Please give me the correct answer.​

Answer:

(6,9)

Step-by-step explanation:

Y=2/3x+5

Y=x+3

2/4x + 5 = x + 3

Solve the equation

x=6

Substitute the value of x

y=6+3

Solve the equation again.

Now we know y=9

(x,y) = (6,9)

Check the solution

9=2/3 x 6 + 5

9=6+3

Simplify

The value of (a) and (b) for the hyperbola are [tex]\sqrt 3[/tex] and 2

The equation of the hyperbola is given as:

[tex]\frac{y^2}{b^2} - \frac{x^2}{a^2} = 1[/tex]

The curve of the graph passes through points (0,2) and (-4,3).

So, we have:

[tex]\frac{2^2}{b^2} - \frac{0^2}{a^2} = 1[/tex] and [tex]\frac{(-4)^2}{b^2} - \frac{3^2}{a^2} = 1[/tex]

[tex]\frac{2^2}{b^2} - \frac{0^2}{a^2} = 1[/tex] becomes

[tex]\frac{4}{b^2} = 1[/tex]

Cross multiply

[tex]b^2 = 4[/tex]

Take positive square root of both sides

[tex]b = 2[/tex]

[tex]\frac{(-4)^2}{b^2} - \frac{3^2}{a^2} = 1[/tex] becomes

[tex]\frac{(-4)^2}{2^2} - \frac{3^2}{a^2} = 1[/tex]

[tex]\frac{(-4)^2}{4} - \frac{9}{a^2} = 1[/tex]

[tex]4 - \frac{9}{a^2} = 1[/tex]

Collect like terms

[tex]- \frac{9}{a^2} = -3[/tex]

Cross multiply

[tex]-3a^2 = -9[/tex]

Divide both sides by -3

[tex]a^2 = 3[/tex]

Take square roots of both sides

[tex]a = \sqrt 3[/tex]

Hence, the value of (a) and (b) for the hyperbola are [tex]\sqrt 3[/tex] and 2

Answer:

Step-by-step explanation:

Answer:

By applying law of conservation of mass.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.

This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

For the given reaction, the balanced chemical equation follows:

4Na1+Pb(SO4)__Pb14+2Na2SO4

On reactant side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

On product side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

Hence, the balanced chemical equation is written above.

Answer:

Step-by-step explanation:

Derive an equation to represent the cost of using each ride.

Sal's Car Rides:

Using 2 pairs of values from the table, (0, 40) and (20, 80), find the slope, m (fee per mile).

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{80 - 40}{20 - 0} = \frac{40}{20} = 2 [/tex]

The y-intercept, b, is the one-time fee for fuel. This is the value of the cost ($) when number of miles traveled is 0.

Thus, b = 40.

Substitute m = 2, and b = 40 into [tex] y = mx + b [/tex].

Equation for the total cost for Sal's Car Rides would be:

[tex] y = 2x + 40 [/tex].

Find the total cost to be charged if a customer requires the a car service for 80 miles if he chooses Sal's Car Rides.

Simply substitute x = 80 in [tex] y = 2x + 40 [/tex].

[tex] y = 2(80) + 40 = 200 [/tex]

The customer would pay $200.

Ray's Limo:

The equation that represents the total cost (y) to be charged for number of miles (x), given that $2.50 is charged per mile plus a one-time fee of $25 for fuel, would be:

[tex] y = 2.5x + 25 [/tex].

If a customer uses Ray's Limo services for 80 miles, the cost charged would be:

Substitute x = 80 in [tex] y = 2.5x + 25 [/tex].

Thus:

[tex] y = 2.5(80) + 25 = 225 [/tex].

The fee the customer would pay = $225 for using Ray's Limo services.

Therefore, if the customer takes Sal's Car Rides instead of Ray's Limo, he would save, $225 - $200 = $25.

The customer would save $25.

Answer:

X=7.5 y=-1

Step-by-step explanation:

[tex]2x + 7y = 8 \\ 2x + y = 14[/tex]

I multiplied the equation with - 1 to than I sum it with the second one to get rid of x

[tex] - 6y = 6 \\ y = - 1[/tex]

Now you put Y in on of the equation and you get x.

[tex]2x - 1 = 14 \\ 2x = 15 \\ x = 7.5[/tex]

Answer:

Options (3), (4) and (6)

Step-by-step explanation:

Coordinates of the vertices of the given rectangle are,

A(1, 5), B(3, 2), C(-3, -2) and D(-5, 1)

When rectangle ABCD is dilated by a scale factor of 2 about the origin,

Rule to be followed for the dilation,

(x, y) → (2x, 2y)

Therefore, image of the rectangle ABCD will be,

A(1, 5) → A'(2, 10)

B(3, 2) → B'(6, 4)

C(-3, -2) → C'(-6, -4)

D(-5, 1) → D'(-10, 2)

- Hence point B' is located at (6, 4).

- Rectangle ABCD and A'B'C'D' are similar as all the angles of image will be same as the pre-image after rigid transformation (dilation).

- Let the equation of the line B'C' is,

 y = mx + b

 Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                  =  [tex]\frac{4-2}{6-3}[/tex]

                  = [tex]\frac{2}{3}[/tex]

 Since B'C' will pass through origin, y-intercept will be zero.

 Therefore, equation of B'C' will be,

  y = [tex]\frac{2}{3}x[/tex]

 Options (3), (4) and (6) are the correct options.

well im confused but dont you have to find the prime too

Step-by-step explanation:

Answer:

26 5/12

Step-by-step explanation:

n − 2/3 = 25 3/4                            Add 2/3 to both sides

n - 2/3 + 2/3 = 25 3/4 + 2/3         Combine

n = 25 3/4 + 2/3

Work with the fractions

3/4 + 2/3                                      The lowest common denominator is 12

(3*3)/(3*4) = 9 / 12

(2*4)/(3*4) = 8/ 12

9/12 + 8/12 = 17/12 = 1 5/12

Now you need to add 1 to 25

1 + 25 = 26

And add the fraction 5/12

The answer is 26 5/12
