There appear to be 13 people with 2/3 sport caps and 6 people with 6/7 sports caps. Just subtract 6 from 13 as shown:
13-6 = 7.
Therefore, 7 more people have 2/3 sports caps than those with 6/7.

The graph shows that 13 friends have 2 or 3 sports caps and that 6 friends have 6 or 7 sports caps.
The question wants you to find the difference between these 2 numbers.
13 - 6 = 7
So there are 7 more friends that have 2 or 3 sports caps than those that have 6 or 7.

Find dy/dx by implicit differentiation. y cos x = 5x2 + 3y2

lbvjy [14]

Step 1:
Start by putting $\frac{d}{dx}$ in front of each term

$\frac{d}{dx}[y cos x]= \frac{d}{dx}[5x^2]+ \frac{d}{dx}[ 3y^2]$
-----------------------------------------------------------------------------------------------------------------
Step 2:

Deal with the terms in 'x' and the constant terms
$\frac{d}{dx}[ycosx]= 10x+ \frac{d}{dx} [3y^2]$
----------------------------------------------------------------------------------------------------------------
Step 3:

Use the chain rule for the terms in 'y'
$\frac{d}{dx}[ycosx]=10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------
Step 4:

Use the product rule on the term in 'x' and 'y'
$(y) \frac{d}{dx} cos x+(cos x) \frac{d}{dx}y =10x+6y \frac{dy}{dx}
$
$y(-siny)+(cosx) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------

Step 5:

Rearrange to make $\frac{dy}{dx}$ the subject
$-y sin(y)+cos(x) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
$cos(x) \frac{dy}{dx}-6y \frac{dy}{dx}=10x+y sin(y)$
$[cos(x) - 6y] \frac{dy}{dx}=10x + y sin(y)$
$\frac{dy}{dx}= \frac{10x+ysin(y)}{cos(x)-6y}$ ⇒ Final Answer

After solving an equation, you end up with integers on both sides of the equation. What can you interpret about the equation are

murzikaleks [220]

Answer:

The equation is:

An identity

Has infinitely many solutions

No solution

Step-by-step explanation:

Because there is integers on both sides, we know that any attempts to fix this will either cause an identity, or a false numerical equation(an identity but <em>w r o n g</em>).(Note, an identity can either mean 2 = 2 or x = x).

Identities have infinite solutions, because it does not matter what you put in, the equation will always be true. False equations do not have a solution because they aren't even true equations.

Hope this helps!

HELP PLEASE ILL TRY TO MARK U BRAINLIEST

Anon25 [30]

Step-by-step explanation and answer:

For this you just need to plug in x for y = f(1/5x)

1/5(-4) = -4/5 or -0.8

1/5(-1) = -1/5 or -0.2

1/5(0) = 0

1/5(3) = 3/5 or 0.6

1/5(6) = 6/5 or 1.2 or 1 1/5

Factor completely <br> 4x^2 + 24x - 64

lara31 [8.8K]

First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is

4(x+8)(x-2)
