The answer is B
2 x 2 = 4
4 x 2 = 8
8 x 6 = 48
8 x 17 = 136
why isn't it C or D?
For C, 8 x 3 = 24 (throwing the 8 in there because the expression is the same as B).
24 x 2 = 48, but 24 x 5 = 120 and 24 x 6 = 144.
It's also the same reason why it's not D, except that the expression goes WAY into the 400's
An equation to model this scenario would be 2s=28, with "s" being the string.
An irrational number is one that can’t be expressed as a simple fraction.
For instance, the first few digits of the square root of two is written as 1.414213562373095... The digits keep going and cannot be expressed as a fraction. But think of 0.33333... That can easily be written as one-third. The distinguishing feature is that there’s no pattern in the digits for the square root of two.
The first two options are integer fractions. We rule those out immediately. The square root of four is tempting, but realize that it is just equal to two. We come to π (pi).
Arguably the most famous irrational number is π, which starts off as 3.14159265358979... Here, there is again no pattern and the digits extend forever. This meets our definition of our irrational.
The "x" intercept is found when you plug in "0" for "y"
-6x + 3(0) = 18.9
-6x = 18.9 (Divide both sides by -6)
x = - 3.15
(-3.15, 0) is your x-intercept
Now plug in "0" for the x
-6(0) + 3y = 18.9
3y = 18.9 (Divide both sides by 3)
y = 6.3
(0, 6.3) is your y - intercept
