Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
Answer:

Step-by-step explanation:
The blue line represent the full line length.
We can add the parted black segments together and set it equal to the line.





Answer:

Step-by-step explanation:
<u>Directly Proportion</u>
It's said that y varies directly proportional as x, if:

Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:

Solving for k:
k=14
Thus, the equation is:

Answer:
B
Step-by-step explanation:
the dot is placed in the middle between 1 and 0 so that would equal 1/2 which is 0.50
Let w = width of the rectangle
<span>4w+7 = length of the rectangle </span>
<span>perimeter = 2 lengths + 2 widths </span>
<span>2w + 2(4w+7) = 54 </span>
<span>2w + 8w + 14 = 54 </span>
<span>10w = 40 </span>
<span>w = 4 </span>
<span>4w+7 = 23 </span>
<span>dimensions of rectangle: </span>
<span>width = 4 </span>
<span>length = 23 hope this helps</span>
