If matrix a has dimensions 2 x 4 and matrix b has dimensions 1 x 4, can these matrices be multiplied?
yes or no

No, This matrices cannot be multiplied.

Step-by-step explanation:

If Matrix A has dimensions 2 x 4 and Matrix B has dimensions 1 x 4.

Dimension of matrix A = 2 x 4

Dimension of matrix B = 1 x 4

Multiplication rule.

Two matrices can only be multiplied when row number of one matrix equal to column number of other matrix.

In this case only 4 is common but both of them are column numbers. So these matrices cannot be multiplied.

No, This matrices cannot be multiplied.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
