Answer:

Step-by-step explanation:

If (x - 3) is a factor of the polynomial then f(3) = 0

Given

f(x) = 5[tex]x^{5}[/tex] - 3[tex]x^{4}[/tex] + 2x² - 9x + 12 , then

f(3) = 5[tex](3)^{5}[/tex] - 3[tex](3)^{4}[/tex] + 2(3)² - 9(3) + 12

      = 5(243) - 3(81) + 2(9) - 27 + 12

      = 1215 - 243 + 18 - 27 + 12 = 975

Since f(3) ≠ 0 then (x - 3) is not a factor of the polynomial

Answer and Explanation:

Number of classes = 8

    Highest value =2300

  Lowest value = 1250

Class width= highest value – lowest value / number of classes

               = 2300 – 1250/8

                = 131.25 = 132

So, we can write class as 1250+132=1382

Class                                        frequency

Step-by-step explanation:

Since a large ice chest holds the water = 62 liters

And smaller chest holds the water = [tex]\frac{4}{5}[/tex] of the larger ice chest

                                                         = [tex]\frac{4}{5}\times 62[/tex]

                                                         = [tex]\frac{248}{5}[/tex] liters

Therefore, fraction that represents the amount of ice water in the smaller ice chest will have 0 in the first box, 248 in the numerator and 5 in the denominator.

Answer:

B. The graph has no y-intercepts

Step-by-step explanation:

We see that we have vertical and horizontal asymptotes.

We also see that the right side of the graph has an x-intercept of (2, 0).

Therefore, A and D are incorrect.

We use the vertical asymptote x = 0 to get our answer B, as we will never cross the y-axis as x approaches negative and positive infinity.

Answer:

2.-6

Step-by-step explanation:

1. 11b=89

b=89/11

8.09

2. 13+k/3=11

k/3=11-13

k/3=-2

k=-2*3

=-6

Answer:

Number 2 is - 6

Step-by-step explanation:

2. 13 + k/3 = 11

We can start off my subtracting 13 in both sides.

-13 + 13 + k/3 = 11 - 13

k/3 = -2. now we have to multiply 3 in both sides

3 x k/3 = -2 x 3

k = -6

Answer:

34

Step-by-step explanation:

We can solve this equation by giving Sara's number a variable.

Let it be x.

Then we solve by simply interpreting the problem step by step.

"If you subtract 14 from my number..."

x - 14

"...and multiply the different by -4..."

-4(x-14)

"...the result is -80"

-4(x-14) = -80

Now that we have our equation, we can solve for x.

1.) Use distributive property to expand.

-4x + 56 = -80

2.) Subtract 56 from both sides

-4x = -136

3.) Divide by -4

x = 34

Sara's number is 34

Using distributive property to expand, it is found that Sara's number is; 34

The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

This property is known by distributive law and applies to subtraction also.

We need to solve this equation by giving Sara's number a variable.

Let the Sara's number a variable be x.

Then we solve by simply interpreting "If you subtract 14 from my number..." means

x - 14

Then "...and multiply the different by -4..." means -4(x-14)

"...the result is -80"

-4(x-14) = -80

Now that we have our equation,

1.) Use distributive property to expand;

-4x + 56 = -80

Subtract 56 from both sides;

-4x = -136

Now Divide by -4

x = 34

Hence, Sara's number is; 34

Answer:

h =10

Step-by-step explanation:

3/7 = h/14 -2\7

3/7 = 1/14 h + -2/7

1/14 h + -2/7 = 3/7

1/14 h + -2/7 +2/7 = 3/7 + 2/7

1/14 h = 5/7

14 * ( 1/14h) = 14* (5/7)

h =10
