On this test, you will be required to perform operations on matrices (addition, scalar multiplication, matrix multiplication), solve matrix equations find the inverse of a 2 x 2 matrix, use the invertible matrix theorem to answer questions about matrices find a basis for the column space of a matrix find a basis for the null space of a matrix, use the coordinates of a vector relative to a basis to find the vector, find the coordinates of a vector relative to a basis, find the rank ofa matrix, and find the dimension of the null space of a matrix. in addition, you may be called upon to write explanations for any or all of your conclusions macbook air fs f6 f7 fb % & e r t y u co 5 ta4 f3

the answer is 37

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
