Answer:

A = 3

B = 8

C = 2

D = 5

Step-by-step explanation:

The language is solved and the four digit code is given by

A = 3

B = 8

C = 2

D = 5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2 + 1 = A

On simplifying the equation , we get

A = 3

Now , 3 + 5 = B

B = 8

And , D + 3 = 8

Subtracting 3 on both sides , we get

D = 5

And , 3 + C = 5

Subtracting 3 on both sides , we get

C = 2

Hence , the four digit code is A = 3 , B = 8 , C = 2 , D = 5

The inverse function is,

⇒ k⁻¹ (x) = -16 (x + 8)

What is Inverse function?

The inverse function returns the  original value for which a function gave the outputs.

Given that;

The function is,

k (x) = -1/16 x - 8

Now, Find the inverse function as;

k (x) = -1/16 x - 8

Substitute k (x) = y,

y = -1/16 x - 8

Find the value of x in terms of y,

y = -1/16 x - 8

y + 8 = -1/16 x

16 ( y + 8 ) = -x

x = -16 ( y + 8 )

Replace x and y,

y = -16 ( x + 8 )

Thus, The inverse function is,

⇒ k⁻¹ (x) = -16 (x + 8)

For the coin: 2 possibilities, either head or tail. So probability of head is 1/2.

For the cube (assuming numbers are 1 to 6): 6 possibilities (1 2 3 4 5 6). We have 3 odd numbers, so probability of odd number is 3/6=1/2.

You want both head and an odd number, so you multiply the 2 probabilities: 1/2×1/2=1/4.

So the answer is 1/4.

You can use a tree to better understand probabilities.

Answer:

6.6

Step-by-step explanation:

The length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.

The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle:

As we know the sum of the triangle is 180°

So I = 180 - 55 - 67 = 58°

Applying sin law to calculate the value of i:

[tex]\rm \frac{i}{sin58} = \frac{k}{sin67}[/tex]

[tex]\rm i = \frac{7.3\times sin 58}{sin67}[/tex]

i = 6.633 units ≈ 6.6 units   (sin58 = 0.848, and sin67 = 0.920)

Thus, the length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.

A. Quadratic trinomial

Step-by-step explanation:

You can easily eliminate B and C because trinomial means there are three terms. B has monomial (one term) and C has binomial (two terms).

Now you have A and D. D is cubic which means the first term (4x²) would have to be cubed (4x³). Quadratic means it is squared.

Answer:

Step-by-step explanation:

Y = mx +b        / Slope intercept form

  mx - y = -b      / Standard form

6m -2 = -b   / Plug in ( 6,2)

-9m -10 = -b / Plug in  ( -9, 10)

 Solve the system of equation for m and b.

 6m -2 = -9m -10  , then   15m = -8      m = -8/15

     b = -6m +2     ,then         b= -6 ( -8/ 15) +2 = 78/15

    -8/15 X -  y = - 78/15

     8X +15y = 78  / Equation of in standard form

Note: This is a different methods of solving this problem. All methods find their roots coming from the basic premises.

Equation of a line in the slope intersect form is

   Y = mx +b

   To convert to standard form of ax + by =c

      Simply move over the parameters

       mx - y = -b        where a = m , and c = -b

      Then we feed coordinates of 2 points in there

       make a 2 equation with 2 unknown( m,b) to

       solve.

Answer: x = 2.

Step-by-step explanation:

By an online search, i found that the question is:

"Given that x satisfies the inequality 20*x > 33,  find the smallest value of x if x is a prime number."

To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.

The prime numbers are:

2, 3, 5, ....

Let's start with the smaller one, x = 2

So we input it in the inequality and get:

20*2 > 33

40 > 33

this is true.

Then we can have x = 2, which is the smaller prime number that satisfies the inequality.
