Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
If the function 1 in graph is a horizontal line y=3 then it has zero rate of change because y is same along the x axis.
Function 2 has rate of change of 2.
Y=mx+c m represents rate of change
