#9 the sum of two angles is 90 degrees, creating a right angle.
#10 the sum of the two angles is 180 because the form a supplementary angle
Answer:
Step-by-step explanation:
5x + 2 = 4x - 9
Collecting like terms
5x - 4x = -9 - 2
x = -11
The domain of the function is x ≤ 6.88
The domain of the function is y ≤ 20
<h3>Domain and Range</h3>
- These are input and output values for which the function exists
Given the function of x expressed as:
y = 3.5x + 2.8
The domain occurs at the point where 3.5x + 2.8 ≤ 20
3.5x ≤ 20 - 2.8
3.5x ≤ 17.2
x ≤ 6.88 - Domain
This given the domain of the function.
The range of the function is the point where y ≤ 20
