A rational number is a number that can be written as a fraction or "ratio".
It includes the set of integers because all of them have a denominator of 1. A rational number can take on the form of
where b ≠ 0. Terminating and repeating decimals are rational numbers because they too can be written as a ratio; for example, 0.3 =
or 0.3333... =
.
Regroup terms:
y - 2/9 ≤ 5/9
Add 2/9 to both sides:
y ≤ 5/9 + 2/9
Simplify 5/9 + 2/9 to 7/9:
y ≤ 7/9
Answer:1 quarter, 2 dimes and 1 nickel, 5 nickels, 3 nickels and 1 dime
Step-by-step explanation:
Answer:
The possible values are less than 4 but greater than –4
Step-by-step explanation:
If the absolute value of integer number is less than 4 then it is 0, 1, 2 or 3.
so the possible integer numbers are: -3, -2, -1, 0, 1, 2 or 3.
All of them are greater than -4 and less than 4
Answer:
-5i and 5i cannot be roots of the equation, since they are complex.
Step-by-step explanation:
A 3-degree polynomial equation must have 3 roots, if one of its roots is a complex number, then its conjugate must also be a root of the function. The problem already stated two roots, which are reals, therefore the last root must also be real. Using this line of thought we know that -5i and 5i cannot be roots of the equation, since they're complex.
