Answer:

d= -2

Step-by-step explanation:

1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :   2*d+4-(10+5*d)=0

2. Pull out like factors :  -3d - 6  =   -3 • (d + 2)

3.Solve :    -3   =  0

4. the equation has no soluton because A a non-zero constant never equals zero.

5.  then Solve  :    d+2 = 0

6. Subtract  2  from both sides of the equation :  

                 <u>d = -2</u>

Find the slope of the line that passes through the pair of points
love history [14]

Answer:

\frac{5,805}{2812}

Step-by-step explanation:

To find the slope from two points you can use the following formula:

m = \frac{y -y_{1} }{x -x_{1} }

Now substitute the two sets of points (\frac{7}{20}, \frac{5}{19} ) and (\frac{5}{9}, \frac{11}{16})

Substitute the values like this:

y = \frac{5}{19}, y_{1} = \frac{11}{16}, x = \frac{7}{20} and x_{1} =\frac{5}{9}

Now you will need to simplify the following expression:

m = \frac{\frac{5}{19} -\frac{11}{16} }{\frac{7}{20}-\frac{5}{9} }

Make sure that denominators are the same before substracting:

m = \frac{\frac{-129}{304} }{\frac{-37}{180} }

when you divide with a fractional number you only need to flip the second fraction over (find its reciprocal). Then just multiply:

m = (\frac{-129}{304} })({\frac{-180}{37} } ) = \frac{5805}{2812}
