Answer:

( f + g ) (x) = 2 x^{2}  + x - 4

g(x) - f(x) = x^{2}  - 2 x - 4

Step-by-step explanation:

  1. f(x) = 4 x - 4 and g(x) = 2 x^{2} - 3 x

( f + g ) (x) = f(x) + g(x)

                = 4 x - 4 + 2  x^{2}  - 2 x

                = 2 x^{2} + x -4

   2.  g(x) = x^{2}  + 1 and f(x) = 2 x + 5

g(x) - f(x) = x^{2}  + 1 - (2 x + 5)

              = x^{2}  + 1 - 2 x - 5

              = x^{2}  - 2 x - 4

In the figure to the right, can you conclude that triangle GHI is congruent to triangle KJI? Justify your reasoning.
inessss [21]

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.

Find the value of x and y..​
Tomtit [17]

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°
