Answer: Largest element in the domain is 4

The largest number of packages you can buy is 4

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

Explanation:

1 package costs 8.50*1 = 8.50 dollars

2 packages cost 8.50*2 = 17 dollars

3 packages cost 8.50*3 = 25.50 dollars

and so on. In general

x packages cost 8.50*x = 8.50x dollars

where x is a place holder for a positive whole number (1,2,3,...)

The total amount spent is 8.50x and the budget is $40

This means,

[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]

We round down regardless of how close we are to 5.

If x = 4, then 8.50*x = 8.50*4 = 34

While if x = 5, then 8.50*x = 8.50*5 = 42.5

So we see we go over budget if we buy x = 5 packages.

This makes x = 4 the largest in the domain.

Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).

Step-by-step explanation:

6,2 is closest to 6

Answer:

0.4

Step-by-step explanation:

The rule you use is x^(-k) = 1/(x^k)

In this case x = 3 and k = 2, so,

3^(-2) = 1/(3^2) = 1/9

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

One way to think of it, is to consider the equation below

3^2*3^x = 1

We can solve for x like this

3^2*3^x = 1

3^(2+x) = 1

3^(2+x) = 3^0

2+x = 0 .... the bases are equal, so the exponents must be equal

x = -2

meaning that

3^2*3^x = 1

updates to

3^2*3^(-2) = 1

Now isolate the 3^(-2)

3^2*3^(-2) = 1

3^(-2) = 1/(3^2)

3^(-2) = 1/9

18 divided by the square root of 9 is equal to 6.

Answer:

6

Step-by-step explanation:

_

3/36 = 18 then dividedby 9 =6

Answer:

Step-by-step explanation:

5x+2-2x+2=3x+4

5x-2x+2+2=3x+4

3x+4=3x+4

equation is satisfied so every value of x will produce the same results on both sides of the equation

Answer:

a) 35km

b) 070 degrees

Step-by-step explanation:

To get full marks look at what I did for question (c)

You have to use a protractor on letter s and make sure the 0 on the protractor is facing the letter (N). Now check where 90 degrees is and draw a line straight by using the ruler then use the compass as u can see in the photo, where (x) point is on the end of the compass is your answer {make sure the compass is 2cm which means its 20km. Also make sure to align the compass on the line you drawn}

Thank you

Answer:

C) Fifteen days

Answer:

C) 15 days

Step-by-step explanation:

To answer this question, we must make an equation, so lets use the variable 'd' equal the number of days a car is being used for:

22d + 100 = 26d + 40

Now, we combine like terms:

22d + 100 = 26d + 40

-22d           -22d

100 = 4d + 40

-40            -40

60 = 4d

/4     /4

d = 15

So, the rental cost will be the same for both car companies after 15 days

Hope this helps :)

(7-9)/(12-10)= 1

Answer:

x= 120°

Step-by-step explanation:

cos(2x)-cos(x)=0

[tex]\Rightarrow 2\cos^2x-\cosx-1=[/tex]0 [as [tex]\cos(2x)=2\cos^2x-1[/tex]]

[tex]\Rightarrow 2\cos^2x-2\cosx +\cosx-1=0[/tex]

[tex]\Rightarrow 2\cos x(\cos x-1) +(\cos x-1)=0[/tex]

[tex]\Rightarrow (\cos x-1)(2\cos x +1)=0[/tex]

[tex]\Rightarrow \cos x-1=0 \;or\; 2\cos x +1=0[/tex]

[tex]\Rightarrow \cos x=1 \;or\; \cos x =-1/2[/tex]

[tex]\Rightarrow x=\cos^{-1}1 \;or\; x =\cos(-1/2)[/tex]

For [tex]x=\cos^{-1}1[/tex] and 0° < x <180°

There is no possible value of x.

For [tex]x =\cos(-1/2)[/tex] and 0° < x <180°

The possible value of x is

x= 120°

Answer:

2 L bottle for 1.69

the unit price for the two liters is cheaper than one for 12 pack

Answer:

a, b, and c

Step-by-step explanation:

all of them are in the form y=mx+b except for c, which does not have a constant slope throughout the entire line, it will be decreasing or negative until 0, and then increasing or positive after 0, so the slopes would not be the same.

Answer:

m<8=150

m<3=150÷3=50

Answer:

G = 14 - 1.75(t)

Where G is the number of gallons of gas remaining;

14 represents the amount of gas in gallons in the full gas tank of the vehicle

t is the number of hours

Step-by-step explanation:

Here, we want to write an equation.

We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left

In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons

So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons

Hence, the equation we want to write will be;

G = 14 - 1.75(t)

Answer:

Profit shall be distributed as :

First seller = $92

Second seller = $72

Third seller = $36

Step-by-step explanation:

Let the first seller be A

Second seller be B

Third seller be C

Let the profit of third price seller C = "x"

Profit of B = 2x

Profit of A = 2x + $20

Total profit received by all of them = $200

$200 = (2x + $20) + (2x) + (x)

$200 = 5x + $20

$180 = 5x

x = $36

Therefore profit for 3rd seller = $36

Profit for second seller = $36 [tex]\times[/tex] 2 = $72

Profit for first seller = $72 + $20 = $92
