Supplementary angles mean they equal 180 degrees which means any two angles that equal a line. so that would be:
<1 and <3
<1 and <4
<2 and <3
and <2 and <4
as all of these angles (in their respective pairs) create a single line which is equivalent to 180 degrees
at most is either that number or less
so x<=72 would be the inequality
A quadratic graph. It makes an upside down U shape
Answer:
<em>f of x equals negative one third x plus 5</em>
Step-by-step explanation:
<u>Question 1
</u>
We know the line contains the point (a,b)=(0,1) and has a slope m=0
We can find the equation of a line knowing both parameters by using
y-b=m(x-a)
y-1=0(x-0)
This is the required equation of the line
y=1
<u>Question 2
</u>
The student is running a 5-Km race. Les's set x as the time in minutes. 3 minutes are needed to complete one Kilometer, so every single minute will be enough to run 1/3 Km. Every x minutes, the distance will be

Since the runner needs to complete 5 Km in total, the distance still to complete will be


This is the required function. It can be written as
"f of x equals negative one third x plus 5"
