If you wanted to eliminate the y-variable, what should your next step be? 3x-6y=12 4x-7y=8

Luba_88 [7]

You have to subtract 6y from both sides or subtract 7y from both sides(if you wanted to have a negative).

Use the Remainder Theorem to find the reminder when P(x)=x3+4x2+1 is divided by (i+1)x+2.

Alex777 [14]

First, rewriting a bit,

$\dfrac{x^3+4x^2+1}{(i+1)x+2} = \dfrac1{i+1} \cdot \dfrac{x^3+4x^2+1}{x+\frac2{i+1}}$

By the remainder theorem, the remainder upon dividing $x^3+4x^2+1$ by $x+\frac2{i+1}$ is equal to

$\left(-\dfrac2{i+1}\right)^3 + 4\left(-\dfrac2{i+1}\right)^2 + 1 = \boxed{3 - 6i}$

which is to say,

$\dfrac1{i+1} \cdot \dfrac{x^3+4x^2+1}{x+\frac2{i+1}} = q(x) + \dfrac{3-6i}{(i+1)\left(x+\frac2{i+1}\right)}= q(x) + \dfrac{3-6i}{(i+1)x+2}$

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

$(5x)+(23+90-18)=180$
$5x+95=180$

Step 2: Subtract 95 from both sides.

$5x+95-95=180-95$
$5x=85$

Step 3: Divide both sides by 5.

$5x/5=85/5$
$x=17$

Step 4: Check if solution is correct.

$(5*17-18)+23+90=180$
$67+23+90=180$
$180=180$

Thus, x = 17.
