Step-by-step explanation:
y=6+4x, as equation (iii)
=> -5x-(6+4x)=21
=> -5x-6-4x=21
=> -5x-4x-6=21
=> -9x-6=21
=> -9x=21+6
=> -9x=27
x= -3, by dividing both sides by -9
So, by inserting x in the first equation,
=> -4(-3)+y=6
=> 12+y=6
=> y=6-12
=> y= -6.
Therefore, x= -3 and y= -6
Answer is (d) P, Q , R
Any triangle has 3 vertices , after which its name is justified
Answer:29
Step-by-step explanation:
Opposite angles in a quadrilateral (the trapezium inside the circle) must add up to 180, so 180-92 = 88.
So DAB = 88
Angles on a straight line add up to 180, so to find t, you have to 180 - 88 - 63 = 29
So t is 29.
Hope that helps!
If i'm understanding this question correctly, i believe that it's 2.
2*9=6*3
