Select the equations corresponding to d, the distance between points (2, -6) and (2, 5).

a) d = |-6| – |5|
b) d = |2| – |2|
c) d = |5| – |-6|
d) d = |5| + |-6|
e) d = |2| + |2|
f) d = |-6| + |5|

Answers

The distance between points  (2, -6) and (2, 5) is d = |-6| + |5|.

In the first step, we plot the two points. Then, connect the two points. Count the distance between Quadrant I and Quadrant IV.

Quadrant I contains 5 units and quadrant IV contains 6 units. We know that the vertical line denotes the y-value. Therefore, we take the Quadrant IV value as -6.

Since, we use the determinant sign the result will be d = |-6| + |5|.

To find the distance between two points:

Answer:

C.)

Step-by-step explanation:

The graph is positive this time, so right away you can eliminate A and B.

If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.

Answer: C: 1/2

Step-by-step explanation:

Rise over run tells us that this graph is going up 1 and right 2. Since it’s going up and right it’s going to be positive and since we do rise over run on our slope fraction, that leaves us with C, 1/2.

Solving Quadratic Equations-factoring
How do find what b could be? My book says to factor completely.
3b²+15b+12=0

Answers

Answer:

b  =  −1

b  =  −4

Step-by-step explanation:

Common Factor

Divide both sides of the equation by the same term

Use the quadratic formula

Answer:

-1 or -4

Step-by-step explanation:

first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b

doing this, we would have our two numbers to be

12b and 3b

replace these two numbers with 15b in the equation

3b² + 12b + 3b + 12=0

(3b²+12b) + (3b+12)=0

3b(b+4)+3(b+4)=0

note: the numbers in the brackets must be the same

(3b+3)(b+4)=0

therefore, 3b + 3= 0 or b + 4= 0

3b+3= 0

3b=-3

b=-3/3

b=-1

or

b+4=0

b=-4

Lauren opened a lemonade stand on her street. It costs her $8.00 to buy the supplies each day, and she sells lemonade for $2.50 a cup.

Answers

Answer:

180.5 cups

Step-by-step explanation:

profit is 175, she spends $8 on supplies each day. 8+175= 183. 183 is what she initially made each day. 183 divided by 2.5= 180.5

A construction company needs to remove 2 1/6 tons of dirt from a construction site. they can remove 7/8 of dirt each hour. what is the total number of hours it will take to remove the dirt each hour? write your answer as a mixed number and simplest form.

Answers

Answer: 2.357hrs

Step-by-step explanation:

Rate of dirt removal (rate) = 7/8 tons/hr

Total dirt removed (dirt) = 2 1/16 tons

Each hour, 7/8 tons of dirt will be removed, so if you work for h hours, you will have removed 7/8 * x tons of dirt. You can set up an equation as follows:

7/8 tons/hr * h hr = 2 1/16 tons (see how the units work out to give you tons)

Rearrange and solve for h:

h = (2 1/16) / (7/8) = 33/14 hrs = 2.357hrs

Answer above is correct :)) hope this helps!

Select the statement that describes the expression 6 x one third x (12 − 3).

A 6 times one third the quotient of 12 and 3
B 6 times one third the sum of 12 and 3
C 6 times one third the product of 12 and 3
D 6 times one third of the difference of 12 and 3

Answers

Answer:

D

Step-by-step explanation:

6 x 1/3 = 2

1/3 x (12-3) = 2 x 9

2 x 9 = 18

A = 2 (12/3) = 2 x 4 =  8

B = 2 x 15 = 30

C = 2 x 36 = 72

D = 2 x 9 = 18

the answer would be D.

Round to the nearest whole feet.

Answers

Answer:

2544 ft

Step-by-step explanation:

First, find the area of the pool.

A= πr²

if we fill in the radius, use 3.14 for pi, and solve for A, that's

A=(3.14)(20.5)²≈1319.585

The area of the pool is roughly 1319.585 ft

Now, we find the area of the triangle

A=(ab)÷2

put in 'a' and 'b' (the triangle legs) and solve

A=(84×92)÷2=3864

Finally, subtract the area of the pool from that of the triangle

3864-1319.585=2544.415 which rounds to 2544 ft

hopefully that helps and you might want to double check but that's what I got :)

What is the cost of one sandwich?


What is the cost of 1 sandwich 1 salad and 1 juice?

Answers

Answer:

Below in bold.

Step-by-step explanation:

Let cost of sandwich = s,  juice = j and salad = d.

2s + j = 500     (A)

s + d = 510       (B)

d + j =  530      (C)

Equation  (C) - (B)   ( to eliminate d):

j - s = 20          (D)

(A)  - (D) =   (to eliminate j):

2s - (-s) = 480

3s = 480

s = 160

A sandwich costs E 1.60.
