When 12x² + kx + 3 and 3x³ + (3k + 2)x² + 28x +17

Naily [24]

Answer:

$\boxed{\sf \ \ \ k=5 \ \ \ }$

Step-by-step explanation:

Hello,

We know that for a real, the polynomial P(x) divided by (x-a) the remainder is P(a)

and as

$3x+2=03x=-2x=\dfrac{-2}{3}$

so we need

$12(\dfrac{-2}{3})^2+k(\dfrac{-2}{3})+3=3(\dfrac{-2}{3})^3+(3k+2)(\dfrac{-2}{3})^2+28\dfrac{-2}{3}+17\\ \ multiply \ by \ 9\\ 12*4-6k+27=-8+4(3k+2)-28*2*3+17*9\\ -6k+48+27=-8+12k+8-168+153\\ -6k+75=12k-15\\ 18k=75+15=90\\ k = \dfrac{90}{18}=\dfrac{15}{3}$

hope this helps

As a salesperson, you are paid $100 per week plus $3 per sale. This week you want your pay to be at least $160. Write an inequal

Svet_ta [14]

First, you would need to create an equation for this problem. Let x represent the number of sales made.
$100 + $3x = $160

Next, you would need to isolate the x.

Subtract $100 from both sides.
$3x = $60

Now, all you would need to do is divide both sides by $3.
x = 20

You would need to make at least 20 sales.

I hope this helps!

An equation is shown 5 x + 3x equals 5x + 15 / 2 what value of 3 x makes this equation true

Ipatiy [6.2K]

3x would have to be 15/2.

Since we have that 5x+3x=5x+15/2, the only pieces that are different are the 3x and the 15/2. This gives us the equation

3x=15/2

If we were to go on and solve this equation, we would multiply by 2, giving us
6x=15

Then we would divide by 6:
6x/6=15/6
and x=2.5.
