Answer:
f⁻¹(x) = \frac{7x-3}{4}

Explanation:
To get the inverse of a function, we have to follow these steps:
1- replace f(x) with y
2- swap the x and y variables
3- solve for y
4- replace y with f⁻¹(x)

Applying this to the given as follows:
f(x) = \frac{4x-3}{7}

Step 1: replace f(x) with y:
y = \frac{4x-3}{7}

Step 2: swap the x and y variables:
x = \frac{4y-3}{7}

Step 3: solve for y:
7x = 4y - 3
4y = 7x - 3
y = \frac{7x-3}{4}

Step 4: replace y with f⁻¹(x):
f⁻¹(x) = \frac{7x-3}{4}

Hope this helps :)

Answer:

3. D) (-8, -17)

2. D) (-15, -16)

1. B) (3, -4)

Step-by-step explanation:

3.

{y = 3x + 7

{y = x - 9

x - 9 = 3x + 7

-3x - 3x

____________

−2x - 9 = 7

+ 9 + 9

__________

−2x = 16

____ __

−2 −2

-8 = x[Plug this back into both equations above to get the y-coordinate of −17]; -17 = y

__________________________________________________________

2.

{−4x + 3y = 12

{−2x + 3y = −18

−½[−4x + 3y = 12]

{2x - 1½y = −6 >> New Equation

{−2x + 3y = −18

_______________

1½y = −24

____ ____

1½ 1½

-16 = y[Plug this back into both equations above to get the x-coordinate of −15]; -15 = x

__________________________________________________________

1.

{−10x - 3y = −18

{−7x - 8y = 11

−⅜[−7x - 8y = 11]

{−10x - 3y = −18

{2⅝x + 3y = −4⅛ >> New Equation

_________________

−7⅜x = −22⅛

______ _____

−7⅜ −7⅜

3 = x[Plug this back into both equations above to get the y-coordinate of −4]; -4 = y

I am joyous to assist you anytime.

In a certain small town, 3 professional burglars are currently out of prison: Alex, Becky, and Carl. Alex has in the past commit
NeX [460]

Answer:

Answer explained below

Step-by-step explanation:

Alex has in the past committed 55% of the burglaries committed by the three, Becky 31%, and Carl the rest, hence

probability, P(Carl doing a burglary) = 1 - P(Alex or Becky doing a burglary)

= 1 - (0.55 + 0.31)

= 0.14

a) P(next burglary in town is the burglary of a residence) = P(Alex did a burglary of a residence) + P(Becky did a burglary of a residence) + P(Carl did a burglary of residence

= 0.55*1/3 + 0.31*0.5 + 0.14*1

= 0.4783

b)From  Bayes' Theorem: P(A | B) = P(A & B) / P(B)

Hence,

P(Becky | a resident reports a home burglary) = P(Becky did a burglary of a residence) / P(burglary of a residence)

= (0.31 * 0.5)/0.4783

= 0.3240
