Answer:
[-1, ∞ )
Step-by-step explanation:
The use of parentheses is essential here. I am assuming that you meant:
y=√(x-5) - 1
Note that √(x-5) has the range [0, ∞ ). The domain is [5, ∞ ).
Thus, y=√(x-5) - 1 has the range [-1, ∞ )
Answer:
Step-by-step explanation:
56y^2/9-30y+25
Answer:
your answer is 14/15.
you get that by deciding on the least common multiple, which is 15, then you adjust the fractions so you can add them together.
Answer:
The value of a = 14
Step-by-step explanation:
Given
(x₁, y₁) = (2, 4)
(x₂, y₂) = (6, a)
(x₃, y₃) = (-1, 1)
A = 9 sq.units
Area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃) is:

substituting the values (x₁, y₁) = (2, 4), (x₂, y₂) = (6, a), (x₃, y₃) = (-1, 1), A = 9 in th formula


Multiply both sides by 2

simplify

As the area is always positive.
so


Add 18 to both sides

simplify



Divide both sides by 3


Thus, the value of a = 14
All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
