First, you simplify 12x=3y+7. Subrtact 7 from both side, get 12x-7=3y. Divide 3 from both sides, get y=4x-(7/3). Your 2 equations are y=4x-1 and y=4x-7/3. The 2 lines are parallel, since they have the same slope but different b's.

Answer:

Neither is the answer.

Step-by-step explanation:

If a line y = m₁x + c₁ and y = m₂x + c₂ are perpendicular to each other then m₁ × m₂ = -1

If both the lines are parallel to each other then m₁ = m₂

Now two lines have been given as

y = 4x - 1 ----------(1)

12x = 3y + 7

3y = -12x + 7

y = -4x + \frac{7}{3}------(2)

Now from equation (1) and equation (2),

m₁ = 4 and m₂ = -4

Since m₁ ≠ m₂

Therefore, these lines are not parallel

m₁ × m₂ = 4 × (-4) = -16

Therefore, both the lines are neither parallel nor perpendicular.

2 of the necklaces are blue.

Because she has 8 necklaces in total and 1/4 of those 8 are blue, you would divide 8 by 4.

1/4 of 8 is equal to 2

2y-8+4y what is equal to this please help thanks
Nitella [24]

Answer:

6y - 8

Or

2(3y - 4)

Step-by-step explanation:

The given expresion is 2y-8+4y.

We want to find an expression that is equal to 2y-8+4y.

We need to group like terms to obtain:

2y + 4y - 8

We can now combine the like terms to get:

2y + 4y - 8

6y - 8

We can factor 2 to obtain:

2(3y - 4)
