odpoveď:

X-zachytiť **#=3/8#

# y = 2 / 3x-1 / 4to #. Pre X-zachytenie vložte y = 0.

#:. 0 = 2/3 x-1/4 => (2x) / 3 = 1/4 => 2x = 3/4 => x = 3/8 #

vysvetlenie:

Ak riadok # Ax + o + c = 0 #, potom X-intercept =# - (c) / a #

# Y = 2/3 x-1/4 => 12y = 8x-3 => 8x-12y-3 = 0 #

Tu,# A = 8, b = -12, c = -3 #

#:.#X-intercept = **#-(-3)/8=3/8#
