Jay simplify the expression 3x( 3+12÷3)-4 over his first step he added 3+12 to get 15 what was jays error? Find the correct answer

Answers

Answer 1
Answer: Hello there!

To simplify this expression, you must follow PEMDAS.

3x(3+12÷3) parentheses first
3x(3+4) do the division
3x(7) addition inside of parentheses
21x multiplication

This means that Jay is incorrect in doing addition first.

I really hope this helps!
Best wishes :)
Answer 2
Answer: distribute 3x through all the numbers in () then solve for x and you get 21x-4

Answers

Answer:

3

Step-by-step explanation:

    6 cups  require 2 cups

    9 cups require-------x

Cross multiplication

9x2 = 6x

18 = 6x

x= 3

 Another way to think about:

6 + half of 6 = 9

   Then

2+ and half of 2 = 3

   

       6 is 3 times more than 2

        9 is 3 times bigger than 3

Answer:

x = 4

Step-by-step explanation:

The given equation is as follows :

4(3x - 6) = 24

If we want to solve the above equation, the steps are:

Using distributive property first as:

4(3x)-4(6)=24

12x-24=24

Adding 24 both sides,

12x-24+24=24+24

12x=48

x=4

So, the value of x = 4. All given steps are correct.

Consider the function below. f(x) = 6x tan x, −π/2 < x < π/2 (a) find the vertical asymptote(s). (enter your answers as a comma-separated list. if an answer does not exist, enter dne.)

Answers

Answer:

x = −π/2, x = π/2  

Step-by-step explanation:

Given f(x) = 6x tan x and the interval −π/2 < x < π/2, we know that tan x has asymptotes in both extremes of the interval. To find the vertical asymptotes we evaluate the limit in the x-values we think asymptote can appear, in this case for x = −π/2 and x = π/2.

\lim_(x \to\ (-\pi/2)-) 6x * tan x=

=\lim_(x\to\ (-\pi/2)-) 6x * \lim_(x\to\ (-\pi/2)-)tan x=

=-3 \pi * -\infty =\infty  

\lim_(x\to\ (\pi/2)+) 6x * tan x=

=\lim_(x\to\ (\pi/2)+) 6x * \lim_(x\to\ (\pi/2)+)tan x=

=3 \pi * \infty =\infty

Then, x = −π/2  and x = π/2  are vertical asymptotes.

Answer: Does not exist.

Step-by-step explanation:

Since, given function,  f(x) = 6x tan x, where −π/2 < x < π/2.

⇒ f(x) = (6x sin x)/(cosx)

And, for vertical asymptote,  cosx= 0

⇒ x = π/2 + nπ where n is any integer.

But, for any n x is does not exist in the interval ( -π/2, π/2)

Therefore, vertical asymptote of f(x) where −π/2 < x < π/2 does not exist.
