1) Given equation is 4x + 2y = 24
i.e., 4x +2y -24 = 0...........(i)
given ordered pair is (4,4).
Now, replacing (x,y) by the point (4,4) in the expression 4x + 2y -24, we get,
4.(4) + 2.(4) - 24 =16 + 8 -24 = 24 -24 = 0
Therefore, the ordered pair (4,4) is a solution to the equation 4x + 2y = 24.
2) Let the equation of the line be y = mx + c ...........(i)
given slope of the line is 6.
Then the equation of the line becomes, y = 6x + c ............(ii)
Also given that the line passes through the point (2,3).
Therefore, 3 = 6.(2) + c
i.e., c = 3 - 12
i.e., c = -9
Hence, the equation of the line is, y = 6x -9.
3) Given equation is, x - 3y = -9 ..............(i)
Dividing both sides of (i) by -9 we get,
[x / (-9)] + [(-3y) / (-9)] = 1
i.e., [x / (-9)] + [y / 3] = 1
Therefore, the x-intercept for the equation is (-9,0) and the y-intercept for the equation is (0,3).
4) Let, the length of the base of the given triangle be x cm.
Here given, one side of the triangle is twice the length of the base and the other side is 4 cm longer than the base.
Then, the lengths of two other sides are 2x cm and (x + 4) cm respectively.
Now, the perimeter of the triangle is = [x + 2x + (x + 4)] cm
= 4x + 4 cm
By the given conditions, 4x + 4 > 36
i.e., 4x + 4 - 4 > 36 - 4
i.e., 4x > 32
i.e., (4x / 4) > (32 / 4)
i.e., x > 8
Hence, the length of the base must be greater than 8 cm.
