4x=2/3(x - 2)
4x=2/3x - 4/3
4x - 2/3x=4/3
4x - 2/3x=-4/3
10/3x=-4/3
x=-4/3 * 3/10

x=-12/30
x=- 2/5
hope this helps

2/3(x - 2) = 4x....distribute thru the parenthesis
2/3x - 4/3 = 4x...subtract 2/3x from both sides
-4/3 = 4x - 2/3x
-4/3 = 12/3x - 2/3x
-4/3 = 10/3x
-4/3 * 3/10 = x
-12/30 = x
- 2/5 = x <==

1. Determine whether the graphs of the given equation are Parallel, perpendicular, or neither.

Juliette [100K]

1. A. parallel, because when you get y by itself it is y=-2x+7, the two equations have the same slope which means they are parallel.

2. B. sometimes, in order for two lines to be parallel they have to have the same slope so, it is possible that two lines say with a slope of 3, those would be parallel BUT it doesn't always have to have a positive slope for it to be parallel like in question 1.

3. C. never, If they have the same slope they are parallel despite whatever the y-intercept is.

Line Equation from Two Points

Verdich [7]

Hi!

We can use point-slope form to solve this.

$y-y_{1} =m(x -x_{1})$

$y_{1}$ and $x_{1}$ will be from one of the points.

First, we have to find $m$ , the slope. We can use the slope equation to get this.

$\frac{y_{1} -y_{2} }{x_{1} -x_{2} }$

Plug in your points:

$\frac{4-0}{8-(-8)} =\frac{4-0}{8+8} =\frac{4}{16} =\frac{1}{4}$

Your slope is $\frac{1}{4}$

Now plug points and slope into point-slope equation. We will use (8, 4).

$y-4=\frac{1}{4} (x-8)$

Now, if you want to get it into y = mx + b form, you have to solve for y:

$y-4=\frac{1}{4} (x-8)$

$y-4=\frac{1}{4} x-2$

$y=\frac{1}{4} +2$

Your equation is $y=\frac{1}{4} +2$

The table and the graph each show a different relationship between the same two variables, x and y:

SCORPION-xisa [38]

When x=2 y = 110 which means when when x=1 y = 55
the graph would be 11*55 or 605
The table would be 280/4= 70 70*11=770
Which means the difference is 770-605=165

165 is ur answer
