Noah's cousin is exactly 7 years younger than Noah. Let C represent Noah's cousin age and N represent Noah's age. Age is measure

sukhopar [10]

Answer:

1. f(N) = C ,where C = N - 7

2. The input of the function is x = N

3. The output of the function = y = C = N -7

4. F(C) = N where N = C - 7

5. Input of the inverse function = C

6. Output of the inverse function = N = C - 7

Step-by-step explanation:

Let Noah's cousin age = C

and Noah's age = N

As given ,Noah's cousin is exactly 7 years younger than Noah.

⇒ C = N - 7

a.)

As we know that , A function is a maping of x to y such that f(x) = y

Let x = N , y = C

So, f( x) = y

⇒f(N) = C ,where C = N - 7

b.)

The input of the function is x = N

c.)

The output of the function = y = C = N -7

d.)

A inverse function is a mapping of y to x

i.e change the variable ,

As we have C = N - 7

It becomes

N = C - 7

So the inverse function becomes

F(C) = N where N = C - 7

e.)

Input of the inverse function = C

f.)

Output of the inverse function = N = C - 7

Joel and Matt must together save at least $50.00 to buy a special present for their mother.

tamaranim1 [39]

Answer:

Option (2)

Step-by-step explanation:

Let the savings of Joel = $y

And the savings of Matt = $x

They jointly save at least $50 to buy a special present.

Therefore, equation for this condition will be,

x + y ≥ 50 --------(1)

Joel saves twice as much as Matt.

Equation for this condition will be,

y = 2x ------ (2)

By substituting the value of 'y' in the equation,

x + 2x ≥ 50

Therefore, Option (2) will be the answer.

The solution to an inequality is given in set-builder notation as {x l x > two-thirds}. What is another way to represent this

Sophie [7]

Answer:

correct choice is C ( ,∞).

Step-by-step explanation:

A set-builder notation is a mathematical notation for describing a set by enumerating its elements or stating the properties that its members must satisfy. In your case, the set builder notation {x l x > } means that the set consists of all elements that are greater than.

Consider number line. Plot the point as unfilled circle that goes after > sigh and shade the ray that goes from this point to the right. Then another way to represent this solution is

The Quotient Rule for the derivative is to take the lower function and multiply it by the derivative of the upper function, then subtract from that the upper function multiplied by the derivative of the lower function, all over the lower function squared. For us that looks like this: $f'(x)= \frac{x(0)-8(1)}{ x^{2} }$ . Simplified that's $f'(x)= \frac{-8}{ x^{2} }$ . If we are evaluating that derivative at x = -1, then we have $f'(-1)= \frac{-8}{(-1)^2} = \frac{-8}{1}=-8$
