Given: K=2∙33∙11∙172and M=3∙11∙173<br><br> Evaluate 18·M÷K.
gayaneshka [121]

Answer:

  1557/1892

Step-by-step explanation:

Your calculator can do this:

\dfrac{18M}{K}=\dfrac{18\cdot 3\cdot 11\cdot 173}{2\cdot 33\cdot 11\cdot 172}=\dfrac{18\cdot 173}{2\cdot 11\cdot 172}\\\\=\dfrac{1557}{1892}

Write the slope-intercept form of the line through the points (4,-5) and (2, -1).
Leokris [45]
Slope intercept form is y=mx+b
to solve for m (slope) you must first subtract y2-y1 and x2-x1 then divide your answers

-1 - -5 = 4 (y)
2 - 4 = -2 (x)
4/-2 = -2

so your slope is -2

next plug in your slope and the point you choose

-1 = -2(2) + b
or
-5 = -2(5) +b
