Given the function f(x) = 0.5(3)x, what is the value of f−1(7)?

I'm assuming you need the product of the inverse equation f with x=7

First we find the inverse of f(x)
f(x)=y=0.5(3)x
---------> x= 0.5(3)y
---------> y= x/.5(3)

The inverse is
f-1(x)= x/.5(3)

With x=7
f-1(x)=x/.5(3)
f-1(7)=7/.5(3)
=14/3
= 4.6

Answer:

Perimeter is 17.07

Step-by-step explanation:

We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.

We need to use the Pythagorean theorem to get the length of DE.

$DE = \sqrt{5^{2} +5^{2}}=\sqrt{50} = 7.07\\$

So the perimeter of DEF is 5 + 5 + 7.07 = 17.07

Part a : solve - vp + 40 < 65 for v .

miskamm [114]

Answer:

$\large \text{Part a:}\\\\for\ d-\dfrac{25}{d}}$

$\large\text{Part b:}\\\\\boxed{r=\dfrac{7}{3}w-5}$

Step-by-step explanation:

$\text{Part a}\\\\-vp+400,\ \text{then}\ \boxed{v>-\dfrac{25}{d}}\\\\\text{if}\ d$

$\text{Part b}\\\\7w-3r=15\qquad\text{subtract 7w from both sides}\\\\-3r=-7w+15\qquad\text{divide both sides by (-3)}\\\\\boxed{r=\dfrac{7}{3}w-5}$

How many solutions does the following equation have? 10x-1=10x+4

zimovet [89]

Your answer is no solution.
Because if we transpose 10x to the left hand side with a change in the symbol, then it will become 0.
10x - 1 = 10x +4
or, 10x - 10x = 4 + 5
or, 0 = 9
Hence, the equation has <em><u>no solution</u></em>.

Hope you could get an idea from here.
