## what is sum of x/x+y and y/x+y?​

Ask: what is sum of x/x+y and y/x+y?​

1

Step-by-step explanation:

since they have the same denominator, we can simply add their numerators

x/(x+y) + y/(x+y) = (x+y)/(x+y)

cancel the numerators and denominators

(x+y)/(x+y) = 1

1

Step-by-step explanation:

since both terms are in proper fraction or samr denominator. you will just have to add the numerator and then copy the denominator.

x/(x+y) + y/(x+y) = (x+y)/(x+y)

to simplify, when we divide x+y to x+y

## What is the relation of the x² – y²and (x

Ask: What is the relation of the x² – y²and (x + y) (x – y)?​

Step-by-step explanation:

– x^2 y^2 + x^2 + y^4 thats the answer

## y= 3x-4if y is 8, what is x?if x is

if y is 8, what is x?
if x is -2, what is y?
if y is 0, what is x?

Step-by-step explanation:

y= 3x-4

if y is 8, what is x?

Substitute:

8=3x-4

8+4=3x

12/3=3x/3

### 4=x

if x is -2, what is y?

substitute:

y=3(-2)-4

y=-6-4

### y= -10

if y is 0, what is x?

substitute:

0=3x-4

4/3=3x/3

## 1. What is y when x = 9?2. What is

Ask: 1. What is y when x = 9?
2. What is y when x= 3?
3. What is y when x=15?
4. What is x when y=3?
5. What is x when y=30?​

1 .

Choice (B) is correct.

Since the variables x and y are directly proportional, they are related by an equation y=kx, where k is a constant. It is given that y = 2 when x = 3, and so 2 = k(3), which gives k = Therefore, y = x and so when x = 9, the value of y is y = (9) = 6.

2.

When

x=3

y=k×3

y=5×3=15

## answer the question then graph: 1. x – 2y =

1. x – 2y = 4 2x + y = 1 if x= 0. what is the value of y? If y= 0. what is the value of x? 0

2. Y = X + 7 Y = X – 4 if x= 0. what is the value of y? If y= 0. what is the value of x?

3. 2x + y = 3 4x + 2y = 6 if x= 0. what is the value of y? If y= 0. what is the value of x?​

1. x = 4

x = 1/2

y= 2

y = 1

2. x = -7

x=4

y=7

y=-4

3. x=2/3

x=3/2

y=3

y= 3

Step-by-step explanation:

1. x -2(0)=4. 0 – 2y=4

x-0=4. -2y=4-0

x=0+4. -2y=4

x=4. y=-2

2x + (0) = 1. 2(0) + y = 1

2x = 1-0. 0 + y = 1

2x=1. y = 1-0

x= 1/2. y = 1

## 2x + 4y = 4 If x = -2, what

Ask: 2x + 4y = 4
If x = -2, what is y?

3x – y = -1
If x = 0, what is y?

x + y = -2
If x = 2, what is y?

2x – y = 4
If x = 1, what is y?

1. y=8

2. y=1

3. y=4

4. y= -2 (not sure)

1. 2 (-2) + 4y = 4
-4 + 4y = 4
4y = 4 + 4
4y = 8 (divide both side to 4)
y = 2

2. 3 (0) – y = -1
0 – y = -1
y = 1

3. 2 + y = -2
y = -2 – 2
y = -4

4. 2(1) – y = 4
-y = 4-2
-y = 2
y = -2

## 2x+y=4if x is 0, what is y?if y is 2,

if x is 0, what is y?

if y is 2, what is zero?

If x is -2, what is y?​

2x+y=4

if x is 0

2(0)+y=4

0+y=4

y=4

if y is 2

2x+22=42

2x=2

2

x=1

if x is 2

2(2)+y=4

4+y=4

4+4+y=4+4

y=8
