First distribute the 1/5 through the parentheses.

1/5 (3 + 2z) - 4z = -3
3/5 + 2/5z - 4z = -3

subtract 3/5 from each side

2/5z - 4z = -3 - 3/5

combine like terms

-3 3/5z = - 3 3/5

z = 1

Theres another answer choice thats four but it got cut out please help pretty easy question

Answer:

We conclude that:

f(g(3)) = 2

Hence, option B is correct.

Step-by-step explanation:

Given the f(x) table

x         2          3            4          5

f(x)      0           1             2         3

Given the g(x) table

x         1           2           3            4

g(x)      1           2            4           8

We need to determine f(g(3)).

In order to determine f(g(3)), first, we need to determine g(3)

It is clear from the table of g(x),

at x = 3, g(3) = 4

so

f(g(3)) = f(4)

Now, we need to check the value of f(4) at x = 4 using the table f(x)

It is clear from the table of f(x),

at x = 4, f(4) = 2

Thus,

f(g(3)) = f(4) = 2

Therefore, we conclude that:

f(g(3)) = 2

Hence, option B is correct.
