Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of <em>'x>3 or x<-3' </em>which is more confusing.
Answer:
Kayla put 52,908 km on the truck.
Step-by-step explanation:
Subtract 27,544 km from 80,452 km to answer this question:
80,452 km
- 27,544 km
-------------------
52,908 km
Kayla put 52,908 km on the truck.
Answer:
y = sin(x+90)
Step-by-step explanation:
The shape of the graph shown is a y = cos x<em> </em>graph
Since that is not an option, we know that it must be translated somewhat
Sin x and cos x graphs are the exact same in shape, but differ by 90°
Y = sin (x+90) is the same as a Y = cos x graph, so Y = sin(x+90) is our answer
