Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (3, 9) and (x₂, y₂ ) = (- 2, 8)
m = = =
Answer:
-1, -1
Step-by-step explanation:
Answer:
x = 2 , y = 11
Step-by-step explanation:
the diagonals of a parallelogram bisect each other , then
PT = TR , that is
y = 5x + 1 → (1)
QT = TS , that is
2y = 6x + 10 → (2)
substitute y = 5x + 1 into (2)
2(5x + 1) = 6x + 10
10x + 2 = 6x + 10 ( subtract 6x from both sides )
4x + 2 = 10 ( subtract 2 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
substitute x = 2 into either of the 2 equations for corresponding value of y
substituting into (1)
y = 5(2) + 1 = 10 + 1 = 11
Answer: <em><u>ratio</u></em>
(a Rational number is a number that can be written as a <u>ratio</u> of two integers)
Step-by-step explanation:
By definition a Rational number is that number that can be expressed as a fraction:
Where the numerator "a" is an integer and the denominator "b" ()
Then, in other words, a Rational number is a number that can be written as a ratio of two integers.
Since the denominator "b" can be , we know that every Integer is a Rational number.
Below are some examples of Rational numbers:
