A deck of 14 cards numbered 1 through 14 is dealt to Ken and Gunther so that each gets 7 cards. Each player's score is the sum o

aliya0001 [1]

Answer:

The different winning scores possible are 25 (from 28 to 52).

Step-by-step explanation:

The minimum score obtained by a player will be 28.

since, we divide 1-7 numbered to one and 8-14 to the other player such that one receives the maximum and the other receives the minimum.

the least minimum possibility is :28 as one get the card as(1,2,3,4,5,6,7).

while the other player gets 77 sum and loses.

for increasing this score now we give the number 1,2,3,4,5,6,8 to one of the player so that they sum upto 29 and will get the minimum score and wins while the other player gets 76 sum with the help of numbers{9,10,11,12,13,14,7} and loses.

next possible minimum sum to win will be 30 by assigning 1,2,3,4,5,6,9 whereas the other gets the sum 75 and loses.

continuing in the same way we see that the minimum sum obtained to win will be 52( by assigning 2,3,6,7,9,12,13) while the other gets the sum 53 and loses.

Hence, there are total 25 winning scores possible. (from 28 to 52 i.e. 52-28=25).

The system of linear equations -2x+y=8 and -3x-y=7 is graphed below. What is the solution to the system of equations? (–3, 2) (–

Slav-nsk [51]

Answer:

x = -3 , y = 2

Step-by-step explanation:

Solve the following system:

{y - 2 x = 8 | (equation 1)

{-3 x - y = 7 | (equation 2)

Swap equation 1 with equation 2:

{-(3 x) - y = 7 | (equation 1)

{-(2 x) + y = 8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{-(3 x) - y = 7 | (equation 1)

{0 x+(5 y)/3 = 10/3 | (equation 2)

Multiply equation 2 by 3/5:

{-(3 x) - y = 7 | (equation 1)

{0 x+y = 2 | (equation 2)

Add equation 2 to equation 1:

{-(3 x)+0 y = 9 | (equation 1)

{0 x+y = 2 | (equation 2)

Divide equation 1 by -3:

{x+0 y = -3 | (equation 1)

{0 x+y = 2 | (equation 2)

Collect results:

Answer: {x = -3 , y = 2

What is the step by step process of this problem? 6+2[-8-3(2x+4)]+10x

Romashka [77]

<u>So with more than one pair of parentheses, you must start from the inside and make your way outside.</u>

So firstly, distribute -3 to (2x + 4):

$6+2[-8-6x-12]+10x$

Next, combine like terms:

$6+2[-6x-20]+10x$

Next, distribute 2 to [-6x - 20]:

$6-12x-40+10x$

Lastly, combine like terms and <u>your final answer will be $-2x-34$ </u>

What is the equation of the line that is perpendicular to the

soldi70 [24.7K]

Answer:

Option (4). y = 3x - 5

Step-by-step explanation:

Given question is incomplete; here is the complete question.

What is the equation of the line that is perpendicular to the given line and passes through the point (3, 4)?

y = –1/3x + 5

y = –1/3x + 3

y = 3x + 2

y = 3x − 5

Line given in the graph passes through the points (-3, 2) and (0, 1).

Slope of the given line = $\frac{y_{2}-y_1}{x_2-x_1}$

m = $\frac{2-1}{-3-0}$

m = $-\frac{1}{3}$

Let the equation of a line perpendicular to this line is,

y - y' = m'(x - x') [Given line passes through (x', y')]

By the property of perpendicular lines,

m × m' = -1

( $-\frac{1}{3}$ ) × m' = -1

m' = 3

Equation of the perpendicular line will be,

y - 4 = 3(x - 3)

y - 4 = 3x - 9

y = 3x - 5

Option (4) will be the answer.
