Yes because multiple domain values can have the same range value, but not vice versa.
No.
Inside a circle, where the lines are drawn inside a 300 degrees angle will correspond with a 60 degrees angle, but the shaded parts are different. However, there is technically no such thing as a negative angle, so your answer is No.
hope this helps
A regular triangle is a triangle with 3 equal sides. A perimeter of a triangle with 3 sides = 3 x length = 3 (length). Since you know that the perimeter is also equal to 18x + 27, therefore,
3 (length) = 18 x + 27
length = (18x + 27) / 3 <-- divided both sides by 3
length = 6x + 9
An expression for the length of one of its sides is 6x + 9.
Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m = 
here, (xₐ, yₐ) = (2, 7)
and, 
⇒ m = 
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.
