Solve the system of equations using substitution.

Mathematics
1 answer:
Radda [10]3 years ago
6 0

Answer:

C. No solution.

Step-by-step explanation:

y = −2x + 1

4x + 2y = −1

Substituting y = -2x + 1 in the second equation:

4x + 2(-2x + 1) = -1

4x - 4x + 2 = -1

2 = -1  which is  absurd so there is no solution.

The statement that best describes the information about the medians would be: the class median and exam median are almost the same.

<h3>Median of a Data Set on a Box Plot</h3>
  • The median of any data distribution that is plotted on a box plot is indicated by the vertical line that divides the rectangular box in the box plot.

Thus:

  • The median for class is 84
  • The median for exam is 85.

Therefore, the statement that best describes the information about the medians would be: the class median and exam median are almost the same.

Answer:

M = 42

Step-by-step explanation:
