Answer:
x= -12 and y=8
Step-by-step explanation:
Let's solve your system by substitution.
−x−y=4;x+2y=4
Step: Solve−x−y=4for x:
−x−y=4
−x−y+y=4+y(Add y to both sides)
−x=y+4
−x
−1
=
y+4
−1
(Divide both sides by -1)
x=−y−4
Step: Substitute−y−4forxinx+2y=4:
x+2y=4
−y−4+2y=4
y−4=4(Simplify both sides of the equation)
y−4+4=4+4(Add 4 to both sides)
y=8
Step: Substitute8foryinx=−y−4:
x=−y−4
x=−8−4
x=−12(Simplify both sides of the equation)
Answer:
x=−12 and y=8
Answer:35
Step-by-step explanation:
It also means that any angle that is not marked could be acute, right, or obtuse. For example, if this diagram appears without further comment
6*(3/2)=9
so, the answer is c
Answer:
-4x^3 - 4y^2
Step-by-step explanation:
-5y^2 + 5 - 4 - 4y^2 + 5y^2 - 4x^3 - 1
= -4x^3 -4y^2
