Answer:
B polynomial; binomial
Step-by-step explanation:
Yes, it is a polynomial, as it has two terms therefore it is a binomial.
Answer:
![b\leq 12](https://tex.z-dn.net/?f=b%5Cleq%2012)
Step-by-step explanation:
Formula of a rectangle:
![a=h*w](https://tex.z-dn.net/?f=a%3Dh%2Aw)
a = area
h = height
w = width (or base length)
Replace the variables with the numbers given:
![48=4*b](https://tex.z-dn.net/?f=48%3D4%2Ab)
Divide both sides by 4:
b = 12
Since 48 is the max, the number can only be equal to or lower than 12:
![b\leq 12](https://tex.z-dn.net/?f=b%5Cleq%2012)
I believe the second choice is the correct answer. :)
Answer:
![\frac{11}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B2%7D)
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x =
(x) , thus
(x) = ![\frac{x+1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B1%7D%7B2%7D)
Evaluate g(3) and substitute the value obtained into
(x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) =
= ![\frac{11}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B2%7D)
Answer:
x=2
Step-by-step explanation:
=>30x = 30+30
=>30x = 60
=>x= 60/30
=>x=2
