8 ) 712

8 goes into 71 8 times; the product of 8 and 8 is 64.

Subtracting this 64 from 71, we get 7, to which we append 2: 8 ) 72.

8 divides evenly into 72: 9.

Thus, the desired quotient is 89.

Find the value of x. -2(6x - 3) = 27

SOVA2 [1]

Answer:

x = -7/4

Step-by-step Solution:

Let's simplify the equation to find the value of x.

-2(6x - 3) = 27

[Simplify the Distributive property]

=> -12x + 6 = 27

[Subtract 6 both sides]

=> -12x = 27 - 6

[Solve the RHS]

=> -12x = 21

[Divide -12 both sides to isolate the variable]

=> x = -21/12

[Simplify the fraction]

=> x = -7/4

Hence, the value of x is -7/4.

Write the equation of a hyperbola centered at the origin with x-intercepts +/- 4 and foci of +/-2(sqrt5)

Xelga [282]

Answer:

$\frac{x^2}{16}-\frac{b^2}{4}=1$

Step-by-step explanation:

A hyperbola is the locus of a point such that its distance from a point to two points (known as foci) is a positive constant.

The standard equation of a hyperbola centered at the origin with transverse on the x axis is given as:

$\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$

The coordinates of the foci is at (±c, 0), where c² = a² + b²

Given that a hyperbola centered at the origin with x-intercepts +/- 4 and foci of +/-2√5. Since the x intercept is ±4, this means that at y = 0, x = 4. Substituting in the standard equation:

$\frac{x^2}{a^2}-\frac{y^2}{b^2}=1\\\frac{4^2}{a^2}-\frac{0}{b^2} =1\\\frac{4^2}{a^2}=1\\ a^2=16\\a=\sqrt{16}=4\\ a=4$

The foci c is at +/-2√5, using c² = a² + b²:

$c^2=a^2+b^2\\(2\sqrt{5} )^2=4^2+b^2\\20 = 16 + b^2\\b^2=20-16\\b^2=4\\b=\sqrt{4}=2\\ b=2$

Substituting the value of a and b to get the equation of the hyperbola:

$\frac{x^2}{a^2}-\frac{y^2}{b^2}=1\\\\\frac{x^2}{16}-\frac{b^2}{4}=1$

I really need help with this

BabaBlast [244]

Answer:

A (-4, 1)
B (2, 5)

Step-by-step explanation:

The current endpoints are ...

V = (-9, 2)

W = (-3, 6)

Put each of these in the translation formula to see where the image points are.

(x, y) ⇒ (x+5, y-1)

(-9, 2) ⇒ (-9+5), 2-1) = (-4, 1) . . . . point V ⇒ V'

(-3, 6) ⇒ (-3+5, 6-1) = (2, 5) . . . . . point W ⇒ W'

The new end points are (-4, 1) and (2, 5), matching choices A and B.
