Answer:
( 3 , -5 )
Step-by-step explanation:
The volume of the new rectangular prism would be 270 cubic centimeters. The reason for this is that when only one dimension is changed, the overall volume is only changed by that same relationship. Because only the height was cut in half, this would be only one of the dimensions.
Answer:
y = -x + 3; could also be y + 1 = -(x - 4) or y = -(x - 4) - 1 or x + y = 3
Step-by-step explanation:
No options given, so I hope this helps.
1. Identify any of the equations that have the same slope as your given equation (-1). If there's only one, stop here.
2. Find the y-intercept by replacing (x,y)=(4,-1) in the equation y = -x + b and solve for b: -1 = -(4) + b ==> 3 = b
3. Replace b in the equation y = -x + b with 3.
So we have 2 large windows, each needing 3 3/4 yds of fabric....and 3 small windows, each needing 1 1/3 yds of fabric
2(3 3/4) + 3(1 1/3) =
2(15/4) + 3(4/3) =
30/4 + 12/3 =
7 1/2 + 4 =
11 1/2 (or 11.5) yds of fabric are needed <==
