Answer:
The range of the function is represented by ![Ran\{f(x)\} = (-15, 12]](https://tex.z-dn.net/?f=Ran%5C%7Bf%28x%29%5C%7D%20%3D%20%28-15%2C%2012%5D)
.
Step-by-step explanation:
Let be 
, for 
. As we notice that 
is an inyective function, that is, the inexistence of two or more domain element with the same image, with a monotone behavior, we can obtain the bounds of the range of the function by evaluating the expression:
Lower bound (
)
Upper bound (
)
The range of the function is represented by
16 + 36 = 52
unknown side = square root (52)
unknown side = 7.21
or
unknown side = 2 square root (13)
Answer:
There are 2 adults (2x5) and 5 children (5x2).
A reasonable estimate is like 8 or 9 or maybe even 10
hope this helps
Answer:
Small flags = 108
large flags= 47
Step-by-step explanation:
Step one:
given
let the number of small lag be x
and big flags be y
so
3.5x+6.5y= 683.5----------1
x+y=155------------------------2
Step two:
from eqn 2 x= 155-y
put x= 155-y in eqn 1
3.5(155-y)+6.5y= 683.5
542.5-3.5y+6.5y=683.5
collect like terms
3y=141
divide by 3
y= 141/3
y=47
Step three:
put y= 47 in eqn 2
x+47=155
x= 155-47
x=108
