Ответ:
Translating this verebal statement into a symbolic statement:
8 - 15/y = 13y.
Note: your statement would sound better if written as "8 minus the quotient of 15 and y equals the product of y and 13."
Ответ:
given polynomial 80b^4 – 32b^2c^3 + 48b^4c.
to find: factor put gcf.
solution: in order to factor a gcf of ploynomial, we always look over coefficent of each term and factor out gcf of those coefficents .
then we choose first variable terms in all terms and find gcf of first variable terms.
then choose another variable and factor out gcf of those terms.
david choose 80, 32 and 48 and factored out gcf of those numbers as 16.
so first step is taken by david is correct.
then he choose b variable factors b^4,b^2, b^4 and found gcf b^2 which is correct.
then in third step he choose c^3, and c and found gcf c.
here devid mistaken. there are three terms and we need to take gcf of variable(s) that would be all terms.
variable c is not there in first term 80b^4.
therefore, final gcf would be just product of gcf found in first two steps.
that is 16 times b^2 = 16b^2.
therefore, following statements would be correct statements :
a)the gcf of the coefficients is correct.
b)the variable c is not common to all terms, so a power of c should not have been factored out.
c) in step 6, david applied the distributive property.
