Is 1.888... an irrational number? (i have a 1 in math :C)
Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

A 1st degree polynomial function whose graph intercepts the y-axis at 8.
Your answer can be anything in the form y = mx+8 where you replace m with any real number.
You start with y = mx+b, and then replace the b with the y intercept 8.
The y intercept is where the polynomial crosses the y axis.
The value of m does not matter. So you could have y = 2x+8 or y = 3x+8 for instance. Replace m with whatever your favorite number is.
We want to find a polynomial of 1st degree that passes through the y-axis at y = 8.
The polynomial is: y = a*x + 8
Where the coefficient a can be any real number different than zero.
Let's see how to find that polynomial.
Remember that the degree of a polynomial gives us information of the maximum exponent that the polynomial has.
So if the degree is 1, then the polynomial maximum exponent is 1.
From this we can conclude that the polynomial will be something like:
y = a*x + b
Now, this is just a linear equation, where a is the slope and b is the y-intercept.
We do know that this intercepts the y-axis at 8, then we define b = 8, and we get:
y = a*x + 8
This is our polynomial, where the value of a can be any real number different than zero (we use that restriction because if a = 0, then the degree of the polynomial would not be 1).

Tim is 3 years older than his sister. Five years ago the sum of their ages was
19. How old is Tim now?
please include equation
Answer:
Step-by-step explanation:
If Tim is 3 years older and five years ago, the sum of their ages is nineteen you need to find two addends that are 3 greater than each other.
So, 11+8 = 19
Five years ago Tim was 11 and his sister was 8.
add 5 to 11 = 16
Tim is 16 now
I don't know the equation though sorry
Hope this helps you :)
