Given parameters:

First point  = (12, -5)

Second point  = (10, -4)

Unknown:

Slope of the line = ?

Slope is simply the vertical rise divided by the horizontal distance.

             Slope  = \frac{Rise }{horizontal distance}

Simply to find slope;

           Slope  = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

First point  = (12, -5), x₁  = 12 and y₁  = -5

Second point  = (10, -4), x₂  = 10 and y₂  = -4

Input the parameters:

       Slope  =  \frac{-4 -(-5)}{10 - 12}

                  = \frac{-4 + 5}{-2}

                  = - \frac{1}{2}

The slope of the line is -\frac{1}{2}

0.2(10-5c)=5c-16 halp
iogann1982 [59]

Answer:

c= 3

Step-by-step explanation:

0.2(10 -5c)= 5c -16

<em>Expand</em><em>:</em>

0.2(10) +0.2(-5c)= 5c -16

2 -c= 5c -16

<em>Bring</em><em> </em><em>all</em><em> </em><em>c</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

5c +c= 2 +16

<em>Simplify</em><em>:</em>

6c= 18

<em>Divide</em><em> </em><em>by</em><em> </em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

c= 18 ÷6

c= 3

Peaches come in large and small cylindrical cans. The larger can has a radiusand height that are both four times longer than the
Alik [6]

Answer:

D. 2058.24 in³

Step-by-step explanation:

Let r,h be the radius and height of smaller can and R,H be the radius and height of larger can

Then, R=4r  and H=4h

Volume of smaller can=32.16 in³

        ⇒                  πr²h=32.16 in³

Volume of larger can= πR²H

                                  = π(4r²)×4h

                                 = 64πr²h

                                 = 64×32.16 in³

                                =  2058.24 in³

Hence, correct option is:

D. 2058.24 in³
