Parallelogram abcd has vertex coordinates a(0, 1), b(1, 3), c(4, 3), and d(3, 1). it is translated 1 unit to the right and 3 units down and then rotated 180° clockwise around the origin. what are the coordinates of a"?
choice a is correct answer.
y= mx+c is slope-intercept form for equation of line where m denotes slope and c denotes y-intercept.
slope is ratio of change in y to change in x.
slope= m = δy/δx
y-intercept is a point on graph where the value of x is zero.
given equation is :
y = 1/5x-6
hence,slope = m= 1/5 and y-intercept = c = -6
hence, choice a is your answer.
set up a ratio of neil armstrong's weight before over his after to the other persons weight before and after:
360 / 60 = 150 / x
360x = 150 * 60
360x = 9000
divide both sides by 360:
x = 9000 / 360
x = 25
a 150 pound person would weigh 25 pounds on the moon.
