Was there a typo in the possible answers by any chance? B is closest to the possible answer, but only if the division sign was a multiplication sign.
102 <span>÷ 6 = 17
102 </span><span>÷ 17 = 6
17 x 6 = 102
6 x 17 = 102</span>

2/3x - 1/2y = 3

Blizzard [7]

2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18

1/2x + y = 5 |multiply both sides by 2
x + 2y = 10

Answer: B) 4x - 3y = 18 and x + 2y = 10

What’s the degree of x

olga2289 [7]

Answer:
24.23

Step-by-step explanation:
The tan(x) would equal to the opposite side over the adjacent one
So 9/20. To get the degree we need to get the arctan of it, so arctan(9/20) = 24.23

Any REAL help on #16 above??? Can someone check my answer?

babymother [125]

Answer:

The answer to your question is:th first option is correct.

Step-by-step explanation:

Here we have and hyperbola with center (0, 1), and the hyperbola is horizontal because x² is positive.

Equation

y - k = ± $\frac{b}{a} (x - h)$

Process

Find a, b

a² = 9

a = 3

b² = 5

b = √5

h = 0 and k = 1

Substitution

y - 1 = ± $\frac{√5}{3} (x - 0)$

Equation 1

y = $\frac{\sqrt{5} }{3} x + 1$

Equation 2

y = - $\frac{\sqrt{5} }{3} x + 1$
