must be the equation
y > x+1
because the slope is 1 and is 1 abve the origin and a dotted line
I’m x is degrees since is downs

Answer:
127 hamburgers
Step-by-step explanation:
let c = # of cheeseburgers
let h = # of hamburgers
c = 2h (The number of cheeseburgers sold was two times the number
of hamburgers sold.)
h + c = 381 (combined total)
h + 2h = 381
3h = 381
h = 127
Answer:
The amplitude is 
Step-by-step explanation:
Let f(x) be a sinusoid function that has the following format:

Then b is the amplitude of the function
h is the vertical displacement of the wave
s is the phase angle
is the period.
In this problem 
Then 
Therefore the amplitude of the function is 
The amplitude is a measure of the vertical size of the sinx wave
