Angle Z = Angle R = 35 degrees
Angle Y = 180-70-35 = 180-105 = 75
35 & 75 degrees
X = total miles run
4.6 + 0.78 + 3.4 = x
8.78 = x......so he ran a total of 8.78 miles
Because a function must pass the vertical line test , a function can have at most one y -intercept .
The y -intercept is often referred to with just the y -value.
