Answer:

6 ducks and 13 horses

Step-by-step explanation:

Let H and D be the numbers of Horses and Ducks, respectively.

We are told that:

H + D = 19

Our biology book confirms that:

1 horse = 4 legs, and

1 duck = 2 legs

[In most cases on Earth]

So we can say that:

4H + 2D = 64 legs

Rewrite

H + D = 19 as:   H = 19 - D

and then substitute:

4H +2D = 64 legs

4(19-D) +2D = 64 legs

76 - 4D + 2D = 64 legs

-2D = - 12

D = 6  [We have 6 ducks]

Then:

H + D = 19

H + 6 = 19

H = 13  [There are 13 horses]

=============================

Check:

Do 6 ducks and 13 horses have a total of 64 legs?

6*2 + 4*13 = 64?

12 + 52 = 64?

YES

Answer:

f = 9.25 (I think but maybe I read f(4) wrong)

Step-by-step explanation:

so f(4) means x = 4.

The new equation is

f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37

Then solve

F = 9.25

Answer:

$64

Step-by-step explanation:

1/4 means 25%

$48 means 75%

$48 divided by 3 equals 16

$48 plus 16 equals $64

Answer: Choice C

[tex]\displaystyle g(x) = \left(\frac{1}{2}\right)5^{x+3}-2[/tex]

=====================================================

Explanation:

The 1/2 out front handles the vertical compression by 1/2. For example, if two points are vertically spaced by 10 units, then their new vertical distance is now (1/2)*10 = 5 units.

The x+3 in the exponent means "shift 3 units to the left". Effectively what's going on is that the old input x is now x+3, ie 3 units larger than before. This shifts the xy axis itself 3 units to the right. If we held the curve fixed in place while the xy axis moved like this, then it gives the illusion the curve is moving 3 units to the left.

Then finally the -2 at the very end shifts the curve down 2 units. This is because whatever the y coordinate is, we subtract 2 from it to do this vertical shifting. For example, the point (0,62.5) shifts 2 units down to (0,60.5)

.22 chance next customer pays with credit card

Step-by-step explanation:

This is because there was in all 139 customers during that week, and 30/ 139 0.21582733812. This rounded to hundredth would be .22

Answer:

Let the denominator be x

x-18/x=2/5

5(x-18)=2x

5x-90=2x

Answer:

Step-by-step explanation:

Answer:

option C.

Step-by-step explanation:

option C is the correct answer.

Direct variation: y = kx .........where k is constant.

10 = k * -5

k = -2

Then check if all are linear and matches.

y = -2 * -4

y = 8 ...matches.

then

y = -2 * -3

y = 6 ........matches

then

y = -2 * -2

y = 4 ........matches

then

y = -2*-1

y = 2 ......matches as well. so direct variation.

Answer:

The fraction is the area of the cross section and multipling by the height to get the volume= 17/2=8.5 unite cube

Formula for volume is length × width× height

Length ×width is the area, and the area is given so you just times that to the height

Step-by-step explanation:

a) Fred → 35 years old

James → J years old

(3 × J) - 1 = 35

3J - 1 = 35

b) the number of people (n) Anita can invite depends on her age (A) and you add (+) 2.

therefore, n= A +2

2.a) n represents the no of phones he sells.

so if he charges $10 for a phone, then

n × 10 will represent the amount of money he makes for the no of phones he sells. you are given that P represents the amount of money he makes from selling a phone which is 10N and also his weekly salary, $ 250. this is the amount of money he receives for the whole week.

Hence, 10n + 250 = P

ans: P= 10n + 250

b) the next week he sells 20 phones. he charges $10 per phone. then he will make $200 from selling the phones. but he will also receive his weekly salary, which is $250. total money he receives equals $450.

a better way to reach the answer is using the above equation:

P = 10n + 250, where n= 20

P= (10*20) + 250

P= $450

hope you understand this now,

Answer:

[tex]3h=54[/tex]

Step-by-step explanation:

To get the product between 3 and Han's score (h), we multiply them:

[tex]3~x~h~--> 3h[/tex]

And since we know that this product is equal to 54, we'll have that the equation that corresponds to the situation is:

Role plays are a strategy to understand the points of view of other people according to their thinking or the context in which they live.

An argument is a statement that is characterized by being very well supported by verifiable facts. When we want to defend our position, we must argue it through statements that validate our point of view.

Answer:

The domain is the set of x values for which the function resides in.

In this graph, it is unclear as to if the function goes on to infinity, but if it does, the answer is quite easily:

(-2, 4] and [7, ∞)

since the function starts on the left at -2 then continues to the right, with a pause, then indefinitely after.

From the recursive rule

[tex]a_n = a_{n-1}-13[/tex]

it follows that

[tex]a_{n-1}=a_{n-2}-13 \implies a_n = a_{n-2} - 2\times13[/tex]

[tex]a_{n-2}=a_{n-3}-13 \implies a_n = a_{n-3} - 3\times13[/tex]

and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

[tex]a_n = a_1 + (n-1)\times13[/tex]

so that the explicit rule for the n-th term in the sequence is

[tex]a_n = -2 + 13(n-1) \implies a_n = \boxed{13n-15}[/tex]
