The table and the graph below each show a different relationship between the same two variables, x and y:

The value of y would be 20 times more valuable than 12 because the pattern for this table is y=20x. Let me know if I'm right :)

I need help with this question

Murrr4er [49]

The number of cows is given by

$14\cdot 2^{\frac{y}{5}}$

So, after $k$ years, the number of cows will be

$14\cdot 2^{\frac{y+k}{5}}$

We want this number to be twice as much as the original:

$14\cdot 2^{\frac{y+k}{5}} = 2(14\cdot 2^{\frac{y}{5}})$

First of all, we can cancel 14 from both sides:

$2^{\frac{y+k}{5}} = 2\cdot 2^{\frac{y}{5}}$

Finally, on the right hand side, we can use the exponent rule

$a^b\cdot a^c=a^{b+c}$

to get

$2^{\frac{y+k}{5}} = 2^{\frac{y}{5}+1}$

To solve this equation, we must impose that the two exponents are the same:

$\dfrac{y+k}{5} = \dfrac{y}{5}+1 \iff \dfrac{y+k}{5} = \dfrac{y+5}{5}$

And clearly this is true if and only if $k=5$ . So, it will take 5 years for the cow heard to double in number.

You can do the exact same steps to find the doubling time for the sheeps.

Which equation shows the relationship in the table below X 3, 5, 8, 11 Y 7 ,11, 17, 23 a y=2xb y=x+4 c y=2x+1 d y=2x+4

ANSWER

$c)\text{ }y=2x+1$

EXPLANATION

We want to find the equation for the relationship shown in the table.

The relationship shown in the table represents a linear relationship. The general form of a linear equation is:

$y=mx+b$

where m = slope

b = y-intercept

To find the slope of the equation, apply the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

where (x1, y1) and (x2, y2) are two sets of values from the table.

Let us take (3, 7) and (5, 11) as (x1, y1) and (x2, y2)

Hence, the slope of the equation is:

$\begin{gathered} m=\frac{11-7}{5-3}=\frac{4}{2} \\ m=2 \end{gathered}$

Now, to find the equation of the line, apply the point-slope method:

$y-y_1=m(x-x_1)$

Therefore, the equation that shows the relationship in the table is:

$\begin{gathered} y-7=2(x-3) \\ y-7=2x-6 \\ y=2x-6+7 \\ y=2x+1 \end{gathered}$

The correct option is option C.
