Answer:

Step-by-step explanation:

f(x) = 3x - 5

g(x) = - 2x + 7

<em>(a)</em>. <em>f(g(1)) = 10</em>

g(1) = - 2(1) + 7 = 5

f(5) = 3(5) - 5 = <em>10</em>

<em>(b).</em> <em>f(g( - 4)) = 40</em>

g( - 4) = - 2( - 4) + 7 = 15

f(15) = 3(15) - 5 = <em>40</em>

<em>(c).</em> <em>g(f( - 2)) = 29</em>

f( - 2) = 3( - 2) - 5 = - 11

g( - 11) = - 2( - 11 ) + 7 = <em>29</em>

<em>(d).</em> <em>g(f(3)) = - 1</em>

f(3) = 3(3) - 5 = 4

g(4) = - 2(4) + 7 = <em>- 1</em>

The sum of five consecutive positive integers is 2020. Find the largets of these numbers.
Alona [7]

Answer:

406

Step-by-step explanation:

let the 5 consecutive positive integers be

n , n + 1 , n + 2 , n + 3 , n + 4 , then

n + n + 1 + n + 2 + n + 3 + n + 4 = 2020

5n + 10 = 2020 ( subtract 10 from both sides )

5n = 2010 ( divide both sides by 5 )

n = 402

then

largest integer = n + 4 = 402 + 4 = 406

If m=(2x+1) and n=(6) and m+n=(9). Find x<br>​
gregori [183]

Answer:

\Large \boxed{x=1}

Step-by-step explanation:

Substitute m=(2x+1) and n=(6) in m+n=(9).

We are finding the value of the x variable.

2x+1+6=9

Add the numbers on the left side of the equation.

2x+7=9

Subtract 7 from both sides.

2x+7-7=9-7

2x=2

Divide both sides by 2.

\displaystyle \frac{2x}{2}=\frac{2}{2}

x=1

The value of the x variable is 1.

In this card game, a player is dealt 10 cards. A player wins $1,000,000 if he is dealt 8 hearts. Use combinatorics to set up you
denis23 [38]

Assume a standard deck of 52 cards with 4 suits of 13 cards each.

a. There are \dbinom{13}8\dbinom{39}2 ways of being dealt a hand consisting of 8 hearts and 2 non-hearts, so the probability of being dealt such a hand is

\dfrac{\dbinom{13}8\dbinom{39}2}{\dbinom{52}{10}}\approx0.0000602823

b. This time, the non-hearts specifically belong to the suit of diamonds, for which there are \dbinom{13}2 ways of getting drawn, so the probability is

\dfrac{\dbinom{13}8\dbinom{13}2}{\dbinom{52}{10}}\approx0.0000063455
