Answer:
Machine B
Step-by-step explanation:
Since, Machine A covers
square feet in
hours,
Rate at which the Machine A is covering = 
= 
= 2.5 square feet per hour
Machine B covers
square feet in
hours,
Rate at which the Machine B is covering = 
= 
= 
= 3.33 square feet per hour
Therefore, Rate of Machine B is greater.
The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
Answer:
UHHHHHHH....…
Step-by-step explanation:
The first part of the set tells us that x is less than -5.
The second part tells us that x is greater than 5.
The intersection sign in the middle tells us to find "common" item in the first part and second part.
<u><em>Is there any number both greater than 5 and less than -5? No!</em></u>
So our solution doesn't exist and is the empty set.
ANSWER: The empty set
