Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )
The should be 158 ways, because 9*8+8*7+6*5=158.
Answer: d) perpendicular bisectors of
Step-by-step explanation:
Answer:
about 18.85 cubic inches of ice cream can fit inside the cone
Step-by-step explanation:
To understand this, you will need to know the formula for a cone's volume which is
πr^2 times h/3
h being the height of the cone
to clarify the equation is pi (3.14) times the radius squared (which means you put it to the power of 2) and you multiply it by the height divided by 3.
Step by step:
π(1.5)^2 times 8/3
put it in a calculator and solve
round according to the problem
