The answer to the equation is

y=1700s+18n and y is the total salary including monthly and number books sold

then to graph it just plug that equation I gave you into your graphing calculator and it will show you the graph. Or you can do it by hand and just make a S and N table and plug in values like starting with 0 or 1 and go up 0,1,2,3,4,etc. for each S and P and you will get the corresponding graph coordinate points to plot. Hope this helps! Please rate thank you!!

PLEASE HELP QUICK :) multiple choice.

Answer:

C. f(x) = x³ + 10x² + 7x - 18

Step-by-step explanation:

If the function has a factor of x + 9, then the function will have a zero output at x = -9

<u>Lets verify:</u>

A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, No
C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No

Simplify (–x2 +5) – (3 – 4x2)

lys-0071 [83]

$(-x^{2} +5)-(3-4 x^{2} )$
To simplify this, use the FOIL method. First, Outer, Inner, Last.
First: Multiply the first numbers in each set of parentheses.
$-x^{2} *-3=3 x^{2}$
Outer: Multiply the two outermost numbers in the equation.
$-x^{2} *-4 x^{2} =5 x^{4}$
Inner: Multiply the two innermost numbers in the equation.
$5*-3=-15$
Last: Multiply the last numbers in each set of parentheses.
$5*-4 x^{2} =-20 x^{2}$
Then, we put them all together in an equation, from the highest exponent to the lowest, then highest prefix (number before the variable) to lowest.
$5 x^{4} -20 x^{2} +3 x^{2} -15$
And simplify.
$5 x^{4} -17 x^{2} -15$

What is 9 3/4 - 6:00

Pavlova-9 [17]

3/4 is 45 minutes, cause a quarter of an hour is 15 minutes. 6-9 = -3 so you basically do Noon subtracted by another 3 hours which is 9 am, then subtract those 45 minutes

6pm - 6 hours = 12pm
(Noon) 12pm - 3 hours= 9am
then 45 minutes
9am - 45 minutes
8:15AM
