There is 2 midpoints on a line segment.
10%of30=3
3x4=12
A. 40%of 30=12 senior class members.
B. 60% of the class were not senior class members
We hates fractions
times everybody by 6x
6=x²-5x
minus 6 both sides
0=x²-5x-6
factor
what 2 numbers multiply toget -6 and add to get -5
-6 and 1
0=(x-6)(x+1)
set to zero
x-6=0
x=6
x+1=0
x=-1
x=6 or -1
You need to know:
Tangent function has range of <span>(-∞, ∞)
Sine function has range of [-1,1], which is the same as cosine function
So [-3,3] matches the 1st, [0,2] matches the 2nd, [-1,7] matches the 3rd, the 4th will be the rest </span>
