Answer:
Step-by-step explanation:
so why this kind of problem is so confusing is b/c it's 2 problems in one
if you were to expand this it look like this
10 ≤2x
and
2x ≤x+9
This is really saying.. that x has a range.. and that the 1st equations is the lower stop point, and that the 2nd equations is the upper stop point
once it's taken apart.. I bet you can solve it pretty quickly.
5≤x
and
x ≤9
then just put it back together in that confusing .. yet handy way to write it,
5≤x≤9
Answer:
Sin(E) = 
Step-by-step explanation:
The full question is as follows :
To find - In the accompanying diagram, what is sin E?
Proof -
We know that,
Sin(theta) = (opposite side) / (hypotenuse)
From the diagram, we can see that,
Base = 3
Perpendicular = 5
Hypotenuse = 5
So,
For angle E,
Opposite side = 4
Hypotenuse = 4
∴ we get
Sin(E) =
No they are not equivalent to one another because in order to get from 6to 42 you have to multiply by 7 but to get from 11to 88you have to multiply by 8 . In order for to ratio to equivalent they must have the same factors
