We substitute the point of intesection (1, 2) into the given options to see that only -x + 3 = 3x - 1 satisfies the graphs.
i.e. -x + 3 = -1 + 3 = 2
3x - 1 = 3(1) - 1 = 3 - 1 = 2.

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that two linear graphs intersect at (1,2). It means the solution of both lines is x=1 and y=2.

The equation which is satisfied by x=1 will be the required equation.

In option (1),

x+4=-2x-1

Substitute x=1.

(1)+4=-2(1)-1

5\neq -3

Option 1 is incorrect.

In option (2),

x+2=-3x+1

Substitute x=1.

(1)+2=-3(1)+1

3\neq -2

Option 2 is incorrect.

In option (3),

-x+3=3x-1

Substitute x=1.

-(1)+3=3(1)-1

2=2

Option 3 is correct.

In option (1),

x+3=2x-1

Substitute x=1.

(1)+3=2(1)-1

4\neq 1

Option 4 is incorrect.

Therefore the correct option is 3.

pychu [463]

Answer:

5 and a half

Step-by-step explanation:

Because you can fit 2 liters in each can, to find how many you would need, divide 11 by 2, this would give you 5 and a half, 5.5.

It could be that they want you to round up to six or round down to five, so do consider that.

Answer:

Option D - x = 3 3/5

Step-by-step explanation:

Lets make the left side into an improper fraction :

2 2/5 = 12/5

Now let's make both fraction into equivalent ones but with the same denominator :

2/3 = 10/15

12/5 = 36/15

Now we substitute the equivalent values back into the equation :

10/15 × x = 36/15

Now we multiply both sides by 15 to remove the denominators:

10 × x = 36

Now we divide both sides by 10 and simplify :

x = 36/10

x = 18/5

x = 3 3/5

So our answer will be Option D
