Answer:

Option 4 (±1, ±1/3, ±3, ±9) is the correct option.

Step-by-step explanation:

The given expression is f(x)=3x^{4}+x^{3}-13x^{2}-2x+9

We have to find the possible rational zeros for the function.

So by the rational zero theorem factors will be

=±(Factors of constant term 9)/±factors of coefficient of x^{4}

=±(Factors of 9)/±(Factors of 3)

=±(1, 3, 9)/±(1, 3)

=±(1, 3, 9, 1/3)

So option 4 is the correct answer.

Find the slope of the line
Schach [20]

Answer:

The slope of the line is: 3

Step-by-step explanation:

Given the points

(-3, -6) and (3, 12)

Determine the slope between (-3, -6) and (3, 12) using the formula

m=\frac{y_2-y_1}{x_2-x_1}

where

m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

  • (x₁, y₁) = (-3, -6)
  • (x₂, y₂) = (3, 12)

now substitute (x₁, y₁) = (-3, -6) and (x₂, y₂) = (3, 12) in the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{12-\left(-6\right)}{3-\left(-3\right)}

m=\frac{12+6}{3+3}

m=\frac{18}{9}

m=3

Therefore, the slope of the line is: 3

Evaluate 1/3 * 5/6 in fraction form
andreev551 [17]

Answer:

= 6 over 23 (or = 6/23

Step-by-step explanation:

Convert mixed numbers to improper fractions 3 5/6 = 23/6

Convert element to fraction

= 1 divide 23/6

Apply the fraction rule: a/b divide c/d = a/b x d/c

= 1 over 1 (or 1/1) divide 23/6

Apply rule a/a = 1

= 1 over 1 (or 1/1) x 6/23

Multiply 1x 6/23 = 6/23

= 1 x 6/23

ANSWER 6/23

Hope this helps!

No comprendo. I'm doing a test review and I'm screwed​
MAXImum [283]

Answer:

x = 5

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin 53 = 4/x

Multiply each side by x

x sin 53 = 4/x *x

x sin 53 = 4

Divide each side by sin 53

x sin 53 / sin 53 = 4 / sin 53

x = 4 /sin 53

x = 5.008542633

To the nearest whole number

x = 5

-4(2x + 4) > 8x + 64
romanna [79]

Hello there I hope you are having a great day :)

Your Question, -4(2x + 4) > 8x + 64 Solve for X

1) Expand -8x-16>8x+64

2) Add 16 to both sides -8x-16+16>8x+64+16

3) Simplify -8x>8x+80

4) Subtract 8x from both sides -8x-8x>8x+80-8x

5) Simplify -16x>80

6) Multiply both sides -1 (Reverse the inequality) (-16x) (-1) >80 (-1)

7) Simplify 16x<-80

8) divide both sides by 16   16x/16 <  -80/16

9) Simplify x < -5  

This should be your answer x < -5

Hopefully that helps you :)
