Give a proof for the Consistency Theorem in two steps: (A linear system Ax = b is consistent if and only if b can be written as a linear combination of the column vectors of A.) I) Prove that if b could be written as a linear combination of the column vectors of A, the linear system Ax=b is consistent by writing b as b= a1x1+a2x2+a3x3+...+anxn and examine x (a1) (a2) (a3) II) Prove that the linear system Ax=b is consistent by rewriting Ax

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

the answer is a

step-by-step explanation:

39.00 x 24 = total installment price

carrying installment price - cash price

needed to save the .00/

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
