Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3
The answer is D
Hope this helps :)

Answer:
400%
Step-by-step explanation:
Divide 6 inches by 1.5:
6/1.5 = 4
6 is four times 1.5
If 1.5 is considered 100%, 4 times 1.5 is 400%
The area of rectangle = 24 × 8 = 192 cm^2 ;
The area of triangle = ( 16 × h ) / 2 = 8 × h ; where h = the height of the triangle ;
the rectangle and the triangle have equal areas;192 = 8 × h ;
h = 192 ÷ 8 ;
h = 24 cm ;
