how do i write 3y-9x=24 in function notation
To write an expression in function notation, you must solve it for the dependent variable.
Assuming that you want the expression to be written in the form [tex] y = f(x) [/tex] (i.e., assuming that x is the independent variable), we have to solve the expression for y, which means that we want y to remain alone on the left hand side, and move everything else to the right hand side.
So, first of all, we can add 9x to both sides to get
[tex] 3y = 9x+24 [/tex]
Finally, we divide both sides by 3:
[tex] y = 3x + 8 [/tex]
Four times the difference of a number and five is 24.

Which equation represents the following graph?
A.) Y = 2/3 x + 2
B.) Y = 3/2 x + 2
C.) Y = 2/3 x – 2
D.) Y = -2/3 x + 2
Y intercept (0, 2) so b = 2
Slope = (2 - 0) / (0 + 3) = 2/3
Equation y = mx + b
In this case slope m = 2/3 and y intercept = b = 2
So equation y = 2/3 x + 2
Answer
A.) Y = 2/3 x + 2

The problem is about solving a simple algebraic equation. The given condition can be put into an equation and solved step by step. The number that meets the condition is 4.
Explanation:The subject of this problem is algebra. We need to find a number that satisfies the given condition. If we define the unknown number as 'x', the given statement can be translated into the following algebraic equation: 1 + 3x = 2x + 5.
To find the number, we solve this equation step by step. First, we can rearrange the equation by subtracting 2x from both sides, which gives us: 1 + x = 5. Then, subtracting 1 from both sides, we have: x = 4.
So, the number that satisfies the given condition is 4.

The time it takes an excursion boat to travel 36 miles downstream is the same as the time it takes the boat to travel 12 miles upstream. If the stream is 4 miles per hour, which of the following is the speed of the boat in still water.
The speed of the boat in still water is 8 miles per hour.
Explanation:To find the speed of the boat in still water, we can use the formula:
Speed of the boat in still water = (speed downstream + speed upstream) / 2
Given that it takes the same amount of time for the boat to travel 36 miles downstream and 12 miles upstream, we can set up the following equation:
36 / (v + 4) = 12 / (v - 4)
Where v is the speed of the boat in still water. Cross multiplying and solving the equation, we get:
36(v - 4) = 12(v + 4)
36v - 144 = 12v + 48
24v = 192
v = 8
Therefore, the speed of the boat in still water is 8 miles per hour.

A department store sold 34 shirts one day. All short-sleeved shirts cost $11.00 each and all long-sleeved shirts cost $21.00 each. Total receipts for the day were $514.00. How many of each kind of shirt were sold?
The department store sold 20 short-sleeved shirts and 14 long-sleeved shirts. Calculations were made by setting up a system of equations and solving for the variables representing the number of shirts sold.
To solve how many short-sleeved and long-sleeved shirts were sold given the total sales and price per shirt, we can set up a system of equations. Let x represent the number of short-sleeved shirts and y represent the number of long-sleeved shirts. We have two equations: x + y = 34 (since a total of 34 shirts were sold) and 11x + 21y = 514 (representing the total sales from the shirts).
First, we can solve for x in terms of y from the first equation: x = 34 - y. Substituting this expression for x into the second equation gives us 11(34 - y) + 21y = 514. Simplifying this, we get 374 + 10y = 514, which simplifies down to y = 14.
Substituting y = 14 back into the original first equation x = 34 - y, we find that x = 34 - 14, so x = 20. Therefore, the store sold 20 short-sleeved shirts and 14 long-sleeved shirts.

How many weeks of flea treatment would Jim’s dog get from one package if each treatment only lasted 3 weeks In a normal year when a flea treatment last 4 weeks how many more weeks of treatment would Jim’s dog get from one package. Each flea treatment usually last for about 4 weeks but one year the fleas were especially bad Jim’s dog needed to be treated for fleas every 3 weeks until the weather cooled off
Solution
Number of weeks in a year = 52 weeks
If in a normal year when each package of flea treatment lasts for 4 weeks, then in a year there Jim's dog will have to be treated for
[tex]\frac{52}{4} =13 times[/tex]
Where as, when the fleas are bad in a year, the treatment lasts for only 3 weeks.
Then in a year Jim's dog would get
[tex]\frac{52}{3} =17 times[/tex]
So Jim's dog will get 17- 13 =4 treatments more.
4 treatments that are made in 3 weeks each will be 4×3 =12 weeks more treatment
The Number treatments is the ratio of the number of weeks in a year and the number weeks per treatment. Hence, Jim's dog would get 4 more treatments due to the bad weather.
Number of weeks in a year = 52
Period of flea treatment due to weather = 3 weeks Normal duration of flea treatment = 4 weeksThe number of flea treatment he'll get in a year can be calculated thus :
Normal weather = 52 / 3 = 17. 333 = 17 treatments
Bad weather = 52 / 4 = 13 treatments
Difference in treatment = 17 - 13 = 4
Therefore, as a result of the bad weather, Jim's dog would get 4 more treatments than during normal weather.

When a number is raised to the power of 2, it is squared. This means the number is multiplied by itself once.
Explanation:When a number is raised to the power of 2, it is squared. Squaring a number means multiplying it by itself. For example, if you have the number 4 and you square it (raise it to the power of 2), you would multiply 4 by 4, which equals 16. Therefore, 4 squared (or 4 to the power of 2) equals 16.

[tex]12(m + 3x) = 18(x - 3m)[/tex]
To solve the equation 12(m + 3x) = 18(x - 3m), we can start by distributing the coefficients and collecting like terms. Finally, m = -3x/11.
Explanation:The given equation is 12(m + 3x) = 18(x - 3m).
To solve this equation, we need to distribute the 12 and 18 coefficients to the terms inside the parentheses. This gives us 12m + 36x = 18x - 54m. Next, we collect like terms on each side of the equation. Combining the 'm' terms, we get 12m + 54m = 18x - 36x. Simplifying both sides further, we have 66m = -18x.To isolate 'm', we divide both sides of the equation by 66, resulting in m = -18x/66. This can be simplified to m = -3x/11.Therefore, the solution to the equation is m = -3x/11.

You and a friend buy two fruit smoothies and leave a tip. You split the total and your half cokes to 3.60. What percent tip (in decimal form) did you and your friend leave if the fruit smoothies cost $3 each?
If you bought a $3 smoothie and your total (with tip) is $3.60, you have to divide 3.6/3. You get 1.2, which means you left a 20% tip, which would be .2 in decimal form.
To find the percent tip, divide the tip amount by the total cost and multiply by 100.
Explanation:To find the percent tip, we need to first calculate the total cost of the smoothies and the tip. Since the smoothies cost $3 each, the total cost of the smoothies is $3 * 2 = $6. Let's assume the tip amount is x dollars. The split total (including the tip) is $3.60, which is equal to half of the total cost plus the tip: $3 + $3 + x = $6 + x. Solving this equation, we can find the value of x:
$6 + x = $3.60 * 2$6 + x = $7.20x = $7.20 - $6 = $1.20The tip amount is $1.20. To find the percent tip in decimal form, we divide the tip amount by the total cost and multiply by 100: $1.20 / $6 * 100 = 20%. Therefore, you and your friend left a 20% tip.
