A line passes through (1, 8) and is perpendicular to the graph of y = 2x+1. What equation
represents the line in slope-intercept form?

Answers

Answer:

y = -1/2x + 17/2

Explanation:

y = 2x + 1 is in slope intercept form

in the equation y = mx+b, m is the slope, and in the equation m =2

the slope of a perpendicular line is the negative reciprocal of the other slope.

slope of perpendicular= -1/m = -1/2

y = -1/2x + b

now find b by substituting in (1,8) into the partial equation

8 = -1/2 + b

b = 8+ 1/2

b = 17/2

Answers

Answer:

Decimal = 0.6

Percentage = 60%

Step-by-step explanation:

Let's simplify the fraction.

[tex] \frac{120}{200} = \frac{60}{100} = 0.6[/tex]

Hence the Decimal is 0.6

To express 120/200 in percentage , we have to multiply the fraction with 100.

[tex] \frac{120}{200} \times 100 = \frac{120}{2} = 60\%[/tex]

Hence the percentage value is 60%

Pleasee help(GIVING BRAINILEST) Tyra's family is spending the afternoon in Millersville. They plan to see a movie and then explore the town. The movie will cost the family $36, and parking costs $4 per hour.
How long will the family be able to spend in Millersville if they want to spend less than $60 and they don’t have any other expenses?

Follow the steps to answer this question.

1. Write an inequality that shows that Tyra's family spends less than their limit. Explain how you wrote the inequality, and define any variables used. (2 pts)

Write your answer in the space below.










2. Solve your inequality. Show your work. What does your solution mean? (3 pts)

Write your answer in the space below.

Answers

Answer:

1.) 4x + 36 < 60

2.) The family must spend less than 6 hours in Millersville watching the movie.

Step-by-step explanation:

1.) In order to write an inequality to represent the situation, we need to consider all variables. The main resultant / dependent variable is the money spent. The independent variable is the time.

Let x = time  and y = money spent.

y = mx + b

Since the entrance fee for the movie is $36, we know that the b = 36. Since the rate of change is $4, you know that m = 4. Lastly, since the maximum amount of money the family has is $60, y = 60.

60 = 4x + 36

Finally, since the money spent must always be LESS THAN 60, 4x + 36 < 60

2.) Soling the Inequality:

Firstly, isolate the 4x by subtracting 36 from both sides.

4x + 36 -36 < 60 - 36

4x < 24

Next, divide both side by 4 in order to isolate x. Since 4 is positive, DO NOT flip the less than

4x/4 < 24/4

x < 6

Since x represents the time, time < 6 hours, meaning that the family must spend less than 6 hours in Millersville watching the movie.

Answer:

1. 60>4x+36

2.6>x

Step-by-step explanation:

60 is the total amount of money the family has to spend, they want to spend less than that so...

60 is greater than what they will spend (60>)

the (x) is the amount of hours the family will spend at the city. parking cost 4 so that means 4 dollars per hour.

the 36 is what they have to initially spend to watch the movie

if you subtract both sides of the (>) by 36 you get

24>4x

then you divide both sides by 4 to get the (x) by itself, which gets you

6>x

meaning that the amount of hours the family will spend at the city will have to be 5 hours

correct me if I'm wrong but i believe that this is the correct answer... i double checked

Answer:

A. y=2/3x-6

B. y=-3/2x+13

Step-by-step explanation:

If the line is parallel, then they have the same slope.

-2=2/3(6)+b

-2=4+b

-6=b

y=2/3x-6

If the line is perpendicular, then the slopes are opposite reciprocals.

1=-3/2(8)-b

1=-12=b

13=b

y=-3/2x+13

Step-by-step explanation:

A)

Paralle mean the same slope so 2/3 is the slope

Y+2=2/3(x-6)

Y+2=2/3x-4

Y=2/3x-6

B)

Perpendicular means that we flip the slope and change sign if it +or - so the slope will be -3/2

Y-1=-3/2(x-8)

Y-1=-3/2x+12

Y=-3/2x+13

Shauna is making accessories for the soccer team she uses 513.48 inches of fabric on headbands for 40 player and 4 coaches she uses 372.40 inches of fabric on wristbands for just the players how much fabric was used on a headband and wristband for each player?

Answers

Answer:

For each player:

Headbands = 11.67 inches of fabric

Wristbands = 9.31 inches of fabric

Step-by-step explanation:

Shauna is making accessories for the soccer team

For Headbands

She uses 513.48 inches of fabric on headbands for 40 player and 4 coaches

The total number of persons = 40 players + 4 coaches

= 44 persons

Hence:

44 persons = 513.48 inches

1 person = x

Cross Multiply

44x = 513.48 inches × 1

x = 513.48 inches/44

x = 11.67 inches per person

For Wristbands

She uses 372.40 inches of fabric on wristbands for just the players how much fabric was used on a headband and wristband for each player?

Number of players = 40

Hence

40 players = 372.40 inches

1 players = x inches

Cross Multiply

40x = 372.40 inches

x = 372.40 inches/40

x = 9.31 inches

Hence, 9.31 inches per player.

Therefore

For each player:

Headbands = 11.67 inches of fabric

Wristbands = 9.31 inches of fabric

Answers

The probability will be "0.578".

Given values,

p = 25%

or,

          = 0.25

q = 1-p

           = 1-0.25

           = 0.75

To find the probability that it takes Jeremiah fever than 4 attempts is given by,

→ [tex]P(M<4) = P(1-P)^{M-1}[/tex]

M = 1, 2, 3

→                  [tex]= P[(1-P)^{1-1}+(1-P)^{2-1}+(1-P)^{3-1}][/tex]

→                  [tex]= P[1+(1-P)+(1-P)^2][/tex]

→                  [tex]= 0.25[1+0.75+0.75^2][/tex]

→                  [tex]= 0.25\times 2.3125[/tex]

→                  [tex]= 0.578125[/tex]

Answers

Answer:

l = 7 m

w = 6 m

Step-by-step explanation:

l = 2w - 5

p = 2xl + 2xw

p = 2 x (l + w)

26 = 2 x (2w - 5 + w)

26 : 2 = 3w - 5

13 = 3w - 5

13 + 5 = 3w

3w = 18

w = 18 : 3 = 6 m

l = 2w - 5 = 2 x 6 - 5 = 12 - 5 = 7

so the dimention of rectangle is 7 m in length and 6 m in width
