Answer:

1\frac{5}{7}

Step-by-step explanation:

4\frac{3}{7} -2\frac{5}{7}

Step 1. Simplify left side 4*7+3 , Right Side 2*7+5

=\frac{31}{7} -\frac{19}{7} = \frac{12}{7}

Step 2. Re-write 12/7 as mixed number

\frac{12}{7} = 1\frac{5}{7}

What is the slope of line<br> 4x+6y=24
Varvara68 [4.7K]
Y=mx+b
m is the slope
you need to get y on one side and all other numbers on the other
so here's the easiest way to do it:
just kinda take 4x (which is a positive number) and move it to the other side and change the sign. so then it turns into 6y=-4x+24 and then you divide both sides by 6 so then you get y=-4/6x+4 (4 over 6 like a fraction)
-4/6 is the slope

Calculate the slope between the coordinates (-2,3) and (2,-1) using the slope formula.
matrenka [14]

Answer:

slope = -1

Step-by-step explanation:

First, you need to know the slope formula: <u>y2 - y1</u>

                                                                       x2 - x1

Now recognize the first point (-2,3) as (x1,y1) and the second point (2,-1) as (x2,y2)

Now that you have done that, plug in the numbers into the slope equation.

Which should look like this:      <u>-1 - 3</u>

                                                   2 - -2

Now that your equation looks like this, recognize the denominator, we should know that a negative plus a negative equals a positive. So instead of subtracting the denominator of the equation, we are going to add the two numbers together, because x1 is negative. Now solve, you should get the answer -1.

                       <u>-1 - 3</u>                        <u>-4</u>    = -1

                       2 + 2                        4

V=mile per hour

V=\frac{7}{8}/ \frac{1}{4}

V=\frac{7}{8}*\frac{4}{1}

V=\frac{7}{8}*4

V=3.5
