Answer:
1.4
Step-by-step explanation:
The correct answer is 10.
In order to evaluate any composite function, you need to first put the value in for the inside function. In this case f(x) is on the inside along with the number 3. So, we input 3 in for x in f(x).
f(x) = 2x + 1
f(3) = 2(3) + 1
f(3) = 6 + 1
f(3) = 7
Now that we have the value of f(3), we can stick the answer in for the outside function, which is g(x).
g(x) = (3x - 1)/2
g(7) = (3(7) - 1)/ 2
g(7) = (21 - 1)/2
g(7) = 20/2
g(f(3)) = 10

Answer:
x = -4
y = 3
Step-by-step explanation:
To get the values of x and y, you have to compare both sides of the equation.
For both sides to be equal,
yi must equal 3i
And x equal -4
yi = 3i-------------------------- divide through by i
y = 3
And x = -4'
