Answer:
4
Step-by-step explanation:
This expression is a difference of squares.
(√3 + i)(√3 - i) = (√3)²-(i)², which is
3 - (-1)
= 3 + 1
= 4
Answer:
In which t is measured in decades.
Step-by-step explanation:
A linear function f(t) has the following format:
We are given two points of the function, so we can solve a system of equations to find the values for a and b.
61% of all adults in 1971 (t = 0)
This means that
So
51% in 2011 (t = 4)
This means that
So
So the linear function is:
In which t is measured in decades.
Answer:
m : the slope of the line.
( x, y ) : any point on the line.
( x1, y1 ) : a given point on the line.
Answer:x=1/24
Step-by-step explanation:
To find 9x(x+6)-(3x+1)^2=1
Open the brackets
9x^2+54x-(3x+1)(3x+1)=1
9x^2+54x-(9x^2+6x+1)=1
9x^2+54x-9x^2-6x-1=1
54x-6x-1=1
Collect like terms
48x=1+1
48x=2
Divide through by 48
x=2/48
x=1/24
