The point-slope form of the equation of the line that passes through (-5, -1) and (10,7) is
y+7= -(x-10). What is the
standard form of the equation for this line?
2x - 5y = -15
2x - 5y = -17
2x + 5y = -15
2x + 5y =-17
=

Given a circle with measures of (c, d, and r) and a circle with measures of (c', d', and r'), what is d if c c' = 12 and d' = 0.50? a) 3 b) 6 c) 12 d) 24

X2 + y 2 = 36 x + y = 6 solve the system of equations.

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?
