Answer:
Step-by-step explanation:
Corresponding angles equal 180 degrees when added
6x + 3x = 180
9x = 180
x = 20
angle CBD is 60 and angle GFH is 120
3(20) = 60
6(20) = 120
Answer:
15.7
Step-by-step explanation:
The equation for finding the circumference of a circle is
2 x pi x r(radius). Radius is half the diameter.
5/2=2.5
2 x 3.14 x 2.5
=15.7
There will only be one solution to this problem.
220 = 2x - 12x
Combine like terms on the right side of the equation:
220 = - 10x
Divide both sides by - 10 to isolate the variable x.
220 / - 10 = x
-22 = x, one solution.
Answer:
Step-by-step explanation:
Pick any 2 points and then plug it in to the formula for slope
y2-y1
_____. (Rise over run)
x2-x1
Pick 2 ordered pairs (x,y) and then plug in the respective values for x and y
Once plugged in, subtract for the top and bottom values
Then divide the values
The answer is the slope
Answer:
for n=2, f(2)=f(1)*(-1/2) we know that f(1)= -16 so put it
f(2)=(-16)*(-1/2)=8
then put n=3 so f(3)=f(2)*(-1/2)
f(3)=8*(-1/2)= -4
