QUESTION POSTED AT 18/01/2020 - 07:20 AM

The answer is (2,9).

This is because we can increment X by 1, giving us X=2. We can then do:

f(2)=25•(3/5)^2

Which equals:

f(2)=25•(3^2/5^2) because (a/b)^c = a^c/b^c.

We can then calculate the fraction in a simplified form:

f(2)=25•(9/25)=225/25

which fully simplified gives us

f(2)=9/1=9

QUESTION POSTED AT 17/02/2020 - 12:36 PM

**Answer: **Hello!

ni this problem i consider that the notation 21 1/2 is equivalent to 21 + 1/2 = 21.5

our phrase is:

**"The difference between a number and 21 1/2 is no more than 14 1/4"**

we can break it into two parts to make it easier.

**"The difference between a number and 21 1/2"**

this is a subtraction, here you are subtracting 21 1/2 to a number, let's call this number x, then we can write this as:

x - 21 + 1/2

or x - 21.5

the second part says: **"is no more than 14 1/4"**

then the thing that we got before, is less or equal than 14 1/4 (or 14.25), this is

x - 21.5 ≤ 14.25

now you can add the same number in both sides of the inequality and it remains the same, then you can add 21.5 to both sides and:

x - 21.5 + 21.5 ≤ 14.25 + 21.5

x ≤ 35.75

So you need to do 3 things.

First, find craigs distance by adding up the sides.

1)

C = 42 + 56 = 98

Then, find the direct distance, D. This can be done using Pythg. Theorem.

2)

D = √(42²+56²) = 70

3) Now just find the difference.

A = 98 - 70 = 28

A = 28!

So the goal here is to find the value of "w". The first thing you must do is transpose the number 9 to the side of -7 and it would look like this, 4w = -7 - 9. Change the positive sign of the number 9 to negative when you transpose. Then, the equation will be simplified and it will look like this, 4w = -16. Then lastly, to get the value of "w", you must divide the equation to 4 and it will be like this,

__4w__ = __-16 __ so you will get the answer w = -4. I hope this helps you
