What Is Y? (look At The Picture I Attached, Thank You!)

Answers

Answer 1

Answer:

[tex]y = \frac{19}{5} [/tex]

Step-by-step explanation:

[tex] \frac{2y - 4}{y + 7} = \frac{1}{3} [/tex]

or, 3(2y-4) = 1(y+7)

or, 6y-12 = y +7

or, 6y-y = 7+12

or, 5y = 19

or, y = 19/5

Answer 2

Answer:

y=19/5

b). Kirchoff has more money than Maxi. If Kirchoff gave Maxi $20, they would have the
same amount. While it Maxi gave Kirchoff $22, Kirchoff would then have twice as much as
Maxi. How much does each one actually have?​

Answers

Answer:

k = 146

m= 106

Kirchoff has $146

Maxi has $106

Step-by-step explanation:

For the purpose of the equations, I’ll call Kirchoff and Maxi a and b respectively.

a - 20 = b + 20 (equation 1)

2(b - 22) = a + 22 (equation 2)

We can juggle those around for

a = b +40 (equation 1r (re-arranged)) and

2b - 44 = a + 22 so 2b - 66 = a (equation 2r (rearranged))

The equations are now:

a = b + 40 (new equation 1) and

a = 2b - 66 (new equation 2)

Substitute from new equation 1 to new equation 2:

b + 40 = 2b - 66 so 40 = b - 66 making b = 106.

Plug b = 106 into new equations 1 and 2 for:

a = 106 + 40 (new equation 1) and

a = 212 - 66 (new equation 2)

This gives a = 146 and b = 106

TEST: There’s a gap of $40, so giving $20 from a to b makes them equal.

SECOND TEST: Subtracting $22 from b makes it $84 and giving that sum to a makes it $168, twice as much. The tests work.

Kirchoff has $146 and Maxi has $106.

If you roll a number cube 60 times and use the results to calculate the experimental probability of rolling a 1, the experimental probability of rolling a 1 will _____ be less than the theoretical probability of rolling a 1.

Answers

Answer:

sometimes

Step-by-step explanation:

Theoretical probability is fixed/remains the same because it is based on theory which is calculated, while the experimental probability is based on data that is gained from actually doing it. According to the law of large numbers, the average experimental probability always approaches the theoretical probability.

Answer:

  y = -3x - 23

Step-by-step explanation:

When a transversal of the two lines is constructed, the alternate interior angles formed by the transversal are congruent. This means line m and n are parallel to each other so their slope will be the same.

Given:

  line m:   y = -3x + 8                 <======= slope is -3

line n going through point (-4, -11) with same slope as line m:

  y = mx + b

  (-11) = -3(-4) + b

  -11 = 12 + b

  b = -23                                    <===== y-intercept of line n

Use the above slope and y-intercept to form equation of line n:

  y = mx + b

  y = -3x - 23

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial

Answers

Answer:

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

[tex]x(3x-1)(2x+5)[/tex]

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

[tex]=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)[/tex]

Now multiplying with x

[tex]= 6x^3+13x^2-5x[/tex]

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3
