Yo sup??

The given equation is y=-7x+9

there is no particular solution of the given equation as many solutions are possible because the given equation represents a line and we know that a line has infinitely many points.

Some points are:

(0,9)

(1,2)

(2,-5)

Hope this helps.

Multiple coordinates work. If you turn this equation into y=mx+b form it is easier. That would be y=-7x+9. A couple coordinates that work are (0,9) (1,2) and (2, -5)

a marina rents party boats for large social gatherings. They charge the following amounts for a 2 hour rental. 10 people for $16
Verdich [7]

Answer:

An equation that represents the data would be y=2.75x+137.50. The y-intercept of the graph is 137.50, which represents the base cost of a boat rental.  The slope of the graph is 2.75, which represents the rate, or cost per person.  If we use this equation to solve for the cost of boat rental for 75 people, we would get a total of $343.75.  A reason the marina might charge more for 75 people could be the need for a second boat and/or additional workers to handle the additional guests.  

Step-by-step explanation:

The problem gives you four sets of ordered pairs: (10, 165); (20, 192.50); (35, 233.75) and (50, 275).  Using these ordered pairs, you can either make a table, or use slope formula with two points to determine the rate of change.  For example, (192.50-165)/(20-10)= 2.75, which represents the slope or cost per person.  To find the y-intercept, or base cost to rent the boat, subtract the cost for 10 people ($27.50) from the $165 rental charge to get $137.50.  In order to find the cost for 75 people, you would plug in 75 for the variable 'x' and solve for 'y', which gives us $343.75.  Since the actual cost is different, we have to assume that there are additional fees associated with a certain number of people.

Luba_88 [7]

Answer: 60 mph.

(486+316+638)/24

The distances given by the table. The time driven is 24 (given by the problem). So the average speed is simply the total distance divided by the time driven.

Amount Financed (m) = $1,860 Number of Payments per year (y) = 12 Number of Payments (n) = 36 Total Interest (c) = $350.00
Luda [366]
Hi there
The formula to find I (ARP)

I=(2yc)/(m×(1+n)
I=(2×12×350)÷(1,860×(1+36))
I=0.1221×100
I=12.21%

Good luck!
