Question says to find the correct function from the given choices for given graph. By looking at the graph we find that there are steps so it is clear that it is graph of floor function which is usually written as y=[x]

Graph of y=[x] pass throuh origin but given graph is above the origin so that means there must be some vertical shift.

Since given graph is above origin about 7 units so that indicates, there is 7 unit upward shift in the parent function y=[x]

Hence required function can be found by adding 7 to y=[x]

Hence final answer is y=[x]+7.

Please help meeee!!!!!!!!

ivanzaharov [21]

Answer:

$840$

Step-by-step explanation:

This is a good example of permutations. For the first slot on his shelf, Dylan has 7 trophies to choose from. Then 6, 5, and so on. Since he is only fitting 4 trophies on his shelf, we only continue until we have the slots filled. Thus, we have $7\cdot 6 \cdot 5\cdot 4=\boxed{840\:\text{ways}}$ to do so.

*Note: We do not divide by $4!$ because in this case, order matters. A different order of the same four books still produces different arrangements, so the order matters.

The function f(x)=2/3x-4 was replaced with f(x+k)=2/3x-6 what is the value of k

HACTEHA [7]

Answer:

The given function $f(x)=\frac{2x}{3}-4$ was replaced with $f(x+k)=\frac{2x}{3}-6$ then the value of k is -3

that is k=-3.

Step-by-step explanation:

The given function is $f(x)=\frac{2x}{3}-4\hfill (1)$

and when x=x+k then $f(x+k)=\frac{2x}{3}-6\hfill (2)$

Now to find the value of k:

Put x=x+k in the function f(x)

$f(x)=\frac{2x}{3}-4$

$f(x+k)=\frac{2(x+k)}{3}-4$

$f(x+k)=\frac{2x+2k}{3}-4\hfill (3)$

Now comparing equations (2) and (3) we get

$f(x+k)=\frac{2x+2k}{3}-4=\frac{2x}{3}-6$

$\frac{2x+2k}{3}-4=\frac{2x}{3}-6$

$\frac{2x+2k}{3}-4-\frac{2x}{3}+6=0$

$\frac{2x}{3}+\frac{2k}{3}-4-\frac{2x}{3}+6=0$

$\frac{2k}{3}+2=0$

$\frac{2k}{3}=-2$

$k=\frac{-2\times 3}{2}$

$k=-3$

Therefore k=-3

Therefore the given function $f(x)=\frac{2x}{3}-4$ was replaced with $f(x+k)=\frac{2x}{3}-6$ then the value of k is -3

that is k=-3.

Which pair of inequalities is shown in the graph?

nikitadnepr [17]

Answer:

y > x - 5

and

y > -x + 1

Step-by-step explanation:

Since the solution goes above both the lines, we know that the inequalities must have a y > aspect. To get the next portion, simply find the equation of the lines. This would get you y > x - 5 and y > -x + 1.
