Is y=(-2)* an exponential function? (*=x)

Select the lengths in centimeters that would form a right triangle

Using elimination, what is -4x+2y=-12 4x+8y=-24

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
