The set (0,1) is not countable
Step-by-step explanation:
Let's start with solving for line L using slope-intercept form (y=mx+b)
We can see that the y-intercept is 4, and the slope is rise/run. From point (5,2) to (0,5), the rise is 2, and the run is -5 (it goes backwards 5).
Using this, we can form our equation for Line L: y = -2/5x + 4
Now let's solve for Line M.
There is something very important to notice before we jump into this. Both of these lines (Line L and M) are parallel (they never touch) and therefore will contain the same slope as each other (-2/5). The y-intercept for this equation we can see is -1, as the line touches (0,-1). Now lets form our equation;
Line M: y = -2/5+4
Solving a system of equation means to find two (or more) line's interceptions on a graph (where they meet/touch). Because both of these lines are parallel and never touch each other, there is no definite answer. Therefore our answer is No Solutions.
The boxes checked are right
a) true: In some instances, an irrational number can be added to an irrational number to become rational, but adding a rational number to one will not work
b) false: It only sometimes works
c) true: e.g. square roots --> (√5)² = 5
d) true: a rational number multiplied by any rational number will be rational
e) false: e.g. perfect squares --> √64 = 8
f) true: e.g. √(5/3) = (√5)/(√3) = (√5*√3)/3
