Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7

union of the two parts of y: 1≤y<7
[1,7) is the answer.

How to write a paragraph proof? Given: ∠T and ∠V are right angles TW║VU.<br> Prove: ΔTUW≅ΔVWU
mafiozo [28]

Note: The missing diagram is attached below for a reference.

Answer:

  • Δ TUW ≅ ΔVWU by AAS case.

Step-by-step explanation:

Given:

  • ∠T and ∠V are right angles.
  • TW║ VU

To Prove:

  • Δ TUW ≅ ΔVWU

As

∠ T ≅ ∠ V ≅ 90^{0} (Given)

Side  UW ≅

TW║ UV

and UW is a transverse

So,

∠ TWU ≅ ∠ WUV \left[alternate\:\:interior\:\:angles\right]

As\:Angle\:=\:Angle\:=\:side\:are\:equal

Thus,

  • Δ TUW ≅ ΔVWU

Keywords: proof, paragraph, logic, reason

Need Help With Math. One Question
alina1380 [7]

Answer: 2 < x < 16

The triangle inequality theorem says that if we have a triangle with sides a,b,c then

b-a < c < b+a

with b being longer than 'a'

In this case, a = 7 and b = 9 and c = x

so we have

b-a < c < b+a

9-7 < c < 9+7 .... replace a with 7, replace b with 9

2 < c < 16

2 < x < 16 .... replace c with x

So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.

I need help please!!!

Answer:

D

Step-by-step explanation:

A translation 4 units to the right and 6 units down means that all of the x values increase by 4 and all of the y values decrease by 6.

Adding 4 to all of the x values and subtracting 6 from all of the y values gives us the coordinates:

A' (-3, 0), B' (8, 3), C' (2, -9)
