A factory builds a new warehouse that is approximately 1.28x10^5 square feet. Later, they add on 1.13x10^3 more square feet for offices. Use scientific notation to write the total size of the new building.

The correct answer is 1.2913 x square feet.

Step-by-step explanation:

A factory builds a new warehouse that is approximately 1.28 x square feet = 128,000 square feet.

Later, they add on 1.13 x square feet = 1,130 square feet more for offices.

Thus the total size of the new building is given by 128000 + 1130 = 129130 square feet = 1.2913 x square feet.

Thus in scientific notation the total area of the factory is 1.2913 x square feet.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

(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
