(m) You said -1 - 3 = -2, but it's -4. That would make m = 2.
(b)That would make the equation: y = 2x + b, and when you plug in (3,3), you get 3 = 3(2) + b --> 3 = 6 + b --> -3 = b
(equation) That makes the equation y = 2x - 3
Every 30 minutes he earns 7 dollars... so 1 hour is 14 dollars (cheap money)
The answer is B :)
Answer:
Step-by-step explanation:
(a) A square has all the 4 sides being equal while a rectangle has four sides, with the opposite sides being parallel and the same length.
(b) The diagonals bisect the angles , the diagonals are perpendicular bisectors of each other
(c) A square has two pairs of parallel sides, four right angles, and all four sides are equal while the angles of a parallelogram are not right angles
(d) a rhombus can be a rectangle (if the angles of the rhombus are all 90 degrees), and a rectangle can be a rhombus (if the sides of the rectangle are all equal length). Opposite sides are parallel.
(e) a rhombus has two opposite internal angles of equal measure, a square has four right angles with equal measure

Answer: (b)
Step-by-step explanation:
Given
R is inversely proportional to A i.e
![R\propto \dfrac{1}{A}\\\\R=\dfrac{C}{A}\quad [\text{C=Constant}]](https://tex.z-dn.net/?f=R%5Cpropto%20%5Cdfrac%7B1%7D%7BA%7D%5C%5C%5C%5CR%3D%5Cdfrac%7BC%7D%7BA%7D%5Cquad%20%5B%5Ctext%7BC%3DConstant%7D%5D)
when ![R=4,\ A=100](https://tex.z-dn.net/?f=R%3D4%2C%5C%20A%3D100)
Insert the values to get C
![\Rightarrow 4=\dfrac{C}{100}\\\\\Rightarrow C=400](https://tex.z-dn.net/?f=%5CRightarrow%204%3D%5Cdfrac%7BC%7D%7B100%7D%5C%5C%5C%5C%5CRightarrow%20C%3D400)
When A=250
![\Rightarrow R=\dfrac{400}{250}\\\\\Rightarrow R=1.6](https://tex.z-dn.net/?f=%5CRightarrow%20R%3D%5Cdfrac%7B400%7D%7B250%7D%5C%5C%5C%5C%5CRightarrow%20R%3D1.6)
option (b) is correct
