Y=3x−9

y=3(0)-9

y=9

Now plug in y to solve for x.

y=3x−9

9=3x-9

18=3x

6=x

The x-intercept is (6,0)

Given the functions below, find (g * h)(1). g(x) = x^2 + 4 + 2x. h(x) = -3x + 2

pshichka [43]

Answer:

Step-by-step explanation:

g(x) = x² + 2x+4

h(x) = -3x+2

(g*h)(1) is the same as

g(h(1)) , next solve for h(1) first by substituting in h(x), x with 1

g( h( x= 1)) = g( -3*1 +2) = g( -1) so substitute in g(x) , x with -1

g(x= -1) = (-1)² +2(-1) +4 =1-2+4 =3

Use the long division method to find the result when 9x^3+18x^2+20x+169x 3 +18x 2 +20x+16 is divided by 3x+43x+4.

fenix001 [56]

Given:

Dividend = $9x^3+18x^2+20x+16$

Divisor = $3x+4$

To find:

The quotient and remainder by using the long division method.

Solution:

Using the long division method, divide the polynomial $9x^3+18x^2+20x+16$ by $3x+4$ as shown below:

$3x+4 |\overline{9x^3+18x^2+20x+16}|3x^2+2x+4\\$

$9x^3+12x^2\\\underline{(-)\quad (-)\quad \quad \quad}$

$0+6x^2+20x$

$6x^2+8x\\\underline{(-)\quad (-)\quad \quad \quad}$

$0+12x+16$

$12x+8\\\underline{(-)\quad (-)}$

$\underline{\quad 0\quad}$

Therefore, the quotient is $3x^2+2x+4$ and the remainder is 0.
