AB = BC
2x + 7 = 23
2x = 16
x =8

AD = 4x + 1 = 4(8) + 1 =33
but
AD = DC
so
DC = 33


answer
D. 33 units

vfiekz [6]

Answer: y - 5 = -5/6 (x - 18)

Step-by-step explanation:

The point-slope form of a linear equation is written using the slope of the line and one point in the line. From part A, the slope of the line representing this situation is m = -5/6.

Since x represents the number of 10-student groups and y represents the number of 12-student groups, the combination of 18 groups of 10 students and 5 groups of 12 students is represented by the point (18,5).
