Janine’s error is that she incorrectly counted the spaces that point C has shifted. Focusing on point C like Janine did, to get to point C’ you would need to shift 3 units to the left and 5 units down. This would make the new translation rule (x-3, y-5) to get from triangle ABC to triangle A’B’C’.
Answer: ( x - 1 ) ( x + 4 ) = 0.
Step-by-step explanation:
Let's see 1. To make this equal to zero you write x - 1 where you substitute 1 in x.
Again let's see -4. To make it equal to zero, you write x + 4 where you substitute -4 in x.
So, this results in ( x - 1 ) ( x + 4 ) = 0
Answer:
See explanation
Step-by-step explanation:
If segment AB is tangent to the smaller circle, than AB⊥OR. Consider two right triangles AOR and BOR. In these triangles:
- OR is common leg;
- AO=OB as radii of larger circle;
- ∠ARO=∠BRO, because AB⊥OR.
By HL theorem, ttriangles AOR and BOR are congruent. This gives you that AR=RB.
Answer: millas
Step-by-step explanation: solo en una milla hay 1.609 kilómetros so 20 millas es mayor que 20 kilómetros.
Lo siento si está no es la respuesta que busca.
Answer:
D. n+n+2+n+4+6= -72; n= -21; n+2= -19; n+4= -17; n+6= -15
There are 2 below and 2 above it.
-15, -17, -19, -21
Step-by-step explanation:
the sum of four consecutive odd integers is -72. write an equation to model this situation, and find the values of the four integers
.
n + n+2 + n+4 + n+6 = -72
4n + 12 = -72
or
-72/4 = -18, the center
