An isosceles trapezoid has a perimeter of 28.1 kilometers. Its shorter base measures 1 kilometer and its longer base measures 4.7 kilometers. The two remaining sides have the same length; what is that length?

.25

step-by-step explanation:

answer: it's upside down and i can't read it

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
