Answer:
x=1
y=-1
Step-by-step explanation:
they have already isolated y in both equations
label both equations
y=-x............1
y=3x-4........2
sub 1 into 2
-x=3x-4
-x-3x=-4
-4x=-4
x=1........ 3
sub 3 into 1
y=-(1)
y=-1

Answer:
1 m³
Step-by-step explanation:
The ratio of volumes is the cube of the ratio of corresponding linear dimensions.
Va/Vb = ((2 m)/(8 m))³ = (1/4)³ = 1/64
Va = Vb(1/64) = (64 cu. m)/(64) = 1 cu. m
The volume of figure A is 1 m³.
The First one (A) because it’s a straight line
1.3/13(if you mean jacks queens and kings)
2.1/52
3.1/2
4.1/13
5.1/4
The enthalpy of a reaction can be measured using a Calorimeter
