The perimeter is 20 units
Step-by-step explanation:
The end-point of a side of square can be used to calculate length of a side. And the side will be used to calculate the perimeter.
Given
(3,-1) and (7,2)
Let
(3,-1) = (x1,y1)
(7,2) = (x2,y2)
We have to calculate the distance
The formula for distance is:
Let s be the side of a square
then,
The side of square is 5 units. Then,
The perimeter is 20 units

Answer:
(-♾, ♾)
Step-by-step explanation:
A quadratic can accept any real x value. So the domain is All Real Numbers. This in interval notation is
(-♾, ♾)
This is read as negative infinity to positive infinity
Answer:
x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52
subtract 3 from both sides
7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7
Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
To find out what's the weight missing we must subtract the expected weight from the actual weight.
The expected weight is 140kg, the actual weight is 132kg and 9 hectograms, remember that 1 hectogram 0.1kg, then 9 hectogram is 0.9. Then the actual weight is 132.9kg.
The weight of the missing equipment will be
The weight of the missing equipment is 7.1 kg
