The smallest integer that can be added to -2m3 − m + m2 + 1 to make it completely divisible by m + 1 is .

dangina [55]

Recall the polynomial remainder theorem: if $m-c$ is a factor of some polynomial $p(m)$ , then the remainder upon dividing $p(m)$ by $m-c$ is $p(c)$ .

Let $c=-1$ and $p(m)=-2m^3+m^2-m+1$ . The remainder left from dividing $p(m)$ by $m+1$ is

$p(-1)=-2(-1)^3+(-1)^2-(-1)+1=5$

If we subtract 5 from both sides, we'd get a "remainder" of 0, which suggests that we have to add -5 to $p(m)$ to make $m+1$ a factor.

Solve the following system using substitution. Remember to record your answer as (x, y).

natta225 [31]

Answer:

You already have what you are going to substitute, just put the y values from the first equation into the second! Like this:

6x - 5(-2x - 9) = -19

Multiply it out:

6x +10x +45 = -19

Add like terms + simplify:

16x + 45 = -19

16x = -64

x = -4

take that x and put it back into the first equation!!

y = -2(-4) -9

y= 8-9

y= -1

so... your answer is (-4, -1)

hope this helps!

X > 6

→ 6X < 66

→ 6 x 7 < 66

→ 42 < 66 (Correct)

X > 11

→ 6X < 66

→ 6 x 12 < 66

→ 72 < 66 (Incorrect)

X = 11

→ 6X < 66

→ 6 x 11 < 66

→ 66 < 66 (Incorrect)

ANSWER:

X > 6
