The answer is A right, scalene
Answer:
Step-by-step explanation:
Y = - 3x. Equation 1
x + y = - 4 equation 2
Putting value of y
x + (-3x) = - 4
x - 3x = - 4
-2x = - 4
x = - 4/-2 = 2
Putting value of x in the equation 1
Y = - 3(2)
Y = - 6
The value of given expression when x=-4 and y=4 is 1250.
The expression is missing in the question which is
.
We have to solve it for x= -4 and y = 4.
Now putting the value of x and y we get,



Hence the value of given expression when x=-4 and y=4 is 1250.
