Answer: The answer is attached in the figure.

Step-by-step explanation: Given are four different graphs and we are to check which one matches with the equation y = 2 - x.

We have the following points on this equation.

(0,2), (1,1), (2,0), etc.

When we try to match these points with the given graphs, the we see that these points does not match with the first, third and fourth graph. The only graph containing these points is second one.

Thus, the second option is correct. Also see the attached figure for the location of the three mentioned points.

In the expression shown p represents a rational number. 4p. what value of p makes the expression equal a number less than 4?

Semenov [28]

C: 7/8
Explanation: Since we want a number that makes 4p less than 4, we need to find a number for p that is less than 1. By looking at each fraction, only 7/8 will render it less than 4

Seascapes rent small fishing boats for a day-long fishing trips. each boat can carry only 1200 lb of people and gear for safety

solmaris [256]

A. We are given that each person weighs 150 lb, each gear per person weighs 10 lb, and a total of 200 pounds of gear for the boat itself.

Since each person only carries one gear, therefore total weight per person in 160 lb (weight of person + weight of gear).

So let us say that x is the number of persons, the inequality equation is:

160 x + 200 ≤ 1200

B. There are three groups that wish to rent the boat.

> Solve the inequality equation when x = 4

160 (4) + 200 ≤ 1200

840 ≤ 1200 (TRUE)

> Solve the inequality equation when x = 5

160 (5) + 200 ≤ 1200

1000 ≤ 1200 (TRUE)

> Solve the inequality equation when x = 8

160 (8) + 200 ≤ 1200

1480 ≤ 1200 (FALSE)

So only the 4 people group and 5 people group can safely run the boat.

C. Find the maximum number of people that may safely use the boat, solve for x:

160 x + 200 ≤ 1200

160 x ≤ 1000

x ≤ 6.25

Therefore the maximum number of people that can safely use the boat is 6 people.

Two different ways to find the difference for 12-3

Gennadij [26K]

For this case we have:

way 1:
Common factor 3 in the expression:
$12-3 = 3 (4-1)

12-3 = 3 (3)

12-3 = 3 (9)$

Way 2:
Write the number 12 as the sum of 4 times 3:
$12-3 = (3 + 3 + 3 + 3) - 3
$
Then, for associative property:
$12-3 = 3 + 3 + 3 + (3 - 3)

12-3 = 3 + 3 + 3 + (0)

12-3 = 3 + 3 + 3

12-3 = 9$
