Multiplying binomials (×+2) (×-9)
musickatia [10]

Answer:

x² -7x -18

Step-by-step explanation:

In algebra, a binomial consists solely of a sum or subtraction of two monomials.  

To solve the multiplication of two binomials we have to multiply term by term and then simplify common terms.

(x + 2)(x - 9) = x(x) + x(-9) +2(x) + 2(-9) = x² -9x + 2x -18 = x² -7x - 18

F(x)=2x^2+4x-16<br> g(x)=4x^2-16<br> Find (f/g)(x).
Nastasia [14]

Answer:

Step-by-step explanation:

(\frac{f}{g} )(x) = \frac{2x^{2} +4x-16}{4x^{2} -16}

2x²+4x -16 =  2(x²+2x-8); factor 2

                  = 2(x+4)(x-2) ;factor the quadratic equation

4x²-16  = 4(x²-4) ; factor 4

            =4(x²- 2²) ; rewrite 4 as 2²

           = 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)

so now we have:

(\frac{f}{g}) (x) = \frac{2(x+4)(x-2)}{4(x-2)(x+2)} ; simplify (x-2) from numerator and denominator

                                  and 2/4 as 1/2

(\frac{f}{g}) (x) = \frac{(x+4)}{2(x+2)}

Which values of m and b will create a system of equations with no solution? Check all that apply. y = mx + b y = –2x + 3/2
Leni [432]
Lines with no solution are parallel lines....parallel lines will contain the same slope, but different y intercepts.

y = -2x + 3/2....slope (m) = -2 and y int (b) = 3/2
so the line we need will have a slope of -2, but can have any y int EXCEPT 3/2.

m = -2, and b = -1/3 is parallel, no solution
m = -2 and b = -2/3...parallel, no solution

Whats the answer to: 3x + 5y = 2 9x + 11y = 14
valkas [14]

\begin{gathered}\{\begin{array}{ccc}3x+5y=2&|\cdot(-3)\\9x+11y=14\end{array}\\\underline{+\{\begin{array}{ccc}-9x-15y=-6\\9x+11y=14\end{array}}\ \ |\text{add both sides of equations}\\.\ \ \ \ \ -4y=8\ \ \ |:(=4)\\.\ \ \ \ \ y=-2\\\\\text{substitute the value of y to the first equation}\\\\3x+5\cdot(-2)=2\\3x-10=2\ \ \ |+10\\3x=12\ \ \ |:3\\x=4\\\\Answer:\ x=4;\ y=-2\to(4;\ -2)\end{gathered}

{

3x+5y=2

9x+11y=14

∣⋅(−3)

−9x−15y=−6

9x+11y=14

add both sides of equations

. −4y=8 ∣:(=4)

. y=−2

substitute the value of y to the first equation

3x+5⋅(−2)=2

3x−10=2 ∣+10

3x=12 ∣:3

x=4

Answer: x=4; y=−2→(4; −2)

291.87 irrational or rational
aliina [53]
291.87 is rational since the last (decimal) numbers aren't repeating.
If it was repeating (291.877777...) it would be irrational.
