Answer:

The y-intercept is -7

Step-by-step explanation:

Divide both sides by 2, to isolate the y -variable. Then you get

y = -5/2x - 7

For circle H, JN = x, NK = 2, LN = 3, and NM = 6. Solve for x.
Advocard [28]

Answer:

The value of x is 9 ⇒ C

Step-by-step explanation:

In a circle, if two chords intersected at a point inside it there are four segments created, two in each cord, the products of the lengths of the line segments on each chord are equal.

<em>Let us use this rule to solve the question</em>

In circle H

∵ Jk and LM are chords intersected at point N inside the circle

∴ The created segments are JN, Nk, and LN, NM

→ By using the rule above

∴ JN × NK = LN × NM

∵ JN = x and NK = 2

∵ LN = 3 and NM = 6

→ Substitute these values in the equation above

∴ x × 2 = 3 × 6

∴ 2x = 18

→ Divide both sides by 2 to find x

∴ \frac{2x}{2}=\frac{18}{2}

∴ x = 9

∴ The value of x is 9

Answer:

4 sqrt(5)

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

5

83 +12 sqrt(35)

Step-by-step explanation:

1.   4 sqrt(6)

 --------------------

sqrt(30)

Multiply the top and bottom by sqrt(30) to rationalize the denominator

4 sqrt(6) *sqrt(30)

 --------------------

sqrt(30)*sqrt(30)

4 sqrt(180)

 --------------------

30

Simplify

2 sqrt(36 *5)

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

15

We know that sqrt(ab) = sqrt(a) sqrt(b)

2 sqrt(36)sqrt(5)

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

15

2 *6*sqrt(5)

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

15

Simplify

2 * 2 sqrt(5)

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

5

4 sqrt(5)

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

5

2. (2 sqrt(5) + 3 sqrt(7))^2

(2 sqrt(5) + 3 sqrt(7)) (2 sqrt(5) + 3 sqrt(7))

FOIL

first 2sqrt(5)*2sqrt(5)=4*5=20

outer 2 sqrt(5) * 3 sqrt(7) = 6 sqrt(35)

inner  3 sqrt(7) *2 sqrt(5) = 6 sqrt(35)

last 3sqrt(7) 3sqrt(7) = 9*7 = 63

Add them together = 20 + 6 sqrt(35)+ 6 sqrt(35) +63 = 83 +12 sqrt(35)
