Ano ang x-intercept ng y = -3 (9-x) -7 + 9?

Sagot:

#color (violet) ("x-intercept" = a = 25/3, "y-intercept" = -25 #

Paliwanag:

#y = -3 (9-x) - 7 + 9 #

# "Paghadlang ng anyo ng isang linear equation ay" x / a + y / b = 1 #

#y = -27 + 3x - 7 + 9 #

#y = 3x - 25 #

# 3x / 25 - y / 25 = 1 #

#x / (25/3) + y / -25 = 1 #

graph {3x - 25 -10, 10, -5, 5}

#color (violet) ("x-intercept" = a = 25/3, "y-intercept" = -25 #

Sagot:

#color (brown) ("x-intercept" = 25/3 #

Paliwanag:

#y = -3 (9-x) - 7 + 9 #

#y = -27 + 3x - 7 + 9 #

#y = 3x - 25 #

Sa pamamagitan ng equating y -> 0, makakakuha tayo ng x-intercept

# 0 = 3x - 25 #

# 3x = 25 "o" x = 25/3 #

#color (brown) ("x-intercept" = 25/3 #
