Answer:

1,280

Step-by-step explanation:

prob(spots) = 12/180 = 1/15

so of the 1200 frogs, (1/15)(1200) should have spots, so ..

how many should not have frogs ?

Given that -6,-6 is on the graph of f x find the corresponding point for the function f(3/4x)
Liono4ka [1.6K]

Answer:

The corresponding point is <em>(-8, -6).</em>

Step-by-step explanation:

Given that

(-6,-6) lies on the graph of f(x)

A function is represented in the form:

y = f(x)

i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.

f(-6) = -6

Now, we have to find the corresponding point on f(\frac{3}{4}x).

We know the value of f(-6)

Let us find the value of x where \frac{3}{4}x becomes equal to -6

\dfrac{3}{4}x=-6\\\Rightarrow 3x=-24\\ \Rightarrow x =-8

So, let us put value of x = -8 in f(\frac{3}{4}x):

f(\frac{3}{4}\times (-8))\\\Rightarrow f(3\times (-2))\\\Rightarrow  f(-6) = -6(as per given statement)

So, the corresponding point is <em>(-8, -6).</em>
