Answer:
m = 3/4; b = -3
Step-by-step explanation:
1) First, put the given equation into slope-intercept form. This is so we can identify its slope and y-intercept easily. Isolate y:
2) Lines that are in slope-intercept form are represented by the formula 
. The number in place of 
, or the coefficient of the x-term, represents the slope. The number in place of 
represents the y-intercept. So, the slope of 
is 
, and its y-intercept is -3.
This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:
8/-2=-32/8=128/-32=r=-4
The first term is -2
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
Since we know r and a for this problem already we can say:
a(n)=-2(-4)^(n-1)
Answer:
x = 0
Step-by-step explanation:
Expanding the left hand side we get
Taking 6 from left hand side to right hand side
Dividing both sides by 2
So, x = 0
The angles of a triangle always equal 180.
You do 180 - 80 - 45. X = 45.
