the equations above define w and z in terms of a. What is 2wz in terms of a?
w=a+2
z=a

Answers

Answer:  2a^2 + 4a

Work Shown:

2wz = 2*(w)*(z)

2wz = 2*(a+2)*(z) .... replace w with a+2

2wz = 2*(a+2)*(a) ... replace z with a

2wz = 2a(a+2)

2wz = 2a(a) + 2a(2) .... distribute

2wz = 2a^2 + 4a

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Speed is the change in distance if a body with respect to time. It is expressed mathematically according to the question as t = 1/500 × d

To determine the time it will take to travel 800miles, we will substitute d = 800 into the modeled equation.

t = 1/500 × 800

t = 800/500

t = 8/5

t = 1.6

Step-by-step explanation:

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara’s Flower Arrangements            Proportional

White 3 6 9 12 15

Yellow 5 10 15 20 25

Hector’s Flower Arrangements          Not Proportional

White 4 8 12 16 20

Yellow 6 10 14 18 22

Part A

Are the numbers of white and yellow flowers in Cara’s arrangements proportional?

Which equation relates the number of white flowers, w, to the number of yellow flowers, y?

Yes; y=3/5w

Yes; y=5/3w CORRECT ANSWER

No; y=3w+5w

No; y=5+3w

Part B

Are the numbers of white and yellow flowers in Hector’s arrangements proportional?

Which equation relates the number of white flowers, h, to the number of yellow flowers, e?

Yes; e=3/2h

Yes; e=2/3h

No; e=h+2 CORRECT ANSWER

No; e=h−2

They are correct because Part A is 1.666667  thats more than 1 so it cant be the first, and Part B, its the White flowers plus 2 to be Yellow flowers, not -.

Following are the solution to the given question:

Using the proportionate connection theory to model these two tables, we may conclude the first table is proportionate whereas the second is not.Clara's configuration:

                   [tex]\bold{White (w) }\\\\\bold{Yellow (y)}[/tex]

To determine whether a relationship is proportionate, perform the following tests:

                    [tex]\bold{y = kw } \\\\\bold{5 = 3k}[/tex]

Yes, there seems to be a proportional relationship. Hector's set-up is as follows:

                  [tex]\bold{White (h) }\\\\\bold{Yellow (e)}\\\\[/tex]

The number of yellow flowers always out-numbers the number of white blooms by a factor of 2. As a result, the relationship could be modeled as follows;

               [tex]\to \bold{e = h + 2}[/tex]

As a result, the relationship is not proportionate.

what is the factor of 6a2 – 19a + 10 ???

Answers

Answer:

(2a - 5) • (3a - 2)

step by step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60

Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .

-60 + -1 = -61

-30 + -2 = -32

-20 + -3 = -23

-15 + -4 = -19 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4

6a2 - 15a - 4a - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

3a • (2a-5)

Add up the last 2 terms, pulling out common factors :

2 • (2a-5)

Step-5 : Add up the four terms of step 4 :

(3a-2) • (2a-5)

Which is the desired factorization

Final result :

(2a - 5) • (3a - 2)

Answer:

(2a-5) (3a-2) is your correct answer.

How many hours of tutoring will occur before the fees are the same?
How much has each person been paid in tutoring fees?

Answers

Answer:

after 2 hours, they will have the same fee.

they will have been payed 11$

Step-by-step explanation:

if you say  h = hours of tutoring,

Rakim charges 7 + 2h

Joan charges 3 + 4h

since you want them to be the same, you can write the following equation:

7 + 2h = 3 + 4h

subtract 2h from each side

7 = 3 + 2h

subtract 3 from each side

4 = 2h

divide both sides by 2.

h = 2

after 2 hours, they will have the same fee.

they will have been payed 11$

"they will have been payed" ah yes the grammar.

If a translation is described as (x -5, y), how has the original image changed?

Answers

Answer:

It moves the x value 5 units to the left.

Step-by-step explanation:

"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.

Since we are subtracting to the x value, we are going to move left 5 units.

Let's say we had the point (5, 5).

If we use the translation rule;

(5 - 5, 5)

(0, 5)

We moved the x value 5 units to the left.

Suppose that under your health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay. You get sick and are hospitalized for 4 days, and the bill (after your insurance discounts are applied) comes to $6,250. How much of that hospital bill will you have to pay yourself?

Answers

Answer:

$4900

Step-by-step explanation:

It is given that,

According to health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay.

If a person hospitalized for 4 days, it would mean that charges will be ($150 × 4 = $600 per day).

Total amount given by insurance policy = $750 + $600 = $1350

The bill for 4 days come out to be $6,250.

The person have to pay ($6,250-$1350) = $4900 itself.

Answer:

Step-by-step explanation:

The angle measure of 295° just means we are working with a circle.

A circle totals to 360°.

If we add what we are given; 295 + 23 = 318°

We have the total angle measure we are given and "b" which we need to solve.

We can subtract 360 by what we are given to find angle "b"

360 - 318 = 42°

Best of Luck!

It would be 295+23 then u would take that answer and subtract it from 369 considering it is a full circle

Do these pairs of values (x and y) represent two quantities that are
proportional?
A. Yes, because as x increases, y increases.
B. No, because not all of the pairs represent the same ratio.
C. Yes, because the ratios į and i are equal.
O D. No, because not all of the pairs are simplified ratios.

Answers

Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

We want to see if the relationship between x and y is proportional or not.

We will see that the correct option is B:

"No, because not all of the pairs represent the same ratio."

Let's see how to solve this.

First, a proportional relationship is something of the form:

y = k*x

Where k is the constant of proportionality.

So to see if the relationship between x and y is proportional, we can input the pairs on the general proportional relationship.

For the first pair, we have x = 3 and y = 5, then:

5 = k*3

Now we can find the value of k:

k = 5/3 = 1.667

Now let's do the same for the second pair of points, we should get the same constant of proportionality.

7 = k*4

k = 7/4 = 1.75

So we got different constants of proportionality for two different x-y pairs, thus, the relationship is not proportional.

Because k is defined as the ratio between y and x, we can say that the relationship is not proportional because not all of the pairs represent the same ratio.

Thus the correct option is B.
