Area of a circle is pi x r ^2
R = diameter/2
R = 1.8/2 = 0.9
Area = 3.142 x 0.9^2
Area = 2.5 square cm.
Multiply both sides by 6
(b-4)/6*6= b-4
b/2*6= 3b
Rewrite the equation
b-4= 3b
Subtract b from both sides
-4=2b
Divide both sides by 2
-2=b
Final answer: b=-2
Answer:
14th term
Step-by-step explanation:
first you have to find the triangle, then you can move to the actual question.
x+30+80 = 180
x+110 = 180
x+110 - 110 = 180-110
x =70
now you can go to the actual question.
y + 70 = 180
y+70- 70 = 180-70
y = 110
there is your answer. hope this is helpful
Answer:
y=5x+42
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-(-3))/(-7-(-9))
m=(7+3)/(-7+9)
m=10/2
m=5
y-y1=m(x-x1)
y-(-3)=5(x-(-9))
y+3=5(x+9)
y=5x+45-3
y=5x+42
