(1 point) a is an m×n matrix. check the true statements below:

a. the column space of a is the range of the mapping x→ax.

b. the null space of a is the solution set of the equation ax=0.

c. col(a) is the set of all vectors that can be written as ax for some x.

d. the kernel of a linear transformation is a vector space.

e. the null space of an m×n matrix is in rm.

f. if the equation ax=b is consistent, then col(a) is rm.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way

plz mark brainliest

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
