A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes.
Paladinen [302]

Answer:

Answer:

\{ {{20x+30y=280} \atop {y=4x}} .{

y=4x

20x+30y=280

.

Where xx is the number of small boxes sent and yy is the number of large boxes sent.

Step-by-step explanation:

Let be xx the number of small boxes sent and yy the number of large boxes sent.

Since each small box can hold 20 books (20x20x ), each large box can hold 30 books (30y30y )and altogether can hold a total of 280 books, we can write the following equation to represent this:

20x+30y=28020x+30y=280

According to the information provided in the exercise, there were 4 times as many large boxes sent as small boxes. This can be represented with this equation:

y=4xy=4x

Therefore, the system of equation that be used to determine the number of small boxes sent and the number of large boxes sent, is:

\{ {{20x+30y=280} \atop {y=4x}} .{

y=4x

20x+30y=280

Rabbits in a colony breed and give birth to baby rabbits. What model best describes the total number of rabbits in the colony ov
zimovet [89]

Answer: A) Exponential Function

Step-by-step explanation:

Hi, an exponential function describes best the total number of rabbits in the colony over time, because the population tends to multiply by a specific rate over time.

An exponential function can be described as a growth function, for example in the form:

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form)  

t= years  

A = population after t years

Can I get help on this please? You will be marked Brainliest and 5 ⭐️ <br> Thank you!!!

Answer:

y = 50x

Step-by-step explanation:

the equation for this is y = 50x because for every 50 units we go up by on the graph we go 1 unit to the right so:

slope-intercept form: y = mx + b   where m is the slope and b is the y-intercept. Our y-intercept is 0 because that is where our line intersects the y-axis and because it is 0 we do not need to put it in the equation.

y = 50x
