Answer:
Step-by-step explanation:
y = - 9
y^2 = (-9)^2 = 81
AND
z = 0.7
z^2 = (0.7)^2 = 0.49
Hope it helped
Answer is D.
As M is the midpoint of A and B; denote A(x,y); then x and y have to matched the two equations below:
(x- 3) : 2 = 2 <=> x = 7 and
(y +10) : 2 = 6 <=> y = 2
Conclusion : A (7,2)
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
R could equal any number, but it has to be higher than 4, because 3+4=7.
