Answer:
y= 1/2x+1
Step-by-step explanation:
The little lines on each side of the rhombus mean that all the sides are the same length.
We can set line LM and MN equal to solve for X, then we can solve the length of a side.
3x-3 = x+7
Add 3 to each side:
3x = x +10
Subtract x from each side:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
Now we have the value for x, replace x in one of the side formulas:
x +7 = 5+7 = 12
Each side = 12 units.
The perimeter would be 12 + 12 + 12 + 12 = 48 units.
Answer:
15 I think
Step-by-step explanation:
The formula to figure out the percentage increase or decrease is:
<span>(new - old) / old * 100% </span>
<span>new = 60 </span>
<span>old = 72 </span>
<span>(60 - 72) / 72 * 100% </span>
<span>-12 / 72 * 100% </span>
<span>= -1/6 * 100% </span>
<span>= -0.1666... * 100% </span>
<span>≈ -16.667% </span>
<span>Because it is negative, that's a decrease. </span>
<span>Answer: </span>
<span>A decrease of about 16.7%</span>
