Answer:

D, the lines coincide.

Step-by-step explanation:

isolate the y so theres no 2y, only y:

2y = 8 - 2x (divide both sides by 2)

y = 4 - x

The lines are the same line, so while they are plural, they also coincide, as one lies on top of the other.

Hope this helps :) Brainliest??

Solve for x: 2/7(x-2)=4x

lawyer [7]

Answer:

$x = - \frac{2}{13}$

Step-by-step explanation:

Simplify to:

$\frac{2(x - 2)}{7}$

Multiply both sides by 7

2(x-2)=28x

Divide both sides by 2

x-2=14x

Subtract x from both sides

2=14x-x

Simplify 14x-x to 13x

2=13x

Divide both sides by 13

$- \frac{2}{13} = x$

Answer:

$x = - \frac{ 2}{13}$

Here is a pattern of dots.

EleoNora [17]

The dots in the patterns are illustrations of a sequence or progression

The number of dots in step 10 is 84
The number of dots in step n is (n -1)^2+ 3

<h3>The number of dots in step 10</h3>

From the pattern, we have:

Step 0 = 3 dots
Step 1 = 4 dots
Step 2 = 7 dots
Step 3 = 12 dots

So, we have the following pattern

$T_n = (n -1)^2+ 3$

When n = 10, we have:

$T_{10} = (10 -1)^2+ 3$

T10 = 84

This means that, there will be 84 dots in step 10 and there will be (n -1)^2+ 3 dots in step n
