Discontinuities can be recognized by observing at asymptotes. An asymptote is a line where the space between the curve and the line go to zero as single or both of the x or y coordinates inclines to infinity. Graphically, they're holes in the graph. Zeroes are points wherever the graph hits the x axis.

A bag with 2 2/4 ounces of peanuts can make 2/3. It can make one full jar with how many ounces of peanuts
Dmitrij [34]
Three and three fourths ounces of peanuts can make a full jar. If two thirds is 2 2/4 then you divide 2 2/4 by two to get one third of a jar, and that is 1 1/4. Then, you multiply that by three to get three thirds, which would be 3 3/4.

Another method would be to multiply 2 2/4 times 1 1/2 which would give you the same answer

Your answer is 3 3/4

What is 7/x-5 - 3/4x-20 =-3<br> So what is 'x'?
IrinaK [193]
\frac{7}{x-5} -  \frac{3}{4x-20} = -3 \\ \\  \frac{7}{x-5} -  \frac{3}{4(x - 5)} = -3 \\ \\  \frac{25}{4(x - 5)} = -3 \\ \\ 25 = -3 \times 4 (x - 5) \\ \\ 25 = -12 (x - 5) \\ \\ - \frac{25}{12} + 5 = x \\ \\  \frac{35}{12} = x \\ \\ x =  \frac{35}{12} \\ \\

The final result is: x = 35/12 or x = 2.9167.
