(3,3) and (6,5)
find slope
5-3/6-3=2-3=m so the answer is either a or d
now for point slope (3,3) was used so the correct equation would be
y-3=2/3(x-3) which is a!!
Last question of a really important test! I really need some help!
A hollow ball is made of rubber that is 1 centimeter thick. The ball has a radius of 5 centimeters at the outside surface.
What is the approximate volume of rubber used to make the ball?
Use 3.14 for pi.
255.4 cm³
Two deminsional or flat fuigure!
Answer:
you would divide 16500 by 500 and 1000
Step-by-step explanation:
so i got 12 and 16.5
Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
