A.
Getting an exact number for gravel is difficult because it spills and the ground is not usually perfectly level. Thus it would be okay to estimate the amount needed.
Answer:
Step-by-step explanation:
The first part is already solved.
<u>We got the scale factor </u>
<u>Use this to find the missing side:</u>
Answer:
-3x-1y
Step-by-step explanation:
5x - 3y⇒ -2(4x-y)
⇒-2(4x - y) = -8x +2y
5x - 3y -8x + 2y
<u>Combine like terms:</u>
5x- 8x= -3x
-3y +2y = -1x
<u>-3x - 1y</u>
Answer:
y= -4x+4
Step-by-step explanation:
y=mx+b
where x=-1, y=8, and m=-4
8=(-4)(-1)+b
8=4+b
4=b
Thus, y= -4x+4
<h3>
Answer:</h3>
<u>Perimeter of rectangular garden = 2(l + b)</u>
- 2(y + 2 + 4y - 1)
- 2y + 4 + 8y - 2
- 10y + 2.
<u>Hence, perimeter of given garden is 10y + 2</u>.
