Set up the proportion line up minutes with minutes and miles with miles so it would be x over 60 36 over 45 and u get 48
Answer:
x=-3/2
Step-by-step explanation:
=>ln(3x-3)=In(x-6)
=>3x-3=x-6 (since the bases of the logarithms are same)
=>2x=-6+3
=>2x=-3
=>x=-3/2
a straight line is 180 degrees so we can find C by subtracting 140 from 180
180-140 = 40 degrees
all 3 inside angles need to equal 180 so now we have
180 = 40 + (2x) + (x+2)
180 = 40 +3x +2
180=42+3x
138=3x
x= 138/3 = 46
check : 2x= 2*46 = 92
x+2 = 46+2 = 48
92 +48 +40 = 180
so x = 46 degrees
so angle B = 2x46 = 92 degrees
Y=mx+b
m = slope
y = -3x/4 +b
4 = -3*0/4 + b
4 = b
y -3x/4 + 4
