Answer:

No solutions.

Step-by-step explanation:

If you normalize the second one by dividing by 2, you get:

y = 5/2x+4.

Now you see that both have the same slope (5/2). They are parallel lines that never intersect.

What is the inverse of the function f(x)=1/9x+2

Anna35 [415]

Answer:

$f^{-1}(x)=9x-18$

Step-by-step explanation:

we have

$f(x)=\frac{1}{9}x+2$

Let

$y=f(x)$

$y=\frac{1}{9}x+2$

Exchange variables x for y and y for x

$x=\frac{1}{9}y+2$

Isolate the variable y

$x-2=\frac{1}{9}y$

$y=9(x-2)$

$y=9x-18$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=9x-18$ -------> inverse function

I will give brainiest to whoever answers correctly !!

NemiM [27]

Step-by-step explanation:

A) In order to calculate the interest , we can use the following formula :

$P=P_{0}.(1+i)^{t}$

Where P is the interest , P0 is the initial value, i is the interest and t is the time.

So , using P0 =600,i= 0.0005768 and t=27 ,we have :

$P=600.(1+0.0005768)^{27} \\P=600.(1.01569)\\P=609.41$

Calculating only the interest, we have :

$I=609.41-600\\I=9.41\\$

So the interest is $9.41.

B) He paid the final value calculated above, that is , $609.41.

Fill in the blank #19

scoundrel [369]

Answer:

Step-by-step explanation:

2y + 1 + x + ? = 2y + 1 + 4x

Subtract 2y from each side

2y -2y+ 1 + x + ? = 2y-2y + 1 + 4x

1 + x + ? = 1 + 4x

Subtract 1 from each side

1 -1+ x + ? = 1 -1+ 4x

x + ? = 4x

Subtract x from each side

x-x+? = 4x-x

? = 3x

Which of the following is Not a true statement about absolute value? A. Absolute value is always positive B.The absolute value i

Svet_ta [14]

B is not true.

The absolutely value of zero is just zero. A and C are both saying the same thing really, just worded differently.

You left out an option D, but regardless B is untrue.
