Section B: Multiples and factors 1. Why is the number 17 classified as a prime number?

Can someone please help me solve this? 2x+5y=-1 -10x-25y=5

fredd [130]

this is system of equations

2x + 5y = -1 times this one by 5 to make the y's opposite

-10x -25y = 5

10x - 25y = -5 (this is it times by 5, now add them)

__________

0 + 0 = 0

now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

Answer:

The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.
