Functions can be modeled by equations, tables and graphs
The equation that models the function is [tex]y = \frac 14x +1[/tex]The domain of the function is the set of whole numbersThe company should expect 4 box office gross in week 10 How to determine the functionFrom the question, we have the following ordered pairs
(x,y) = (0,1) and (4,2)
The function is a linear function.
So, we start by calculating the slope (m) using:
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
Substitute known values
[tex]m = \frac{2 - 1}{4 - 0}[/tex]
[tex]m = \frac{1}{4}[/tex]
The equation is then calculated as:
[tex]y = m(x -x_1) +y_1[/tex]
This gives
[tex]y = \frac 14(x -0) +1[/tex]
[tex]y = \frac 14x +1[/tex]
The domain of the above function is the set of whole numbers
Substitute 10 for x, to calculate the number of box office gross for week 10
[tex]y = \frac 14 * 10 +1[/tex]
[tex]y = 3.5[/tex]
Approximate
[tex]y = 4[/tex]
Hence, the company should expect 4 box office gross in week 10

Step-by-step explanation:
The parent function, f(x) = 5^x, has been vertically compressed by a factor of one-half, shifted to the left three units and down two unlts.
Choose the correct function to represent the transformation.
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)

A farmer owns a total of 19 ducks and horses.
The ducks and horses have 64 legs altogether.
How many horses are there?
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

What is the domain of the function graphed below?
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.

Gabriel owns a small business selling used books. He knows that in the last week 89 customers paid cash, 20 customers used a debit card, and 30 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
Answer:
.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

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.
Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest form. an=-2 an = an-1 -13 an=
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]

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

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
