Answer: 4,840,000 square meters

Step-by-step explanation:

Each square has an area of (400m)^2 or 160,000 m^2 each square.

There are 390 squares, so:

(30 squares)*(160,000 m^2/square) = 4,800,000 m^2

4,840,000 square meters comes closest

All of the following ordered pairs satisfy the function rule y = -3x + 2 except _____.

SOVA2 [1]

(-3,12) Because you substitute the 12 in for y and -3 in for x. Then you do you order of operations and you get 12=11 which is false.

identify an equation in point slope-slope form for the line perpendicular to y=3 x+5 that passes through(4,-1)

miss Akunina [59]

Answer:

Perpendicular lines have slope that are negative reciprocals.

The slope of the perpendicular line is M = -1/3.

Step-by-step explanation:

(4,-1) --> X = 4, Y = -1, M = -1/3

y = Mx + b

-1 = (-1/3)*4 + b

-1 = (-4/3) + b

-3/3 = (-4/3) + b

-3 = -4 + 3b

1 = 3b

b = 1/3

y = (-1/3)X + 1/3
