M∠ADB + m∠BDC = m∠ADC   [<span>angle addition postulate]

x + x + 10 = 60 
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25

a
m</span>∠ADB = x = 25°

b 
m∠BDC = x + 10 = 25 + 10 = 35°

Complete the following steps for this equation.
Troyanec [42]
1. <span>4x – 20 = 5y

so 5y = </span><span>4x – 20

divide both sides by 5

y = (4/5)x - 4


2. x-intercept is at y=0

so (4/5)x - 4 = 0

x = 5

so it is (5,0)


3. y-intercept is at x=0, y = 0 - 4 = -4

so it is (0,-4)
