Dene-
My Progress

Answers

p(x) = (x + 7)
p(-7) = -7 + 7
p(-7) = 0

The required value of function p(x) at x = -7, p(-7) is zero.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
As given that one factor of a polynomial p(x) is (x + 7).,
Since factor x, + 7 also represents one of the zeros of a polynomial function p(x).

So, when one put the value x = -7 in the function, the function gives zero in the outcome.

Thus, the required value of function p(x) at x = -7, p(-7) is zero.

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

Step-by-step explanation:

Given

[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book

[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book

Required

Determine the weight of her math book

To do this, we simply calculate the difference in the weights given.

Math Book= Backpack(with math book) - Backpack (without math book)

[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]

[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]

Take LCM

[tex]Math\ Book = \frac{8 * 169 - 9 * 119}{72}[/tex]

[tex]Math\ Book = \frac{1352 - 1071}{72}[/tex]

[tex]Math\ Book = \frac{281}{72}[/tex]
