y is inversely proportional to x given that y=-50 when x=3 find y when x=10

Answer:

(8, 6 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 34 → (1)

3x + 2y = 36 → (2)

Multiplying (1) by 3 and (2) by - 2, then adding will eliminate the x- term

6x + 9y = 102 → (3)

- 6x - 4y = - 72 → (4)

Add (3) and (4) term by term to eliminate x, that is

5y = 30 ( divide both sides by 5 )

y = 6

Substitute y = 6 into either of the 2 equations and solve for y

Substituting into (1)

2x + 3(6) = 34

2x + 18 = 34 ( subtract 18 from both sides )

2x = 16 ( divide both sides by 2 )

x = 8

solution is (8, 6 )

Answer:

[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]

[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Step-by-step explanation:

Given equations:

[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]

A. x² + 19 = 10

Step 1: Subtract 19 from both sides.

[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]

Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]

Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.

Step 2: Take the square root of both sides (positive and negative roots).

[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]

Step 3: Separate the solutions.

[tex]\implies x_1=-3i,\ x_2 =3i[/tex]

----------------------------------------------------------------------------------------------------------------

B. 4x² + 3 = 43

Step 1: Subtract 43 from both sides.

[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]

Step 2: Divide both sides by 4.

[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]

Step 3: Take the square root of both sides (positive and negative roots).

[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]

Step 4: Separate the solutions.

[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

FFM would be included in the compound event with more than one female.

Option (C) is the correct answer.

"A compound event is is an event which involves the probability of two or more outcomes."

"In probability, an outcome of an experiment are the all possible results. "

For given question,

Sample space:

S = {MMM, MMF, MFM, MFF, FMM, FMF, FFM, FFF}

Kaia’s mom is having triplets each baby could be either male or female.

We need to find the outcome that would be included more than one female.

So, the possible outcomes are: {MFF, FMF, FFM, FFF}

From given option FFM is the correct answer.

Answer:

True ; false ; False ; true

Step-by-step explanation:

Equation 1:

7 20 + □ = 19 20

19 / 20 - 7/20

(19 - 7) / 20

12/ 20 = 3/5

Equation 2:

□ + 3 10 = 3 15

3/5 + 3/10

(6 + 3) / 10 = 9/10

Equation 3:

1 2 + 2 3 = □

1/ 2 + 2/3

(3 + 4) / 6

7 / 6

Equation 4:

1 10 + 1 2 = □

1/10 + 1/2

(1 + 5) / 10

6 / 10 = 3/5

Answer:

Axis of symmetry is 0

vertex is 1

Step-by-step explanation:

(A ∩ B)' is the complement of A ∩ B, or the set of all elements in the universal set U that do not belong to A ∩ B.

A ∩ B is the intersection of A and B, or the set of all elements common to both A and B.

We have

A = {q, s, u, w, y}

B = {q, s, y, z}

so that

A ∩ B = {q, s, y}

Then

(A ∩ B)' = {r, t, u, v, w, x, z}

which makes (c) the answer.

Hi there!

When x is equal to 5, 4x and 15+x have the same value because 4*5= 20 and 15+5 = 20.

4x and 15+x are not equivalent expressions because they cannot be simplified to create the same expression nor will they produce the same answer every time.

Inequalities

Solve the inequality:

[tex]x^2-x\ge 6[/tex]

Subtracting 6:

[tex]x^2-x-6\ge 0[/tex]

Factoring:

(x-3)(x+2) ≥ 0

We have a product that must be greater or equal to 0. This can only happen if:

x - 3 ≥ 0  and x + 2 ≥ 0

Or:

x - 3 ≤ 0  and  x + 2 ≤ 0

The first couple of conditions yields to:

x ≥ 3 and x ≥ -2

Which lead to the solution

x ≥ 3       [1]

The second couple of conditions yields to:

x ≤ 3 and x ≤ -2

Which lead to the solution

x ≤ -2        [2]
