Answer:

  $2701.11

Step-by-step explanation:

The buyer owes for taxes for the remainder of the year, 11 days in May and 7 more months: 7 11/30 months out of 12.

  (7 11/30)(1/12)(4400) = (221/360)(4400) = 2701 1/9 ≈ 2701.11

The buyer will owe prorated taxes of $2701.11.

Answer:

1. y=-5x+10

Step-by-step explanation:

if it reflect over the x it changes the y if it reflects over y it changes the x

The function y = f(x), when shifted down by 2 units and then reflected over the x-axis will become g(x) = 5x + 10.

        where : [m] → is slope of line and [c] → is the y - intercept

We have the some sub - questions given in question.

We will solve part [1].

We have -

y = - 5x - 8

Shifting down by 2 units, we get -

y = - 5x - 8 - 2

y = - 5x - 10

Reflection over the [x] axis, would be -

g(x) = - y

g(x) = - (- 5x - 10)

g(x) = 5x + 10

Therefore, the function y = f(x), when shifted down by 2 units and then reflected over the x-axis will become g(x) = 5x + 10.

Answer:

B.

Step-by-step explanation:

Basically, to draw a dot plot, what you do is place one circle above the corresponding value on the number line for each value in the data set, ie. if there is a 0 in the data set, then you would draw one 'dot' above 0 on the number line. If there was another 0, then you would draw another dot above the dot you drew for the first 0, and so on.

The data set given is:

0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 3, 4, 4, 8

If we count the number of each value, then we can say that:

a) there are three 0's

b) there are four 1's

c) there are three 2's

d) there are two 3's

e) there are two 4's

f) there is one 8

Now you could draw this up on a dot plot and compare this with the answers, or you could technically also just look at the dot plots in the multiple choice answers and count each of the values to see which one matches up with the values we defined above. So:

A. There are three 0's (correct), four 1's (correct), three 2's (correct), but there are no 3's - therefor this is not the correct dot plot.

B. There are three 0's (correct), four 1's (correct), three 2's (correct), two 3's (correct), two 4's (correct) and one 8 (correct) - therefor this is the correct dot plot.

We could use the same method to check if C and D were correct; then we would see that C only has two 0's and one 3 and is thus incorrect, and D only has one 3 and one 4, and has an extra value of 5, thus it is also incorrect.

Therefor, the answer is B.

Whilst this method may be used, a quick sketch of the dot plot may be a little easier to work with to compare visually with the answers, however everyone has their own way so try both methods and see what works for you.

''Option B'' shows the correct dot plot.

We have to given that,

A teacher asked her students how many pets they own.

Here are the results:

0,0,0,1,1,1,1,2,2,2,3,3,4,4,4,8

Now, From the data set,

0 is repeat 3 times.

1 is repeat 4 times.

2 is repeat 3 times

3 is repeat 2 times.

4 is repeat 3 times

8 is repeat only 1 times.

Hence, Option B shows the correct dot plot.

Answer:

(x+3)(3x-5)(3x+5)

Step-by-step explanation:

Let's consider the possible rational zeros:  factors of -75 over factors of 9

So one such possible 0 is -3

let's try it and see if it works:

-3   |    9          27          -25       -75

     |               -27             0         75

       ------------------------------------------

           9          0            -25         0

So x+3 is a factor and we have another there which is 9x^2+0x-25 or 9x^2-25

So far we have this as the factored form (x+3)(9x^2-25)

The second factor is a difference of squares so we can factored this more:

(x+3)(3x-5)(3x+5)

--------You could have also done factored by grouping here:

9x^3+27x^2-25x-75

(9x^3+27x^2)+(-25x-75)

9x^2(x+3)+-25(x+3)

(x+3)(9x^2-25)

(x+3)(3x-5)(3x+5)

Answer:

Step-by-step explanation:

9n^3 + 27n^2 – 25n – 75=9n²(n+3)-25(n+3)

                                         = (n+3)(9n²- 25)

but : 9n²- 25 = (3n)² - 5²

by identity : a²-b² =(a-b)(a+b)

now : a =3n  and b = 5 you have : 9n²- 25 = (3n)² - 5² = (3n-5)(3n+5)

Factor the polynomial :

9n^3 + 27n^2 – 25n – 75=(n+3)(3n-5)(3n+5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.

The domain is the horizontal extent, which is from -2 to +2.

The range is the vertical extent, which is -4 to +4.

The relation is indeed a function, and its domain is [-2, ∞), and its range is (-∞, ∞), as you assumed. The verification process aligns with your initial statements.

If the assumed domain is [-2, ∞) and the assumed range is (-∞, ∞), it suggests that you believe the relation is a function that is defined for all real numbers and can output any real number.

To determine whether the relation is indeed a function, we need to check whether each input (x-value) corresponds to a unique output (y-value) and ensure it satisfies the vertical line test. Let's proceed with the verification:

Function Test (Vertical Line Test):Trace a vertical line through the entire graph. If the vertical line intersects the graph at only one point for each x-value, then the relation is a function. If the vertical line intersects the graph at more than one point for any x-value, then the relation is not a function.

Based on the assumed domain and range, it appears that you are considering the relation to be a function defined for all real numbers. In such a case, the relation would be a function by definition, as it assigns a unique y-value to each x-value.

Answer:

23/14

Step-by-step explanation:

42x - 5 = 64

Add 5 to both sides in order to isolate 42x

42x = 64 + 5

42x = 69

Divide 42 from both sides in order to isolate x

x = 69/42

The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.

