Use slopes to determine whether the lines AB and CD are parallel, perpendicular, or neither. SHOW WORK A(-10, 8) and B (-9,4).
C (-5, 12) and D (2,9).

Neither

Step-by-step explanation:

Slope for AB is -4

Slope for CD is -3/7

in order to find the slope use this formula attached

AB -9-(-10) / 4-8 = -4         your y2 is 4 your y1 is 8 / x2 is -9 x1 is -10

CD 9-12 / 2-(-5)                 your y2 is 9 your y1 is 12 / x2 is 2  x1 is -5

The lines will be neither

Line A is Purple dot

Line B is Blue dot

Line C is Red dot

Line D is Green dot

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
