So line b is (0,0) and (4, -3/2)

slope = m = y2-y1/ x2-x1

= -3/2 - 0 / (4-0 )= -3/8

now using point slope y-y1=m(x-x1)

m=-3/8 and point is (0,0) to make it easier
y-0 = -3/8 (x-0)
y=-3/8x

so we have the first line done, now another line is parallel to line b which means they have the same slope

line 2 has slope = m = -3/8
and point (0,-7)

using point slope again y-y1=m(x-x1)

y- (-7) = (-3/8) (x-0)

y=(-3/8)x -7

hope that helps and is right

TO TRANSMIT INFORMATION ON THE INTERNET, LARGE FILES ARE BROKEN INTO PACKETS OF SMALLER SIZES. EACH PACKET HAS 1,500 BYTES OF IN

borishaifa [10]

Answer:

A. It would be needed 20 packets to transmit 30,000 bytes of information.

B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Size of each packet of information = 1,500 bytes

Number of packets = P

Number of bytes of information = B

2. Let's answer the questions:

A. How many packets would be needed to transmit 30,000 bytes of information?

P = 30,000 ÷ 1,500

P = 20

It would be needed 20 packets to transmit 30,000 bytes of information

B. How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

$\dfrac{1}{4}x + \dfrac{1}{2} = \dfrac{1}{4}x- \dfrac{1}{2}$

$\text{Cancel 1/4x on both sides}$

$\dfrac{1}{2}=-\dfrac{1}{2}$

$\text{There is no solution}$

In 2010, the population of a city was 241,000. From 2010 to 2015, the population grew by 5%. From 2015 to 2020, it fell by 4%. T

lawyer [7]

Answer:

242, 900 people

Step-by-step explanation:

To begin, it says that the population grew by 5%.

(241000)(1.00 + 0.05) = population of the city in 2015

(241000)(1.05) = 253050

253050 is the population of the city in 2015. From 2015 to 2020 it fell four percent.

(253050)(1.00 - 0.04) = population of the city in 2020

(253050)(0.96) = 242928

242928 is the exact population of the city. However, it says to round to the nearest hundred. Since 28 is less than 50, then it would round down to 900.

Therefore, the answer would be 242, 900 people.
