If F(x)=4x-1 and g(x)=x^2+7, what is g(f(x))
VashaNatasha [74]
Answer

g(f(x)) = = 16 {x}^{2} - 8x + 8

step by step Explanation

The functions given are

f (x)= 4x- 1

g(x)= {x}^{2} + 7

We want to find:

g(f (x))= g( 4x- 1)

This implies that

g(f (x))= ( (4x- 1)^{2} + 7)

Let us now simplify

( {a - b)}^{2} = {a}^{2} -2ab + {b}^{2}

This implies that

( (4x- 1)^{2} + 7) =( {(4x)}^{2} - 2(4x) \times 1 + 1

Combine the terms to get,

= 16 {x}^{2} - 8x + 1 + 7

= 16 {x}^{2} - 8x + 8

Suppose James has a credit card with a balance of 4289 . Each month the credit card company charges 5% interest. If James pays o
topjm [15]

Answer:

<h2>4076.56</h2>

Step-by-step explanation:

First we need to calculate the James monthly charges on his balance of 4289.

Using the simple interest formula;

Simple Interest = Principal * Rate * Time/100

Principal = 4289

Rate = 5%

Time = 1 month = 1/12 year

Simple interest = 4289*5*1/12*100

Simple interest = 21,445/1200

Simple interest = 17.87

<u>If monthly charge is 17.87, yearly charge will be 12 * 17.87 = </u><u>214.44</u>

The balance on his credit card one year from now = Principal - Interest

= 4289 - 214.44

= 4076.56

The balance on his credit card one year from now will be 4076.56

Answer:

-\frac{9}{15}

-0.7

Step-by-step explanation:

Both -\frac{9}{15} and -0.7 are negative so therefore, 1 is the greatest

-\frac{9}{15} is -0.6 which is greater than -0.7 so it's the 2nd greatest

and -0.7 is the least
