When y varies inversely with x that means mathematically

  y = \frac{k}{x}

  •  k ⇒ is the <u>proportional constant</u> that we need to find

We know for one, that when y = 68 and x = 1/17, that means

  68 = \frac{k}{\frac{1}{17} } \\68 = 17k\\k = 4

Therefore we get the equation of the relationship between y and x as

  ⇒ y = \frac{4}{x}

So when y = 16, then

 16 = \frac{4}{x} \\4 = 16x\\x = \frac{1}{4}

Thus the value of x when y = 16 is <u>1/4</u> or the <u>third choice</u>.

Hope that helps!

Answer:

x = 1/4

Step-by-step explanation:

To solve, we need to find the constant of proportionality (k) which is defined by the equation:

yx = k

(68)(1/17) = k\\k = 4

Therefore when y= 16,

16x = 4\\x= \frac{1}{4}

1) Definitions:

1.1) Inverse statement: negating the hypothesis and the conclusion of the original statement, i.e.:

conditional statement: p → q

inverse: ~p → ~q (the symbol ~ means the negation)

1.2) Converse statement: switching the hypothesis and the conclusion of the conditional statement, i.e.:

conditional statement: p → q

converse: q → p

2)  converse of the given statement

conditional: <span>If a line is vertical, then it has undefined slope.

converse: switch the hypothesis and the conclusion

if a line has undefined slope, then it is vertical <------- answer

Answer:

23.2

Step-by-step explanation:

15.7 - (-7.5) = 15.7 + 7.5 (because if there's 2 negative sign it makes the number positive)

Hunter-Best [27]

Answer: Area = 1500 feet^2

Step-by-step explanation:

Jim is enclosing a rectangular garden with 170 feet of fencing. This means the perimeter of the rectangular garden =170 feet

Let length = x

Let width = w

The length of the garden,x is 10 feet more than twice it's width, w. This means

x =10+2w---------1

Perimeter = 2x+2w =170---------2

Putting equation 1 in equation 2,

2(10+2w) +2w= 170

20 + 4w +2w = 170

6w = 170-20=150

w = 150/6

= 25feet

Put w=25 in equation 1

x =10 +2×25= 10+50=60 feet

Area = length × width = x×w

= 60×25=1500feet^2
