the age of Jane is 80% of the age of Alice. If we add both ages the result is 45. Find the age of Jane and Alice
erma4kov [3.2K]

Answer:

Age of Alice = 25, Age of Jane = 20.

Step-by-step explanation:

Let age of Alice = x

Then age of Jane is 80% of the age of Alice

=> Age of Jane = 80% of x = 80/100 * x = 0.8x

Adding the two ages gives 45.

The two ages are x and 0.8x.

The sum of the two ages is x+ 0.8 x = (1+0.8)x = 1.8x.

=> 1.8 x = 45

Dividing both sides by 1.8, x = 45/1.8

=> x= 25

But x represents the age of Alice.

So age of Alice is 25.

Age of Jane = 0.8* 25 = 20

Verification: Adding the two ages gives 45.

A portion of the graph of f(x) = −x2 − 2x + 8 is shown. Which of the following describes all solutions for f(x)?
Naily [24]

Answer:

(x,-x^2-2x+8) where −5 ≤ x ≤ 3

Step-by-step explanation:

The given function is f(x)=-x^2-2x+8.

We want to select the option that describes all the solutions to the parabola.

The domain of the parabola is −5 ≤ x ≤ 3.

This means that  any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.

This can be rewritten as (a,-a^2-2a+8)

Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:

(x,-x^2-2x+8) where −5 ≤ x ≤ 3.
