Answer:

7

Step-by-step explanation:

By Basic proportionality theorem:

\frac{10}{8}  =  \frac{3x - 6}{12}  \\  \\  \frac{10 \times 12}{8}  = 3x - 6 \\  \\  \frac{120}{8}  = 3x - 6 \\  \\ 15 = 3x - 6 \\ 15 + 6 = 3x \\ 21 = 3x \\  \frac{21}{3}  = x \\ 7 = x \\  \\  \huge \red { \boxed{x = 7}}

Which set of parametric equations represents the following function? y=/x+3?
Darina [25.2K]
The given equation is:

y= \sqrt{x+3}

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

x=5t, y= \sqrt{5t+3}

From first equation, we can write t =x/5. Using this value in second equation, we get:

y= \sqrt{5( \frac{x}{5} )+3}  \\  \\ 
y= \sqrt{x+3}

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A

Suppose S is a recursively defined set, defined by - the number 1 is in S - if n is in S, then so is 3n + 2 - if n is in S, then
Tatiana [17]

Answer:

See answer below

Step-by-step explanation:

Using structural induction, we would have to prove that 1 and all the numbers derived from this fact, have the property.

That is to say, we would have to prove that

1, 3*1+2, 5*1-1 and 1+7 = {1, 4, 5, 8} have the property we want to prove S has.
