Answer: This is a nonfunction because there are two different x values for the y value of 20 . In order for it to be functional every x value has to have a different y value.
Step-by-step explanation:
I used the Old Change New method and cross multipled
I multiplied $48.76 * 115% (100% + 15%) which equal to 5607.4
So I divided that 5607.4 by 100% and it equals to $56.074 or juat round it to $56
Check: $56 > $48.76 by 15% so the answer is $56 after 15% tip
The number 144 is rational because it can be expressed by 144/1
Answer:
Step-by-step explanation:

Number of curve length needed to round the circle
The length round the circle is the circumference of the circle.
To get the number of curves (n), we simply divide the circumference by the length of each curve.
i.e.
Circumference is calculated as:
So, we have:
Simplify fraction
<em>Hence, </em><em> of the curve length will fit the circle</em>
Add 5x and -3x
2x+8=-10
Subtract 8 from each side
2x=-18
Divide 2 from each side
X=-9
Hope this helps!
