Let f(x) = - 13x + 12 and g(x)= x² + 2.--Find f(3)/g(3).f(3)/g(3) = (?)(Type an integer or a simplified fraction.)

mel-nik [20]

We have the next two equations:

$f(x)=-13x+12$

And

$g(x)=x^2+2$

We need to find f(3)/g(3)

First, let's find f(3):

$f(3)\text{ = -13(3)+12 = -27}$

Then g(3):

$g(3)=(3)^2+2\text{ = 11}$

Now, the equation f(3)/g(3) :

$\frac{f(3)}{g(3)}=\frac{-27}{11}$

-27/11 is the result.

7.5" if the width is now 18 that means its value increased by 3 so multiply 2.5 by 3 and its = to 7.5

Write in slope intercept for slope being -5/7 and passes through (-4,-5)

frutty [35]

Answer:

y = -5/7x - 55/7

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Define

Slope <em>m</em> = -5/7

Random point (-4, -5)

y = -5/7x + b

Step 2: Find y-intercept <em>b</em>

-5 = -5/7(-4) + b

-5 = 20/7 + b

b = -55/7

Step 3: Write linear equation

y = -5/7x - 55/7

Let's assume Debbie paid $1700 in interest, while Jan paid $9000.

Debbie Saves = $1700* 0.28

Jan Saves = $9000 * 0.28

Debbie Saves $476 in taxes

Jan Saves $2520 in taxes
