Mathematics

Answer:

n\geq -1

Step-by-step explanation:

19n+20\geq 1

(19n+20)+(-20)\geq 1+(-20)

19n\geq -19

\frac{19n}{19} \geq \frac{-19}{19}

n\geq -1

19n + 20 \geqslant 1

19n + 20 - 20 \geqslant 1 - 20

19n \geqslant  - 19

\frac{19n}{19} \geqslant  \frac{ - 19}{19}

n =  - 1

F(x)=3x-6 find f(4) I
Akimi4 [234]
To find f(4), you want to substitute x for 4 in the equation. It would look like:

f(4) = 3(4) - 6

Then, just do the math:

f(4) = 12 - 6
f(4) = 6

Hope this helps! :)

What is the value of f^-1(0)?<br><br><br><br> Please help! It’ll be greatly appreciated!
Leya [2.2K]

Answer:

f^{-1}(0)=6

Step-by-step explanation:

So, we have the graph y=f(x).

And we want to find:

f^{-1}(0)

Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:

f^{-1}(0)=y

This means that we have the point:

(0,y)

So, to find our solution, we will swap the x- and y-coordinates. This gives us:

(x,0)

So, simply need to find the x-coordinate such that y is 0.

From our graph, we can see the point (6,0). In other words:

f(6)=0

So:

f^{-1}(0)=6

And we're done!

HEEELLLPPP PLEEAAASEEE
Pavel [41]

Answer:

B.  y = 2.5

Step-by-step explanation:

Diane's average speed=  25/y  km/h.

Ed's speed= (25/y) - 6 km/h.

Ed walks 25-3 = 22 km.

Consider Ed's journey:

Speed = distance / time so:

(25/y) - 6  = 22 / (y + 3)    ( 3 hours longer = y + 3)

(25 /y - 6)(y + 3) = 22

25 + 75/y - 6y - 18 = 22

6y - 75/y = 25 - 18 - 22

6y - 75/y + 15 = 0

6y^2 + 15y - 75 = 0

2y^2 + 5y - 25 = 0

(2y - 5 )(y + 5) = 0

y = 2.5, -5.

y = 2.5   ( as it must be positive.
