Answer:
( f + g ) (x) = 
g(x) - f(x) = 
Step-by-step explanation:
- f(x) = 4 x - 4 and g(x) =
( f + g ) (x) = f(x) + g(x)
= 
= 
2. g(x) = 
and f(x) = 2 x + 5
g(x) - f(x) = 
= 
=
Answer:
Yes, it is linear
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
You cannot conclude that ΔGHI is congruent to ΔKJI, because although you can see/interpret that there all the angles are congruent with one another, like with vertical angles (∠GIH and ∠KIJ) and alternate interior angles (∠H and ∠J, ∠G and ∠K), we don't know the side lengths.
All the angles could be congruent, but the sides might be different. For example, ΔGHI might be a bigger triangle than ΔKJI, which could make them similar to one another, but not congruent.
For something to be congruent to another, everything must be exactly the same.
Answer:
x=30° y=110°
Step-by-step explanation:
80+70=150
180-150=30° 》》》》 angles in a triangle add up to 180°
x=30° opposite angles are equal
180-140=40° angles on a straight line add up to 180°
30+ 40=70
180-70=110°
y=110°
N and n+2 because if n=1 then you do 1+2 and that equals 3. So then you have 1,3
