall to make a 6 feet skyscraper.

Which of the following equations can be used to find the length of in the
ANEK [815]

The other leg will be LN² = 33² - 11². Then the correct option is A.

<h3>What is a Pythagoras theorem?</h3>

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The hypotenuse is 33 units and one leg is 11 units.

Then the other leg will be

33² = LN² + 11²

LN² = 33² - 11²

Then the correct option is A.

More about the Pythagoras theorem link is given below.

kyle drew tree line segments with these lenngths: 2/4" , 2/3" , 2/6" list the fractions in order from least to graiter
exis [7]
First you find a common denominator, which is 12 ( as 4,3 and 6 all go into 12). So 2/4 becomes 6/12, as 4 multiplied by 3 is 12 and whatever you do to the denominator you must do to the numerator. Then 2/3 becomes 8/12. And 2/6 becomes 4/12. If you put these in order the answer is:

2/6, 2/4, 2/3
