2y^2+ 2(9y^2 -8)
= 2y^2+ 18y^2 -16 (distributive property)
= 20y^2 -16
The final answer is 20y^2 -16~
Answer:
(2,-7)
Step-by-step explanation:
Use the midpoint formula! (Attached is a picture of it!)
1) Plug in the values:
(5-1)/2,(-6+-8)/2
2) Simplify:
4/2,-14/2
3) Solve:
(2,-7)
1. You have the following information:
Sinx=5/13
Cosx=12/13
2. By definiton, you have:
Tanx=(Senx)/(Cosx)
3. When you susbtitute Senx=5/13 and Cosx=12/13 into Tanx=(Senx)/(Cosx), you obtain:
Tanx=(Senx)/(Cosx)
Tanx=(5/13)/(12/13)
Tanx=(5)(13)/(13)(12)
Tanx=65/156
4. Therefore, the answer is;
Tanx=65/156
So if you want it to be 9 less than your number (x) then you would subtract nine.
So it would be:
x - 9.
So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).
