9m+2=3m-10
subtract 3m from both sides to get:
6m+2=-10
subtract 2 from both sides to get:
6m=-12
finally, divide by 6 on both sides to get what m equals:
m=-2

9m + 2 = 3m - 10

9m - 3m = -10 - 2

6m = - 12

m = -2

Find the slope of every line that is parallel to the line on the graph.​
melamori03 [73]

Answer:

-1/5

Step-by-step explanation:

What are parallel lines?

Lines that are parallel never touch. They can extend infinitely and they will still never touch. In order for this to happen the slope of the two lines must be the same. So if we want to find the slope of every line that is parallel to the line on the graph, we simply find the slope of the line of the graph.

Finding the slope

We can find the slope using the following formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Where the x and y values are derived from any given points on the line (x1,y1) and (x2,y2)

Here the given points are (-5,-1) and (0,-2)

So we have (x1,y1) = (-5,-1) meaning x1 = -5 and y1 = -1

We also have (x2,y2) = (0,-2) meaning x2 = 0 and y2 = -2

Now we plug these values into the formula

Recall formula : Slope=\frac{y_2-y_1}{x_2-x_1}

==> Plug in x1 = -5 , y1 = -1 , x2 = 0 and y2 = -2

Slope=\frac{-2-(-1)}{0-5}

==> simplify numerator and denominator

slope = \frac{1}{-5}

So the slope of the line is -1/5

This means the slope of any parallel line to that line would also have a slope of -1/5

Which of the following ratios is equivalent to 49:35?
Arte-miy333 [17]

The best way to find it is to reduce each ratio you work with to its
lowest terms,and see which ones are equal. To reduce a ratio to its
lowest terms, divide each number by their greatest common factor.

First, the one that you're trying to match:  <u>49:35</u> .
The greatest common factor of 49 and 35 is 7 .
Divide each number by 7 . . .  <em>7:5</em> . . . <u>that's</u> what you have to match.

<u>7:4</u>
Their greatest common factor is ' 1 '.
No help at all, and this one is not it.

<u>14:25</u>
Again, their greatest common factor is '1 '.
No help at all, and this one is not it.

<u>21:15</u>
Their greatest common factor is ' 3 '.
Divide both numbers by 3 . . . <em>7:5 </em>.
That's it !

kolbaska11 [484]
100% of Kerion's paper squares are:
 (100% / 100%) = 1
 Half of the squares of your paper are colored blue:
 (1) / (2) = 1/2
 Of the blue squares, 1/3 of them will also have stripes:
 (1/2) * (1/3) = 1/6
 answer
 A fraction of (1/6) squares will be blue with strips
