Let p (x) = 5x^3+8x^2-7x-6

using factor theorem,
(x+2) is a factor of p (x) only if p (-2) = 0

p (-2) = 5×-2^3+8×-2^2-7×-2-6
= -40+32+14-6
= -40 + 40
= 0
since remainder = 0
therefore (x+2) is a factor of p (x)

Again,
using factor theorem,
(x+1) is a factor of p (x) only if p (-1) = 0

p (-1) = 5×-1^3+8×-1^2-7×-1-6
= -5 + 8 + 7 - 6
= 3 + 1
= 4
since remainder is not equal to 0
therefore (x+1) is not a factor of p (x)

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?
FinnZ [79.3K]
Slope of the line = (0- -5) / 6-3) = 5/3

in point slope form the equation is

y - 0 = 5/3( x - 6)

y = 5/3x - 10

multiply through by 3:-
3y = 5x - 30
In Standard form this is

5x - 3y = 30   Answer

9x^3 - 8x^2 is the answer. to solve this you must distribute the sign across each parenthetical and then add the like terms (all cubed x variables added to cubed variables and all squared x variables added to squared variable)

Josie bought four lollipops for 65 cents each. She paid with a five-dollar bill. How many cents will she get back?
Murrr4er [49]

Answer:

240 cents

Step-by-step explanation:

Given that,

cost of one lollipop = 65 cents

total amount Josie need to paid = 65 * 4 cents = 260 cents

amount Josie gave  = $5

As we know

$1 = 100 cents

$5 = 100 * 5 cents

    = 500 cents

number of cents Josie will get back

500 - 260

240 cents or $2.40

So, Josie will get 240 cents back
