Question

evaluate the expressin at specific values of their variables

Answer 1

To evaluate an expression at specific values of their variables, simply substitute the given values into the expression and then simplify.

For example, let's evaluate the expression 2x + 3y at x = 5 and y = 2:

2(5) + 3(2)
= 10 + 6
= 16

So, when x = 5 and y = 2, the expression 2x + 3y evaluates to 16.

Answer 2

evaluate a^5 - bc + 4a divided by c when a = 2, b = 3, and c = 8

Answer 3

To evaluate the expression at the given values of its variables (a = 2, b = 3, c = 8), we substitute these values into the expression and then simplify:

When a = 2, b = 3, and c = 8:

a^5 - bc + 4a / c
= 2^5 - (3)(8) + 4(2) / 8
= 32 - 24 + 8 / 8
= 16 / 8
= 2

So, when a = 2, b = 3, and c = 8, the expression a^5 - bc + 4a divided by c evaluates to 2.
