The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
Mekhanik [1.2K]

<em>Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.</em>

<em>So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 530 dollars.</em>

<em>The solution would still clear your concept though.</em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

c(x) = 18x -10

The slope-intercept form of the line equation

We know that the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

so

 c(x) = 18x - 10

comparing with the slope-intercept form of the line equation

  • rate of change = 18
  • c(x) or y represents the cost
  • 'x' represents the number of tickets

Assuming the total cost i.e. c(x) = $530

In order to determine the value of x, set c(x) = 530

i.e.

530 = 18x -10

switch sides

18x - 10 = 530

add 10 to both sides

18x - 10 + 10 = 530 + 10

18x = 540

Divide 18 to both sides

18x/18 = 540/18

x = 30

Therefore, if you can buy x = 30 tickets if you pay 530 dollars.

The automaker of your new car recommends an oil change following the first 5,000 miles and then every 3,000 miles thereafter. If
Jlenok [28]

To determine how many oil changes you will need the first year, you can calculate the number of miles driven the first year and then use that to determine how many groups of 3000 miles you will drive after the first 5000 miles.


1. 52 x 250 = 13000 miles

2. 13000 miles - 5000 miles (1 oil change) = 8000 miles

3. 8000 miles - 3000 miles (1 oil change) - 3000 miles (1 oil change) = 2000 miles


The first year, you will need 3 oil changes.

(1) 4p²q : 10pq²
tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}

i.e. Simplified ratio of 4p²q : 10pq²  is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}

Now, 9 months : 2½ years = \dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = \dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}

Hence, Simplified ratio of  5 m : 600 cm  is 5:6.
