Answer:C 4x-y=2
Step-by-step explanation:
Rachel needs 1776 inches of board
<em><u>Solution:</u></em>
Given that, Rachel is making a planter box
Her box measures 345 inches long and 543 inches wide
Length = 345 inches
Width = 543 inches
<em><u>To find: Inches of board she needs</u></em>
So we need to find the perimeter of the board
The board is usually of rectangular shape
<em><u>Perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(345 + 543)
Perimeter = 2(888)
Perimeter = 1776
Thus she needs 1776 inches of board

Answer: 
Step-by-step explanation:
When the scientists detect a signal frequency from the ocean floor, then the depth of submarine =
feet
=
feet
When they dive farther to check the signal, then the depth of the submarine=
feet.
The net change in their elevation =
This is the same question as from DINW 220, but I will answer.
This form of the straight line is an equation through the two points and it reads => y-y1= (y2-y1)/(x2-x1) (x-x1), point 1 (-16,8) and poin2 (4, -2) , x1= -16, y1= 8, x2= 4 and y2= -2 =>
y-8 = (-2-8)/(4-(-16)) (x-(-16)) => y-8= -10/(4+16) (x+16) =>
y-8= (-10/20) (x+16) If we simplify fraction (-10/20) we get (-1/2) =>
y-8=(-1/2) (x+16) we will multiply the both sides of the equation with number (2) we get 2y-16= ( -1) (x+16) => 2y-16= -x -16, we will add to the both sides number (+16) => 2y= -x than divide the both sides with number (2) we get y= (-1/2)x where -1/2 is coefficient of direction or (slope) and this linear function have not cut on the y axis, because it goes through a coordinate start ( 0,0) in the decartes coordinate system.
