Answer:
y = 85x + 55
Step-by-step explanation:
If we use the given prices as coordinates we will get the coordinates (2, 225) and (5, 480) and if we use the rise over run which in this case is 255/3 then we get the slope which is $85 and now we plug what we know into y = mx + b. we now have the equation 225 = (85)2 + b which can be simplified to 55 = b and now we can create the equation y = 85x + 55.

Answer:
$20 x 37.5 x 52, or $39,000
Step-by-step explanation:
for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More
<h3>For how many flyers is the cost at A-Plus Printers less than the cost at Print-and-More?</h3>
A-Plus Printers charges $26 plus $0.12 per flyer, so if you print x flyers, the total cost is:
f(x) = $26 + $0.12*x
For Print-and-More, they charge only $0.25 per flyer, so here the equation is:
g(x) = $0.25*x
Here we need to see for which value of x the costs are the same:
f(x) = g(x)
$26 + $0.12*x = $0.25*x
Now we can solve that linear equation for x:
$26 = $0.25*x - $0.12*x
$26 = $0.13*x
$26/$0.13 = 200
This means that for 200 flyers, the cost is the same in both places, then for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More.

Based on the calculations, the slowest rate is equal to 4 gallons per minute.
<u>Given the following data:</u>
- Distance from shore = 12 km.
- In-rate = 3 gallons per minute.
- Rowing rate = 24 km per hour.
<h3>How to calculate the slowest rate.</h3>
Let's assume the boat would sink if it takes in more than 20 gallons of water.
<u>Conversion:</u>
- 24 km/h to km/min =
= 0.4 km/min.
Translating the word problem into an algebraic expression, we have;

Therefore, the slowest rate is equal to 4 gallons per minute.

Answer:
=760 ft
Step-by-step explanation:
h=16t^2+126t
Let t=4
h = 16 (4)^2 +126(4)
h = 16*16 +126(4)
=256+504
=760 ft
