Question about SoftMath Algebrator - Algebra Homework Solver (689076614429)

This is an equation of a straight line, and we can easily find the the coordinates where this line intersects the axis in following ways:-

**for x-axis:-**

put y=0, 4x+2*0=8

4x =8

x =8/4

x =2

so intersection coordinates ate (2, 0)

**for y-axis:-**

put x=0, 4*0+2y=8

2y =8

y =8/2

y =4

so intersection coordinates ate (0, 4)

Thanks

y = x+1

y = (4) + 1

y = 5

y = x + 1

y = (-4) + 1

y = -3

2y - 2 = 2x

2y - 2 = 2 (4)

2y - 2 = 8

2y - 2 + 2 = 8 + 2

2y = 10

2y/2 = 10/2

y = 5

2y - 2 = 2(-4)

2y - 2 = -8

2y -2 + 2 = -8 + 2

2y = -6

2y / 2 = -6 /2

y = -3

The results are the same, implying that they are the same line.

Why?

2y - 2 = 2x

2y - 2 + 2 = 2x + 2

2y = 2x + 2

divide everything by 2

y = x + 1

Good luck,

Paul

Both should work.

16x - 2y = 16

4x - 2y = -8

-----------------

12x = 24

x = 2

y = 8

2y=4x + 8

y = 2x + 4

16x - 2(2x + 4) = 16

16x - 4x -8 = 16

12x = 24

x = 2

y = 8

Good luck.

-----------------

12x = 24

x = 2

y = 8

2y=4x + 8

y = 2x + 4

16x - 2(2x + 4) = 16

16x - 4x -8 = 16

12x = 24

x = 2

y = 8

Good luck.

Let the brother's age be x:

16years for Mary = 4x years for Brother

From equation: 4x = 16

x = 4

Therefore, the brother is 4 years old.

__Mary__ __ Brother__

16 4

After 4 years +__4 4__

20 8

After the next 4 years +__4 4__

24 12

24 is twice as old as 12; therefore for the sister to be twice as old as brother she will 24years when her brother is 12 years.

Or by calculation;

If 4 is the age for the brother, when the sister is 16, and y years will pass for the to be such that the sister is twice as old as the brother, then;

16 + y = 2(4 + y)

16 + y = 8 + 2y

16 - 8 = 2y - y

8 = y

Therefore, 8 years elapse before the sister is twice as old as the brother.

Sister will be: (16 + 8) = 24years

Brother will be: (4 + 8) = 12years

16years for Mary = 4x years for Brother

From equation: 4x = 16

x = 4

Therefore, the brother is 4 years old.

16 4

After 4 years +

20 8

After the next 4 years +

24 12

24 is twice as old as 12; therefore for the sister to be twice as old as brother she will 24years when her brother is 12 years.

Or by calculation;

If 4 is the age for the brother, when the sister is 16, and y years will pass for the to be such that the sister is twice as old as the brother, then;

16 + y = 2(4 + y)

16 + y = 8 + 2y

16 - 8 = 2y - y

8 = y

Therefore, 8 years elapse before the sister is twice as old as the brother.

Sister will be: (16 + 8) = 24years

Brother will be: (4 + 8) = 12years

This should start wit X=something and Y=something, sorry I'm not an human algebra calculator....

8x - 8 + 2y = 0

8X + 2Y = 8

y = -4x + 4

X = 0 por y-intercept

y=mx+b

Y = 8/2 or 4

Knock knock

Who's there?

4 who?

Why yall want me to do yall's homework 4?

Do the math on that! LOL

This is the process of how you would solve this.

-move the -3x over to the right hand side, so you have:

y = 5 + 3x

- since you know what x is, plug in the x which is 1:

y = 5 + 3(1)

- solve the equation

y = 5+3

y = 8, so the solution is 8.

Hi joanmae jmeh;

You can add these equations just like you would numbers

3x + 2y = 7

5x - 2y = 1

-----------------------

8x =8

x=1

Now plug x = 1 back into either equation and you can solve for y

Y = 2

When you add the 2 equations together the +2y and the -2y cancel

out

Hope this helps Loringh Please leave a rating for me Thks
