Step-by-step explanation:

yes

Answer 2

The required value of the expression $\frac{a + 2bc}{3a}$  is 74 / 12 or   37 / 6 .

Given that,
The expression $\frac{a + 2bc}{3a}$  is given, The value of the expression at a = 4, b = -5, and c = -7 is to be determined.

What are functions?

Functions is 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,
The given expression
=  $\frac{a + 2bc}{3a}$
At  a = 4, b = -5, and c = -7
$= \frac{4 +2 * -4 * -5 }{3 * 4 } \\= 74 / 12\\= 37 / 6$

Thus, the required value of the expression  $\frac{a + 2bc}{3a}$  is 74 / 12 or   37 / 6 .
