(f∘g)(x) = f(g(x)) = f(x +2)
= 2(x +2) -1
= 2x +3 . . . . . selection D
Answer:
ans: ii) 87° and iii) 60°
Step-by-step explanation:
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
Jon=x-2 jor=x
2(x-2)=x+6
2x-4=x+6
combine like terms
x=10 Jordan's age
x-2 or 10-2 =8 Jonathan's age
13-10= 3 years apart
when aylon was 3 Karina was 6
2×3 =6
this was 7 years ago(answer)
10-3=7
13-6=7
48-36=12 years apart
when kd was 6 and md 18
3×6=18
30 years ago
36-6=30
48-18=30
Answer: 6
