To solve this equation we must first plug in 5 for x.

<span> (5 - 4x)
</span>↓

(5 - 4 · 5)
The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

(5 - 4 · 5)

(5 - 20)
The next step would be to subtract both of the numbers within the parenthesis.

(-15)
Now we must multiply.
-

· 15 = -

-

Now we simplify our answer to get our final answer.
-5
Answer:
x = 10.6
Step-by-step explanation:
5x - 11 = 42
first +11 so,
5x = 53
then ÷5
x = 10.6
Answer:
The second function represents an even function; 
Step-by-step explanation:
A function f(x) is said to be even if f(x) = f(-x). All we need to do is replace x with -x in each equation, simplify it and assess whether the equation remains unchanged. If the equation is identical to the original one then it is said to be even. Another good example of an even function is the cosine function. Moreover, even functions have y-axis symmetry
