(8, 2); y = -2x + 4

A. y = 1/2x -2
B. y = -2x + 18
C. y = 1/2x - 6
D. y -2 = 1/2(x - 8)

Answers

Answer:

A is your answer.

Step-by-step explanation:

Perpendicular is opposite and reciprocol of the slope. Your slope is -2 so the opposite of that is positive 2, and the reciprocol is 1/2. When you graph that you should have a point at (8,2). y=1/2x -2

Answers

Answer:

Step-by-step explanation:

6 pizzas = 39 cups of flour

1 pizza = 39/6 cups of flour

4 pizzas = 39*4/6 cups of flour = 39*2/3 = 26 cups of flour

26 cups of flour = 4 pizzas

The cost of a car rental is ​$30 per day plus 20 cents per mile. You are on a daily budget of ​$94. Write and solve an inequality to find the greatest distance you can drive each day while staying within your budget. Find 2 other​ two-step inequalities with the same solutions.

Answers

STEP 1

determine inequality

Car rental= $30 per day

Mileage= $0.20 per mile

m= number miles driven

Add daily rental charge to the quantity of (number of miles driven multiplied by the per mile charge). This has to be less than or equal to the budget of $94 a day.

$30+ ($0.20 * m) ≤ $94

$30 + $0.20m ≤ $94

STEP 2

solve

$30 + $0.20m ≤ $94

subtract 30 from both sides

0.20m ≤ 64

divide both sides by 0.20

m ≤ 320 mile limit

ANSWER:

Inequality: $30 + $0.20m ≤ $94

320 miles is the daily mileage limit and can be driven daily to stay under (or equal to) the $94 daily budget.

Hope this helps! :)

How many solutions does this equation have? 18z + 7 = –20 + 18z + 15

Answers

Answer:

This equation has no solution.

Step-by-step explanation:

When you are in the process of solving this, you combine like terms and end up with 18z + 7 = 18z -5. When there is a common term on both sides, you cancel it. So in this case you would cancel the 18z on both sides. Then you would be left with 7 = -5, which is a false statement. 7 is not the same as -5. Therefore this equation does not have any solutions.

Sean got 4 over 5 pound of honey from a hive. He calculated the quotient of 4 over 5 ÷ 3 over 8 . Which statement shows the quotient and gives the most likely explanation of what Sean was trying to determine? (5 points)

He can make 2 2/15 bottles of honey with 3/8 pound of honey in each bottle.
He can make 12/40 of a bottle of honey with 3/8 pound of honey in each bottle.
He can get 2 2/15 pounds of honey if he divides the honey into 3/8 -pound portions.
He can get 12/40 pound of honey if he divides the honey into 3/8 -pound portions.

Answers

Answer:

The answer is A

Step-by-step explanation:

Writing the equation, it would look like (4/5) divided by (3/8) which gives you the answer 2 2/15 which is a mixed number btw. Only two of the answers uses this number, either A or C. C doesn't make any sense because the question already states that Sean has 4/5 pounds of honey. A makes sense because technically what you are doing is dividing the amount of honey Sean got into groups each holding 3/8 pounds.

For the data set 16, 17, 18, 19, 30, the mean is 20. What is the mean absolute deviation?

a. the mean absolute deviation is 20

b. the mean absolute deviation is 4

c. the mean absolute deviation is 16

d. the mean absolute deviation is 5​

Answers

Answer:

The mean absolute deviation is 4.

Step-by-step explanation:

Test appoved

For the data set 16, 17, 18, 19, 30, the mean is 20,  the mean absolute deviation is 4. Option B is the answer.

The mean absolute deviation

Calculate the mean:

(16 + 17 + 18 + 19 + 30) / 5

= 100 / 5

= 20

Find the absolute difference for each data point by subtracting the mean from each data point and taking the absolute value:

|16 - 20| = 4

|17 - 20| = 3

|18 - 20| = 2

|19 - 20| = 1

|30 - 20| = 10

Calculate the average of these absolute differences:

(4 + 3 + 2 + 1 + 10) / 5 = 20 / 5 = 4

Therefore, the mean absolute deviation (MAD) is 4.

The answer for number one is 36 square units because the rectangular area is 24 sq un and the triangular area is 12 sq un so I added them to get 36 sq un. The second answer is 40 sq un because if you cut the shape into 2 shapes you get 2 equal trapezoids. Each trapezoid is 20 sq un so I multiplied it by two to get 40 sq un. The third answer is 20 because the side triangles are 2 sq un each and the square on the bottom is 16 sq un. By the way, sq un means square units lol.
