(i) false;
Let be N = { 0, 1 , 2}; x * y = x + y => a * a = 2a ∈ { 0, 2 , 4}, which is not a( just for a = 0);
(ii) true;
b * c = c * b => a * ( b * c ) = a * ( c * b ); (1)
but, a * ( c * b ) = ( c * b ) * a; (2)
(1) and (2) => <span>a * (b * c) = (c * b) * a.</span>
Answer:
True of corse you can obviously see that i think u are inteligent enogh to get it
Answer:
2.5
Step-by-step explanation:
Step-by-step explanation:
gradient/slope = 3
y-intercept
2x - 3y = 4
3y = 2x - 4
y = 2/3x - 4/3
so y-intercept is double -4/3 so... -4/3x2 = -8/3
the equation of the line is
y = 3x - 8/3 or 9x - 3y = 8
Answer:
The resulting equation is
x^2/4+16x^2/9=1
Step-by-step explanation:
The given equations are:
3y=12x eq(1)
x^2/4+y^2/9=1 eq(2)
We need to isolate variable y in equation 1
Divide both sides of the equation with 3
3y/3 = 12x/3
y = 4x
Now, substitute the value of y=4x in second equation
x^2/4+y^2/9=1
x^2/4 + (4x)^2/9 = 1
The resulting equation is
x^2/4+16x^2/9=1
