Let x be the first computer. Let y be the first computer. We know that Work = 1 / Time.

If the work together, work can be done in 30 seconds. Thus, we have:
1/x + 1/y = 1/30

If x will finish in 50 seconds, we need to compute how many seconds y can finish the same work. Thus solving for y, we have the equation below:
1/50 + 1/y = 1/30
1/y = 1/30 - 1/50
1/y = 1/75

The second computer can finish the same work in 75 seconds.

Give the function for f(x)-5|x+1|+3 for what values of x is f(x)=-12
Lyrx [107]
I’m not sure whether there is a typo in the function but I might have the answer.

If f(x) = 5(x+1)+3 = -12 then you can solve for x.

5(x+1)+3 = -12
5x + 5 + 3 = -12 << expand the brackets
5x + 5 = - 15 << minus 3
x + 1 = -3 << divide everything by 5
x = -4 << minus 1

I don’t know if this helps x Sorry

Question attached below
tamaranim1 [39]

Answer:

B . f(x+h)=\frac{x+h}{1+x+h}

Step-by-step explanation:

Given function is:

f(x)=\frac{x}{1+x}

Sall h is used to denote minor change in function. The value of the new function f(x+h) will be calculated by putting x+h in place of x in the function.

So putting x+h in place of x

f(x+h)= \frac{x+h}{1+(x+h)}\\=\frac{x+h}{1+x+h}

So, option B is the correct answer ..

Which function is undefined for x = 0? y=3√x-2 y=√x-2 y=3√x+2 y=√x=2
Andre45 [30]

For this case, we must indicate which of the given functions is not defined forx = 0

By definition, we know that:

f (x) = \sqrt {x} has a domain from 0 to infinity.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.

Thus, we observe that:

y = \sqrt {x-2} is not defined, the term inside the root is negative when x = 0.

While y = \sqrt {x + 2} if it is defined for x = 0.

f(x)=\sqrt[3]{x}, your domain is given by all real numbers.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.

So, we have:

y = \sqrt [3] {x-2} with x = 0: y = \sqrt [3] {- 2} is defined.

y = \sqrt [3] {x + 2}with x = 0: y = \sqrt [3] {2}in the same way is defined.

Answer:

y = \sqrt {x-2}

Option b
