28.26 im not 100% correct i dont think
Answer:
2500 m^3/1 m^2
Step-by-step explanation:
Going from cm to m is just dividing by 100. So 250,000 cm^3/100= 2,500 m^3
2(-8x-2y=-22)
16x+7y=17
-16x-4y=-44
16x+7y=17
3y=-27
y=-9
16x+7(-9)=17
16x+-63=17
16x=80
X=5
Answer:
C
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
Q(- 5, 2 ) → Q'(2, - 5 )
R(0, 5 ) → R'(5, 0 )
S(- 1, 2 ) → S'(2, - 1 )
