What is the slope of (-3, -2) and (-1, -5) ??
Answers
Answer:
-3/2 or -1 1/2
Step-by-step explanation:
The slope, plugging into the equation (y_2-y_1)/(x_2-x_1) would be -5 + 2 / -1 + 3, or -3/2, which can also be - 1 1/2
Answer:
-3/2
Step-by-step explanation:
slope ('m') formula: (difference of the y-values) ÷ (difference of the x-values)
m = -2-(-5) ÷ -3-(-1)
m = 3 ÷ -2
slope = -3/2

Step-by-step explanation:
The angle opposite the shortest side is the smallest
The angle opposite the longest side is the largest
Shortest side is AC with ∠ B opposite , thus smallest
Longest side is AB with ∠ C opposite, thus largest
Then order of angles from least to greatest is
∠ B , ∠ A , ∠ C

please explain to me how to solve for x and y
Answers
Answer:
(x, y) = (6, 2)
Step-by-step explanation:
You solve for x and y by writing equations that reflect the relation applicable to the given geometry.
The diagonals of a parallelogram bisect each other. That means the halves of each diagonal are equal.
2x -4 = 4y . . . . . . down diagonal
x +4 = 7y -4 . . . . . up diagonal
__
We can subtract the first equation from 2 times the second equation to eliminate the x-variable.
2(x +4) -(2x -4) = 2(7y -4) -(4y)
2x +8 -2x +4 = 14y -8 -4y . . . . . . eliminate parentheses
12 = 10y -8 . . . . . . . . . . . . . . . . . collect terms
20 = 10y . . . . . . . . . . . . . . . . . . add 8
2 = y . . . . . . . . . . . . . . . . . . . . divide by 10
Substituting into the second equation gives ...
x +4 = 7(2) -4
x = 6 . . . . . . . . . . . . subtract 4
The values of x and y are (x, y) = (6, 2).

The distance between two cities is 180 km. The distance was
covered by a car at a rate of 50 km/h, by a bus at 45 km/h, by a
truck at 40 km/h, and a by a bicycle at 25 km/h. What is the constant of
variation?
Answers
Answer:
Step-by-step explanation:
he distance between two cities is 180 km.
Speed = distance/time
v = s/t from this we can calculate for time
Time = distance /speed
This distance was covered by a car at a rate of 50 km/h
Time taken by the car to cover this distance of 180km
= 180/50 = 3.6 hours
This distance was covered by a bus at 45 km/h
Time taken by the bus to cover this distance of 180km
= 180/45 = 4 hours
This distance was covered by a truck at 40 km/h
Time taken by the truck to cover this distance of 180km
= 180/40 = 4.5 hours
This distance was covered by a bicycle at 25 km/h
Time taken by the truck to cover this distance of 180km
= 180/25 = 7.2 hours
Therefore:
speed and time are directly proportional.
Speed, s is inversely proportional to time, t
xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation
Introducing constant of variation, k
s = k/t
When s = 25, t = 7.2
25 = k/7.2
k = 7.2× 25 = 180
So
s = 180/k

(3, $2560) & (4, $512)

Part B: Write an equation that can be used to find the value of the piano, v, after t years
Answers
Answer:
Part A would be: 3, $2560 & 4, 2048 I am pretty sure
Step-by-step explanation:
20% of 3,200 = 640
3,200-640= 2,560
then
20% of 2,560 = 512
2,560-512 = 2,048
hope this helps! :)
Part A: The first answer is correct, or (3, $2560) & (4, $2048)
Part B: V = 5,000(0.8)^t
5000 is the original price, 0.8 shows the value going down 20%, and t shows how many years.

On Thursday, a local hamburger shop sold a combined total of 444 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Thursday?
Answers
Answer:
They sold 111 Hamburgers
Step-by-step explanation:
Turn this into an equation: first, take the amount of hamburgers and call it 3x due to it being 3 times more than the amount of cheeseburgers, which we will can call x.
So, X+3X=444 is what you need to solve this. This is the same as 4x=444
So, x=111
Now, Input 111 for the final answer; 333 cheeseburgers and 111 hamburgers

when amy us doing he homework, she writes the divisor 76 as 67 by accident, and the result is a quotient of 15 and a reminder of 5. what is the correct quotient?
Answers
Answer:
13 r 22
Step-by-step explanation:
The dividend of Amy's division problem is d such that ...
d/67 = 15 +5/67
Multiplying by 67, we get ...
d = 15(67) +5 = 1010
When this is divided by 76, the result is ...
1010/76 = 13 22/76
The correct quotient is 13 remainder 22.
Which is greater 25% of 16 or 20% of 25
Answers
Answer:
20% of 25 is greater
Step-by-step explanation:
25% of 16 = 4
20% of 25 = 5
Answer:
20% of 25
Step-by-step explanation:
To find 25% of 16, we have to consider how much 25% is out of 100%
25/100 can be simplified to 1/4
So 1/4 of 16 (or 16/4) = 4
To find 20% of 25, we have to consider how much 20% is out of 100%
20/100 can be simplified to 1/5
So 1/5 of 25 (or 25/5) = 5
4 < 5
Therefore, 20% of 25 is greater than 25% of 16
