Select the correct answer. Which equation, when solved, gives 8 for the value of x?

Rus_ich [418]

The 3rd equation, as if you solve for x as shown, you will end up with equation x=8.

$\frac{5}{4}x-\frac{3}{2}x=-4+2$

$\frac{5}{4}x-\frac{6}{4}x=-2$

$-\frac{1}{4}x=-2$

$x=8$

BRAINLIEST!!!!<br><br><br> Identify the equation of the translated graph in general form

RUDIKE [14]

Answer:

Hyperbola:

$x^2-y^2-8x+6y-1=0$

Step-by-step explanation:

the given hyperbola has equation:

$x^2-y^2=8$

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

$(x-4)^2-(y-3)^2=8$

We expand to get:

$x^2-8x+16-(y^2-6y+9)=8$

$x^2-8x+16-y^2+6y-9=8$

$x^2-8x-y^2+6y+7=8$

$x^2-8x-y^2+6y+7-8=0$

$x^2-y^2-8x+6y-1=0$

Svetllana [295]

Answer:

a. Check the attached image

b. The Pr(Y > 2) = ½

c. The mean is 2.4

d. The standard deviation is: 2.72

e. The exact value is 1 because it is certain from the given data that any probability will fall within that range.

Step-by-step explanation:

a. An image showing the step by step solution is attached.

b. P(Y > 2) = P(3) + P(4)

= 2/10 + 3/10 = 5/10 = ½

c. The mean is 2.4

d. The standard deviation is: 2.72

e. Check the attached image for the steps.
