Answer:

second pack

Step-by-step explanation:

1.25÷4= 0.31 so for the first pack 1 pencil cost $0.31

2.50×20%= 0.5 so its ¢50 off. 2.50-0.50= 2. 2÷8= 0.25. so for the second pack 1 pencil costs $0.25 which is lower than the 1st pack.

I hope it wasn't too confusing

Answer:

  yes

Step-by-step explanation:

Put the numbers into the inequality and see if it is true.

Given x = 20, y = 18, ...

  3x + 2y = 3(20) +2(18) = 60 +36 = 96 ≥ 93 . . . . true

Answer:

1

Step-by-step explanation:

First, you should put the equation in slope intercept form (y = mx + b), where m is the slope.  A parallel line will have the same slope so if 1x is your slope for the first equation, 1 should also be the slope for the 2nd equation

Answer:

Part A: The origin would be (0, 0)

Part B:

(-1, 1)  starting from the origin (0,0), would move left 1 on the x-axis  then you would move up 1 on the y-axis

(1, -1.5)  starting from the origin (0,0), you would move to the right 1 on the x-axis, then you would move down 1.5 on the y-axis

(2, 1/4) starting from the origin (0,0), you would move to the right 2 on the x-axis, then you would move up 1/4 (.25).

a) The origin would be (0, 0).

Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x axis (horizontal) and y axis (Verticle) are the two axes that make up a coordinate plane.

Given:

a) The origin would be (0, 0).

b) First, (-1, 1) move left 1 on the x-axis then you would move up 1 on the y-axis

Second, (1, -1.5) move to the right 1 on the x-axis, then move down 1.5 on the y-axis

Third, (2, 1/4) move to the right 2 on the x-axis, then move up 1/4 (.25).

Therefore, using the models, we can conclude that the answer is x = 3.

Answer:

x = 3

Step-by-step explanation:

2x - 3y - z = 7 (equation 1)

3x + 5y - 3z = -2 (equation 2)

4x – y + 2z = 17 (equation 3)

(1) * 3 : 6x - 9y - 3z = 21 (1)'

(1)' - (2) :  3x - 14 y = 23 (equation 4)

(1) * 2 : 4x - 6y - 2z = 14 (1)"

(1)" + (3) : 8x - 7y = 31 (equation 5)

(5)*2 : 16x - 14y = 62 (5)'

(5)' - (4) : 13x = 39

              x = 3

So thus, x = 3 in this system of equations, you can plug x back into equation 4 or 5 to find y and then plug x and y back into equations 1, 2, or 3 to find z

Answer:

Step-by-step explanation:

which questions you are telling there is no question to answer you!!

Answer:

In two or more complete sentences, explain how to use ordered pairs of points in f(x) = 2x + 5 and to determine if f(x) and g(x) are inverses of each other?

It is very difficult to know because you did not include the function g(x), you only gave us f(x).

Given two lists of ordered pairs [x,f(x)] and [x,g(x)]. If for every ordered pair on the f(x) list the reverse is on the g(x) list the functions are inverses.

f(0) = 5 so for (0,5) on the f(x) list then (5,0) must be on the g(x) list

f(1) = 7 so for (1,7) on the f(x) list then (7,1) must be on the g(x) list

f(2) = 9 so for (2,9) on the f(x) list then (9,2) must be on the g(x) list

So even though you didn’t list g(x), g(x) = (x/2) - 5/2

It is false both nations will benefit if the terms of trade are  1 peanut = 3 corn.

The comparative advantage refers to the ability of one company or nation to produce something at a lower cost. In this case, the U.S. can produce peanuts at a lower cost than Canada.

No, due to their differences in the amounts of units produced and their comparative advantage both nations will not benefit from this trade.
