You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have

A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both  and
 and  are integers.
 are integers.
 
        
             
        
        
        
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).
<h3>What is the x-intercept of the line?</h3>
Given the function;
X-intercept occurs on the graph when y=0. Hence, to determine x-intercept, we substitute in 0 for y and solve for x.
3x - 5y = 7
3x - 5(0) = 7
3x - 0 = 7
3x = 7
x = 7/3
Hence, we have a point ( 7/3, 0 ).
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).

Answer:
6
Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6
