To find the value of r, Stephen rewrites 3r - 18 = 27 as 3(r - 6) = 3(9). How could this help Stephen reason the value of r? Exp
Leokris [45]

Answer: See explanation

Step-by-step explanation:

We are informed that Stephen rewrites 3r - 18 = 27 as 3(r - 6) = 3(9). This is quite thoughtful of Stephen and it's an easier way to solve the question.

In this case, 3 is a common factor to 3r, 18 and 27. Therefore, we will then have: 3(r - 6) = 3(9).

Since 3 is a common base to both, we are more concerned with the values inside the brackets. This will be:

r-6 = 9

r = 9 + 6

r = 15

Check: 3r - 18

3(15) - 18 = 45 - 18 = 27

Park Crest Middle School has a population of about 400 Eighth Graders.
Kobotan [32]

Answer:

10^3 times

Step-by-step explanation:

Given

Let

P \to Park Crest Middle School

T \to Total

So, we have:

P = 400

T = 406240

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

n = \frac{T}{P}

So, we have:

n = \frac{406240}{400}

n = 1015.6

Approximate

n \approx 1000

As a power of 10, we have:

n = 10^3

For the graph, which are possible functions f and g?
den301095 [7]

The possible functions for f and g are f(x) = 3^{x} and g(x) = (\frac{1}{3} )^{x}

<h3>What is an exponential function?</h3>

An exponential function is a mathematical function of the following form: f ( x ) = p^{x} where x is a variable, and p is a constant called the base of the function. The most commonly encountered exponential function base is the transcendental number e.

Analysis:

If for every value of x being positive and y is a positive whole number and for every x being negative y is a positive fraction, then that exponential function has a whole number base, Other wise it would have a fractional base. From the above explanation, f has (1,3) (positive x and whole number y) and (-1, 1/3) (negative x and positive fraction y). so therefore f has a whole number base and g has a fraction base.

Therefore f(x) = 3^{x} and g(x) = (\frac{1}{3} )^{x}
