Answer:
Equation:
2(a+9) = a/2
Solve:
The umber is:
-12
Step-by-step explanation:
Equation:
2(a+9) = a/2
Solve:
2*a + 2*9 = a/2
2a + 18 = a/2
2a - a/2 = -18
4a/2 - a/2 = -18
3a/2 = -18
a = -18*2/3
a = -12
Check:
2(-12+9) = -12/2
2(-3) = -12/2 = -6
-3pi/2 is the same thing as pi/2
the terminal point on the unit circle for pi/2 is (0,1)
so that means the terminal point for -3pi/2 is also (0,1).
Answer:
Y2-y1/x2-x1
=2-(-6)/2-(-2)
=8/4
=2
Step-by-step explanation:
Given two points of a line to find the slope we use the formula; y2-y1/x2-x1 Hence the answer above.
