Answer:

f^{-1}(x)=\dfrac{x+3}{4}

Step-by-step explanation:

Given: f(x)=4x-3

We need to find the inverse.

Step 1: Set f(x)=y

y=4x-3

Step 2: Switch x and y

x=4y-3

Step 3: Solve for y

x+3=4y

y=\dfrac{x+3}{4}

Hence, The inverse of given function is y=\dfrac{x+3}{4}

<span>f(x) = 4x - 3
.
The problem asks you to find f(-1).
.
All that this is telling you to do is to evaluate f(x) when x equals -1. So, just go to the
given f(x) and substitute -1 for every x. 
.
Starting with:
.
f(x) = 4x - 3</span>

The answer is:  "p = 2" .
______________________________________________________
Explanation:
______________________________________________________
Given:
______________________________________________________
  " 8p + 8 = 10 + 7p " ;   Solve for "p" ; 

Subtract "7p" from each side of the equation; & subtract "8" from each side of the equation; as follows:

8p + 8 − 7p − 8 = 10 + 7p − 7p <span>− 8 ;

The points plotted below satisfy a polynomial equation. What type of extreme value does the graph have in the part that is visib
bezimeni [28]
Hi!

The graph shows an A) Maximum

A Maximum value appears in a graph when all other values of the polynomial are smaller in value i.e. are under it in an X-Y plot. This is expressed mathematically as:

There is a maximum if for a given x*: f(x*) ≥ f(x) for all x. 

In the graph, you can clearly see that there is a value that is higher than all the others, so this value is a Maximum.

HELP ME FIND THE ANGLE<br><br><br><br><br> HELP ME FIND ANGLE A
romanna [79]

Answer:

32 degrees

Step-by-step explanation: So they tell you BE is congruent to BC so triangle BCE is isosceles. We know that angle C is 35 degrees and the triangle is isosceles so angle E is 35 degrees too. Now we do 180-(35+35) and that equals 110 so angle B is 110. And we know that angle EBC and FBA are supplementary angles so 180-110 is 70 degrees so angle FBA is 70 degrees and you can do the same thing with angle DFB and AFB so 180-102 degrees is 78 degrees and to find angle a you just do 180-(70+78) and that equals 32 degrees so angle A is 32 degrees. :)
