Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}

Answer:
525
Step-by-step explanation:
If the area of the map is 21 and the scale factor is 5:1, both of the dimensions of the flat park are multiplied by 5. If both dimensions are multiplied by 5, then the area is multiplied by (5*5)=25 times. 25*21=525. Hope this helps!
Step-by-step explanation:
cotx +2cotxsinx =0
cotx +2 
× sinx= 0
cotx +2 cosx= 0
+ 2cosx= 0
= 0
cosx +2 cosxsinx= 0
cosx ×(1+ 2sinx)= 0
Hence, either cosx= 0 that is x= 90° or 270°
or 1+ 2sinx = 0 that is sinx= 
i.e. x= 210° or 330°
As, 0° ≤x≤ 180° ∴ x= 90°
Answer:
A (3,0)
Step-by-step explanation:
The vertex is half way between the zeros
Add the zeros together and divide by 2
(2+4)/2 = 6/2 =3
The vertex is at x=3
