Help with my homework pls<br> Solve the compound inequality y + 7 ≥ –1 and y∕4 + 3 ≤ 5.

Marianna [84]

Answer:

-8 ≤ y ≤ 8

Step-by-step explanation:

Subtract 7 from the first one:

y ≥ -8

Subtract 3 from the second one, then multiply by 4.

y/4 ≤ 2

y ≤ 8

Now, you can write these as a compound inequality:

-8 ≤ y ≤ 8

_____

<em>Additional comment</em>

You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:

2 > 1

-2 < -1 . . . . . multiplied above by -1.

For which value of a does the following system of equations have no solution? -x+6y=7 , -5x+10ay=32

dlinn [17]

Remark

If the lines are parallel, there are no solutions to the system of equations. Start with the equation you know the most about.

x + 6y = 7 Subtract x from both sides

x - x + 6y = 7 - x Combine

6y = - x + 7 Switch and divide by 6

y = -x / 6 + 7/6

The general equation for a line is y = mx + b where m is the slope of the line.

m = - 1/6

================

Now look at the second equation

10ay - 5x = 32 Add 5x to both sides

10ay = 5x + 32 Divide by 10a

y = (5/10a)x + 32/(10a)

===============

Now you must make

5/10a = - 1/6 Cross Multiply

5* 6 = - 10a * 1

30 = - 10a Divide by - 10

a = 30 / - 10

a = - 3

So these two equations will have no solution when a = - 3

The Problem of the Points. Two players engage in a game. They are equally matched, and the chances of winning a point are the sa

Dominik [7]

Answer:

Player A receives $77.34375 of the sakes

Player B receives $22.65625 of the stakes

Step-by-step explanation:

Given that at the time the game was interrupted, we have;

The number of points player A has = 7 points

The number of points player B has = 5 points

The amount the first player to score 10 points wins = $100

The number of points remaining for player A to win the game = 3

The number of points remaining for player B to win the game = 5

Therefore, the number of trials remaining for a winner to emerge = 3 + 5 - 1 = 7 trials

We take the probability that Player A wins a point as success

We find the likelihood of Plater A winning by using binomial theory as follows;

$P(S) = \sum\limits_{j=3}^7 \dbinom{7}{3} \cdot \dfrac{1}{2^7} = \dfrac{35}{128} + \dfrac{35}{128} + \dfrac{21}{128} + \dfrac{7}{128} + \dfrac{1}{128} = \dfrac{99}{128}$

Therefore, given that the likelihood of Player A winning = 99/128

The stakes should be divided such that Player A gets 99/128 share of the stakes while Player B gets 1 - 99/128 = 29/128 share of the stakes

Therefore, Player A gets (99/128) × $100 = $77.34375

Player B gets (29/128) × $100 = $22.65625