Answer:

x = 1.64

Step-by-step explanation:

42x – 5 = 64

add 5 to both sides

42x - 5 + 5 = 64 + 5

42x = 69

divide via by 42

x = 69/42

14 different outcomes.

3 blue + 4 red = 7 different marbles you could draw total.

since you have heads or tails possible with each of the 7, you multiply by 2(heads & tails)

7x3=14

Follow below steps:

When selecting a marble from a bag and flipping a coin, we are combining two separate actions that result in a compound event. The number of possible outcomes in the sample space can be calculated by multiplying the number of outcomes for each action. Since there are 3 blue marbles and 4 red marbles, there are 3 + 4 = 7 possible outcomes for drawing a marble. For flipping a coin, there are 2 possible outcomes: Heads (H) or Tails (T). To find the total number of possible outcomes for the combined actions, we multiply the outcomes for drawing a marble by the outcomes for flipping a coin: 7 (marble outcomes) times 2 (coin outcomes) = 14 possible outcomes in the sample space.

Answer:

2 bears, 3 toy cars, and 10 legos

Step-by-step explanation:

We have 2 things going on here:  the NUMBER if toys and the COST of the toys.  They are not similar so they cannot be combined.  We have to have 1 equation represent each.

First, the NUMBER of toys:

We are told that he has 15 toys altogether, and they are bears, cars, and legos.  b = bears, c = cars, l = legos, ok?  The equation for the number of toys is:

b + c + l = 15.  But we are told then that the number of legos is 5 times more than bears, so l = 5b.  We make the replacement:

b + c + 5b = 15 and

6b + c = 15

Next we deal with the COST.  If each bear costs $10, we represent that as 10b; if each car costs $7, we represent that as 7c; if each set of legos costs $13, we represent that as 13(5b) = 65b.  So the equation for the cost is

10b + 7c + 13(5b) = 171 and

75b + 7c = 171

Now we have 2 equations with only 2 unknowns so we solve this system using the method of elimination/addition.  We can cancel out the c terms if we multiply the first equation by -7 to give us the new system:

75b + 7c = 171

-42b - 7c = -105

The c's are gone, leaving us with

33b = 66 and b = 2.

Now sub that in to folve for c:

6(2) + c = 15 and

c = 3.

Sub both of those in to find l:

2 + 3 + l = 15 and

l = 10

Answer:

Option C is correct.

Step-by-step explanation:

We need to multiply the following terms using vertical multiplication method

 3x^2-5x+1

x x^2+2x+4

The vertical multiplication is shown in the figure attached.

The result is: 3x^4+x^3+3x^2-18x+4

So, Option C is correct.

The vertical method of multiplication involves multiplying each digit of one number by each digit of another, one at a time, recording partial results and adding them together for the final result.

To perform multiplication using a vertical method, first write the numbers vertically aligning them properly. We will be multiplying like this:

Start from the rightmost digit of the second number (bottom number) and multiply it with each digit of the first number (top number), advancing from right to left. Record each result underneath, shifted appropriately (similar to 'carry digits' in addition). After fully multiplying by one digit, proceed to the next digit in the second number, remembering to shift your results accordingly. Finally, add all the results together to get the final answer. This is the vertical method of multiplication.

Answer:

1 -> f

2 -> a

3 -> d

4 -> b

5 -> e

6 -> c

Step-by-step explanation:

We are given:

h(x) = 2 - 2x and g(x) = -2^x+2

a) k(x)= (g-h)(x) = g(x) - h(x)

              = -2^x+2 - (2 - 2x)

              = -2^x+2 - 2 + 2x

              = -2^x+2x or 2x-2^x

k(x) = 2x-2^x = (g-h)(x)

So, 2 matches with a

b) k(x)= (g+h)(x) = g(x) + h(x)

              = -2^x+2 + (2 - 2x)

              = -2^x+2 + 2 - 2x

              = -2^x+4-2x or 4 - 2^x -2x

So, k(x) = 4 - 2^x -2x = (g+h)(x)

So, 4 matches with b

c) k(x)= (2h - 2g)(x) = 2h(x) - 2g(x)

              =  2(2 - 2x)-2(-2^x+2)

              = 4 - 4x+2.2^x-4

              = -4x+2^x+1 or 2^x+1-4x

So, k(x) = 2^x+1-4x = (2h - 2g)(x)

So, 6 matches with c

d) k(x) = (h-2g)(x) = h(x) - 2g(x)

         = (2 - 2x)-2(-2^x+2)

         = 2 - 2x+2.2^x-4

         = -2-2x+2^x+1

         = 2^x+1-2x-2

So, k(x) = 2^x+1-2x-2 = (h-2g)(x)

So, 3 matches with d

e) k(x) = (h-g)(x) = h(x) - g(x)

          = (2 - 2x)-(-2^x+2)

              = 2 - 2x+2^x-2

              = -2x+2^x or 2^x-2x

So, k(x) =  2^x-2x = (h-g)(x)

So, 5 matches with e

f) k(x) = (2g+h)(x) = 2g(x)+h(x)

          = 2(-2^x+2) + (2 - 2x)

          = -2.2^x+4 + 2 - 2x

          = -2^x+1+6-2x or 6 - 2^x+1-2x

So, k(x) = 6 - 2^x+1-2x = (2g+h)(x)

So, 1 matches with f

Final answer:

The function formulas are h(x) = 2 - 2x and g(x) = -2x + 2.

Explanation:

h(x) = 2 - 2x

g(x) = -2x + 2

Even function times an even function produces an even function, Odd function times an odd function produces an even function.
