Solve the system of equations by graphing.

{y=x2−2x−8y=2x−3

Use the Line tool to graph the line.

Use the Parabola tool to graph the parabola. Choose maximum or minimum point first and then a point on the parabola.

Use the Point tool to graph the solution(s) to the system.

In the diagram below, dab and dac are adjacent angles. if mdac = 25°, what is mdab in degrees? what is mbac in degrees?

The sum of two numbers is 12 and their difference is 18 what are the two numbers

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
