Ответ:
x + y = 0
y = -x
Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
The answer is the first choice.
Ответ:
x+y = 0 y =(0-x)
3x-2y =10
3x-2(0-x)=10
3x-0 -2x=10
x=10
y=0-10 y = -10 FIRST ANSWER
Ответ:
This equation is not liner because the equation is not a straight line. At the point (0, 23) the equation bends.
