<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The expression that is equivalent to (f·g)(2) is,

f(x) = 7x²-3

g(x) = 5x

(g·f)(x) = g(f(x)) = 5(7x²-3)

= 5(7·2² - 3)

Hence, the correct expression is B.

Answer:

x=70

y=75

Step-by-step explanation:

2x+x+5-35=180

3x-30=180

3x=210

x=70

2(70)-35=105

180-105=75

The Baltimore Zoo feeds their elephants a combination of fruit and grass. The zookeeper would like to create a model to represen

Anika [276]

A function can be represented on a table and on a graph.

The models of the linear relationship between f(x) and x are:

$\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}$

The given parameters are:

$\mathbf{Start = 22}$

$\mathbf{Additional = 30}$

So, the function that models the linear relationship is:

$\mathbf{f(x) = Start + Additional \times x}$

Substitute known values

$\mathbf{f(x) = 22 + 30 \times x}$

Evaluate all products

$\mathbf{f(x) = 22 + 30x}$

Rewrite as:

$\mathbf{f(x) = 30x + 22}$

By comparing the above function to the list of options, we have the true options to be:

$\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}$
