I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
Answer:
vertex: (-1,25)
aos; -1
left x int: -6
right x int: 4
(not sure)
range is less than of equal to 25
Answer:
3 3/7
Step-by-step explanation:
7x+2v=48
2v. -2
-------
46
7x+46=48
-46. -46
---------------------
7x=2/7. x=2/7=1/7
x=1/7
Answer:
x = 14
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (14
)²
2x² = 392 ( divide both sides by 2 )
x² = 196 ( take the square root of both sides )
x =
= 14
Thus the congruent legs are 14 cm
