Hey there!

Since we know that x = 5, we first multiply 5 and 5 . . .

5 * 5 = 25

3 * 5 = 15

25 + 15 = 40 <----

The correct answer is 40.

5x + 3x = 40.

Hope this helps you.
Have a great day!

Hi there again!

Since x = 5, we also plug this into the equation.

5x + 3x
= 5*5 + 3*5
= 25 + 15
= 40

So, the answer is 40.

Hope this helps!

Answer:

.01%*

Step-by-step explanation:

Individually, they both have a rate of failure of 1%.

.01 x .01 = .0001

Therefore they have a combined probability of failure of .01%

I am not the best at this area in math so I would still reference against someone else's answer, but this is my best effort :)

For the functions f(x) = 5x − 3 and g(x) = x + 4, which composition produces the greatest output?
Zina [86]
You could actually find the compositions and thus have something to compare.  You haven't shared the list of possible answer choices.

(f+g)(x) = 5x - 3 + x + 4 = 6x + 1

(f-g)(x) = 5x - 3 - x - 4 = 4x - 7

(f*g)(x) = (5x-3)((x+4) = 5x^2 + 20x - 3x - 12 = 5x^2 + 17x - 12

There are also the quotient (f/g)(x) and the compositions f(g(x)) and g(f(x)).

WRite them out.

Then you could arbitrarily select x values, such as 2, 10, etc., subst. them into each composition and determine which output is greatest.
