What is 5b x 12b?
60b2 you multiply the coefficients then the exopnients 5b1 (next to variables there are invisible exonients) x 12b1 ______ 60b2 (when multiplying like variables you add the exponients)
What is x2 multiplied by 2x?
X2 * 2X= 2X3======multiply coefficients and add exponents ( all variables have a 1 as implied exponent )
What is a Characteristic for like terms?
They have the same form for any variables, but the numerical coefficients can be different.
What correlation coefficients express the weakest degree of relationship between two variables?
-.12
What happens when you multiply two variables with different exponents?
When you multiply two variables with different exponents, the exponents are added. For example, if you multiply x^2 by x^3, the result is x^(2+3) = x^5. Similarly, if you multiply x^3 by x^(-2), the result is x^(3+(-2)) = x^1 = x.
What do coefficients stand for?
Coefficients don't 'stand' for anything. They are numbers which multiply variables. For instance, in the expression 3 x + 2, three is the coefficient of x.

What is the key to using the elimination method to find variable terms in the two equations that have equal or opposite coefficients?
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
What is a constant value that are not coefficients of variables to equations?
parameters
Could you multiply constants with coefficients?
yes
What correlation coefficients represents a situation in which there is no relationship between variables?
We would need to have the list of correlation coefficients to respond to this question.
How do you simplify 7 b over 9 b?
You are dividing two monomials. Divide the coefficients of the variables, and multiply by the division of the variables. 7b/9b = 7/9 x b/b = 7/9 x 1 = 7/9
Can we directly multiply two pointer variables?
Only subtract, if they are pointers to the same type. Example:double coefficients [12], *p= &coefficients[3], *q= &coefficients[4];printf ("q-p=%d\n", (int)(q-p));Note: The result is 1, not sizeof (double)
How do you solve variables on both sides-negative coefficients?
-85-6x=91+2x
When factoring out the GCF do variables get factored out as well as coefficients?
Yes, if they are in common for all the terms.
What is a Characteristic for like terms?
They have the same form for any variables, but the numerical coefficients can be different.
