Variables are those unknowns which could have more than one value, and Algebraic expression is an expression that contains numbers, variables(EX, x and y) and Operations (EX,-, +).

This is awfully general.  Ruben has or does something.  Whatever.  Let's call that Whatever "r."  Then the expression in question is  "r+10."

If f(x) = x2 + 7x and g(x) = 3x - 1, what is f(g(x))?
Burka [1]

Answer:

f(g(x)) = 9x^2 + 15x - 6

Step-by-step explanation:

We are using function g(x) = 3x - 1 as the input to function f(x) = x^2 + 7x.

Starting with f(x) = x^2 + 7x, substitute g(x) for x on the left side and likewise substitute x^2 + 7x for each x on the right side.  We obtain:

f(g(x)) = (3x - 1)^2 + 7(3x - 1).

If we multiply this out, we get:

f(g(x)) = 9x^2 - 6x + 1 + 21x - 7, or

f(g(x)) = 9x^2 + 15x - 6

What is the slope of the function, represented by the table of values below?
Maslowich
Notice the table of values, thus let's pick two points from it, to check what the slope may be,

\bf \begin{array}{l|ccccccc}
x&-2&\underline{1}&2&\underline{4}&7\\
y&16&\underline{4}&0&\underline{-8}&-20
\end{array}\\\\
-------------------------------

\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~{{ 1}} &,&{{ 4}}~) 
%  (c,d)
&&(~{{ 4}} &,&{{ -8}}~)
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{-8-4}{4-1}\implies \cfrac{-12}{3}\\\\\\ \cfrac{-4}{1}\implies -4

What is the constant term for -2a3b2+5ab5+7b4+8
stiv31 [10]

Hey there!

<u>Constant terms</u> are the terms where no variables are there (only the constant, i.e, the number). So, here the term <em><u>8</u></em><em><u> </u></em><em><u> </u></em>is the constant term because it doesn't have any variables.

Hope it helps ya!
