URGENT!!! PLEASE HELP

Mathematics
1 answer:
Molodets [167]3 years ago
3 0

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

Which one of the following measurement represents the longest distance 5m, 10cm, 50mm, 1km
ElenaW [278]

First you need to convert them to one common measurement... I'll use cm for the measurement.

  • 1m = 100 cm
  • 10 cm = 10 cm
  • 50 mm = 0.1 cm
  • 1 km = 100000 cm

Using this info to convert gives

  • 500 cm
  • 10 cm
  • 5 cm
  • 100000 cm

The smallest is 50 mm which is equal to 5 cm

A round mirror has a circumference of 87.92 inches. Calculate the area of the mirror.
Zarrin [17]

\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=87.92 \end{cases}\implies 87.92=2\pi r\implies \cfrac{87.92}{2\pi }=\boxed{r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2~\hspace{7em}A=\pi \left( \boxed{\frac{87.92}{2\pi }} \right)^2 \\\\\\ A=\pi \cdot \cfrac{87.92^2}{4\pi^2}\implies A=\cfrac{87.92^2}{4\pi }\implies A\approx 615.127998
