For this case we have the following functions:

f (x) = 3x ^ 3-7x ^ 2-9x + 21\\g (x) = 3x-7

We must find the value of the following expression:

\frac {f (x)} {g (x)}

So:

\frac {f (x)} {g (x)} = \frac {3x ^ 3-7x ^ 2-9x + 21} {3x-7}

Looking at the attached image we have to:

\frac {f (x)} {g (x)} = x ^ 2-3

Answer:

Option D

HURRYY!!! Identify the zeros of f(x) = (x − 3)(x + 9)(4x − 3).
tiny-mole [99]

Answer:

The value of x is -9, 3/4 and 3.

Step-by-step explanation:

In order to find the value of x, tou have to let f(x) equals to 0 :

Let f(x) = 0,

(x-3)(x+9)(4x-3) = 0

x - 3 = 0

x = 3

x + 9 = 0

x = -9

4x - 3 = 0

4x = 3

x = 3/4

9x+y=28<br> 3x+3y=(-12)<br> Solve using elimination
Rzqust [24]

Answer:

(x, y)=(4,-8)

Step-by-step explanation:

9x+y=28

3x+3y=-12 /:(-3)

9x+y=28.......(1)

-x-y=4......(2)

9x+y=28

(1)+(2): 8x=32

9x+y=28

x=32/8

9x+y=28

x=4

9*4+y=28

x=4

36+y=28

x=4

y=28-36

x=4

y=-8

x=4

(x, y) =(4,-8)

1) \overline{AB} \cong \overline{CD}, \overline{AD} \cong \overline{CB}, \overline{AX} \perp \overline{BD}, \overline{CY} \perp\overline{BD} (given)

2) \overline{BD} \cong \overline{BD} (reflexive property)

3) \triangle ABD \cong \triangle ACDB (SSS)

4) \angle ADB \cong \angle CBY (CPCTC)

5) \angle CYB and \angle AXD are right angles (perpendicular lines form right angles)

6) \triangle CYB and \triangle AXD are right triangles (a triangle with a right angle is a right triangle)

7) \triangle AXD \cong \triangle CYB (HA)

8) \overline{AX} \cong \overline{CY} (CPCTC)

-16 + 5n= -7(-6 + 8n) + 3
Amiraneli [1.4K]

\text{Hello there!}\\\\\text{In this question, we're trying to solve the equation}\\\text{We would use the distributive property and solve after that}\\\\\text{Lets solve:}\\\\-16 + 5n= -7(-6 + 8n) + 3\\\\\text{Distribute the -7 to the numbers inside the parenthesis}\\\\-16 + 5n= 42 -56n + 3\\\\\text{Add 56n to both sides}\\\\-16 + 61n= 42  + 3\\\\\text{Add 16 to both sides}\\\\61n= 42  + 3 + 16\\\\61n= 42  + 3 + 16\\\\61n= 45 + 16\\\\61n = 61\\\\\text{Divide both sides by 61}

n = 1
