Answer:

c = 9b/c

Step-by-step explanation:

If c varies directly with b and inversely with a, then this may be written mathematically as;

c = kb/a

Therefore;

k = ac/b

Hence in this case;

k = (6 × 33)/22

   = k

Therefore; the equation connecting the variables is;

c = 9b/a

Answer:

c= 9b/a

Step-by-step explanation:

The statement "y varies directly as x," means that when x increases, y increases by the same factor. The statement "y varies inversely as x means that when x increases, ydecreases by the same factor.

Then, we can say that:

c ∝ b, thus c= kb and c = k/a.

Using both equations we have that:

c= kb/a

Given that a=6, b=22 and c=33 we have that:

33 = 22k/6

Solving for k:

k=9.

Then the equation that models the situation is:

c= 9b/a

agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

<u>Solution 1</u>

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

<u>Solution 2</u> (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

Please correct me if I'm wrong.

Answer:

The answer is (x,y)=(-10,-7)

Step-by-step explanation:

  • The solution comes from replace x= -10 into the equation of y=2/5 x -3.
  • Replacement of x= -10 into y = 2/5 x -3 results: y=\frac{2}{5}\times{(-10)}-3=2\times{(-2)} -3=-4-3=-7.
