How do you write a less than or not equal to b?
if a is less than and not equal to b, it is written a < bIf a is less than or equal to b, it is written a ≤ b
What is the zero factor theorem?
The zero factor theorem is relatively simple.If you have a a product of two (or more) terms, set to equal zero than one or more of the terms must be zero for the equation to be true.Example 1:ab = 0Either a, b, or a and b must be equal to zero for this equation to be true.i.e., (0)b = 0; a(0) = 0; (0)(0)=0;This works with more complex equations as well.Example 2:(5 - a)(6 - b)=0Either 5-a=0, 6-b=0 , or both (5-a) and (6-b) equal zero.In higher level mathematics this can be very useful, because ex is a constant factor you encounter, but ex can never equal zero. Therefore the other term must be the term that equals zero.i.e., ex(5-x)=0ex != 0, therefore: 5-x=0x=5 is the only value of x that satisfies the equation, thus keeping it true.
If a is greater than b how do you make b2 greater than a2?
Make 'b' a negative number with a higher absolute value than 'a' - for example, a = 4 and b = -5. Then b2 will always be greater than a2.
What is an expression of 4 less than b?
An expression of "4 less than b" can be represented as b - 4. This means you are subtracting 4 from the variable b. For example, if b is equal to 10, then 4 less than b would be 10 - 4, which equals 6.
Evaluate 14b for b equals 5?
14b = 5 b = 5/14
