Answer: 15 packages with 4 pens and 3 packs of paper each

Step-by-step explanation:

Answer:

y = m x + b      standard equation for straight line

-2 = 3 *2 + b    to satisfy above equation

b = -8

therefore

y = 3 x - 8

if x = 2 then y = -2

Answer:

Step-by-step explanation:

You could graph it. I'll do that at the bottom. What you need is a value that is - on either 2 or 3 and a plus on the other one.

y=12*2^3 - 32x^2 + 17

y = 12 * 8 - 32*2^2 + 17

y = 96 - 128 + 17

y = -15

Now when x = 3 should give you something above the x axis

y = 12*3^3 - 32*9 + 17

y = 324 - 288 + 17

y = 53

What this indicates is that somewhere between 2 and 3 the graph crosses the x axis. The graph should indication that.

Step-by-step explanation: ,..

The number of times an action is performed between every other person in a group can be calculated using the relation [tex] \frac{n(n - 1)} {2}[/tex] which is 136 times

Using the formular ;

[tex] \frac{n(n - 1)} {2} = \frac{17(17 - 1)} {2}[/tex]

[tex] \frac{17(17 - 1)} {2} = \frac{17 \times 16} {2}[/tex]

[tex] \frac{17 \times 16} {2} = \frac{272}{2} = 136 [/tex]

Answer:

33

Step-by-step explanation:

1. Let's solve for g(3)

Step 1: Plug in the value of x.

Step 2: Simplify.

2. Let's solve for g(-8)

Step 1: Plug in the value of x.

Step 2: Simplify.

3. Now, let's subtract g(-8) from g(3).

Therefore, the answer is 33.

Answer:

33

Step-by-step explanation:

g(x) = 3x - 2

g(3) = when x of g(x) function is 3.

g(3) = 3(3) - 2

g(3) = 9 - 2

g(3) = 7

g(-8) = 3(-8) - 2

g(-8) = -24 - 2

g(-8) = -26

g(3) - g(-8)

7 - (-26) = 33

Answer:

730

Step-by-step explanation:

Because when you add 365 and 365 together, you get 730

The mathematical answer to 365 x 2 is 1825.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

The mathematical expression; 365*5

Now,

=365*5

=1825

Therefore, by algebra multiplication will be 1825.

Answer:

Angle B is 52 degrees

Step-by-step explanation:

The outer angle 112 adds up with the inner angle to make 180. So angle C is 68. All the angles should add up to 180, so add them all together.

68+4y+3y+7 = 180

75+7y = 180

7y = 105

y = 15

To double-check this, plug 15 into y and add up all the angles, it should add up to 180.

3(15)+7 = 52

4(15) = 60

68+60+52 = 180

Answer:

  (A) -4 and -2

Step-by-step explanation:

The constant in the function tells you f(0) = 5.

You know that the positive leading coefficient means the value of f(x) will be negative for x-values smaller than some number. The offered answer choices indicate the value x = -4 is a lower bound on the value of c. So, -4 < c < 0, for sure.

To further refine the interval, you would need to know f(-2) and/or f(-1).

  f(-2) = (-2)³ -2(-2) +5 = -8 +4 +5 = 1

Then -4 < c < -2.

Answer:

Angle 5 should be 60

Step-by-step explanation:

Angle 2 and angle 4 are the same because they are Corresponding Angles. so if the lines m and n equal 180 then you subtract 120 from 180 and you get 60 so 5 ,7, 1 and 3 are 60 degrees
