Answer:
Step-by-step explanation:
x = 1/4
y = -x = -1/4

Answer:
x=5, y=8
Step-by-step explanation:
x+y=13
2x-y=2
add these two equations
3x=15
therefore x=5
apply this value in x+y=13
5+y=13
then y=13-5 = 8
Answer: f=26
Step-by-step explanation: x^2+6x^2+12x+7/x= 26
Answer:
Step-by-step explanation:
a). Lines of symmetry of the circle given in the picture are,
x = 0
y = 0
y = -x
y = x
b). Since, a circle has infinite lines of symmetry (diameters) so the other lines of symmetry of the given circle will be all infinite numbers of the diameters.
c). Other symmetry this circle has a point symmetry.
(Looks the same when rotated by 180°).
6* 25 = 150 = (6*20= 120) + (6*5=30) Then Add 120+30= 150 so your answer is 5
