Aglass vase weighs 0.61 lb. how much does a similarly shaped vase made of the same glass weigh if each dimension is 2 times as large? explain. a. 2.44 lb; the vase dimensions are 2 times as large, so the weight is 4 times as much because 2sq = 4. b. 1.22 lb; the vase dimensions are 2 times as large, so double the weight. c. 9.76 lb; the vase dimensions are 2 times as large, so the weight is 16 times as much because 2sq4 = 16. d. 4.88 lb; the vase dimensions are 2 times as large, so the weight is 8 times as much because 2sq3 = 8.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
