Describe two ways to solve the equation 2(4x-11)=10
shtirl [24]
2(4x-11) = 10

On dividing 2 on both sides

\frac{2(4x-11)}{2} =  \frac{10}{2}

4x-11 = 5

On Adding 11 on both sides:

4x-11+11 = 11+5

4x = 16

On dividing both side by 4

\frac{4x}{4}  =  \frac{16}{4}

x = 4

Second way is:

We can use distributive property as

2(4x-11) = 10

2*4x- 2*11 = 10

8x - 22 = 10

On Adding 22 on both side

8x - 22+22 = 10+22

8x = 32

On dividing both side by 8

\frac{8x}{8}  =  \frac{32}{8}

x = 4

[Calculus, Derivatives] Can a function be differentiable at certain points even if the entire function is not differentiable?
koban [17]

A function is differentiable if you can find the derivative at every point in its domain. In the case of f(x) = |x+2|, the function wouldn't be considered differentiable unless you specified a certain sub-interval such as (5,9) that doesn't include x = -2. Without clarifying the interval, the entire function overall is not differentiable even if there's only one point at issue here (because again we look at the entire domain). Though to be fair, you could easily say "the function f(x) = |x+2| is differentiable everywhere but x = -2" and would be correct. So it just depends on your wording really.
