Which equation can be used to solve the matrix equation [1/2 -1/4 2 3/4] [x y] = [2 -4 1 6]

Use a matrix equation to solve the system of linear equations: -2x + 4y= 2, -3x+7y=7 *

Step-by-step explanation:

took the pretest

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
