Answer: i think it is 2/7
Step-by-step explanation:
Answer:
-3x-16
Step-by-step explanation:
(2x-6)-(5x+10)
2x-6-5x-10
2x-5x-6-10
-3x-6-10
-3x-16
The final answer is (2,1).
Step 1: Solve for either x or y in one of the two equations.
x + 3y = 5
- 3y - 3y
----------------------
x = -3y + 5
Step 2: Substitute the expression you got for x into the opposite equation.
-3y + 5 - 3y = -1
-6y + 5 = -1
- 5 - 5
--------------------
-6y = -6
------ -----
-6 6
y = 1
Step 3: Plug in the solution you got for y into either of the 2 equations.
x + 3(1) = 5
x + 3 = 5
- 3 - 3
---------------
x = 2
Answer:
<u>We observe that this is a GP with:</u>
- the first term t₁ = 5
- common ratio r = -2
<u>The nth term is:</u>
we know that
2pi radians (full circle) has an area of-----------------> 100pi
then
(2pi/5) radians----------------------------> X
X=(2pi/5)*100pi/2pi---------> 20pi units²
the answer is
20pi units²
