Answer: (0.5, 8.5)
Step-by-step explanation: (9+-8/2) is 1/2 and (7 + 10/ 2) is 8.5. After plugging it into the equation, I checked with a graphing site.
Let's use pi
irrational times rational=irrational
pi≈3.14
so double that is
2pi≈6.28
that's beteween 5 an d7
so an irrational number between 5 and 7 is 2pi
we could also do
remember that square roots of non-perfece square numbers are usually irraitonal
5²=25
7²=49
so an irrational number could be √c where 25<c<49
example, √40
some irrational numbers are 2π nd √40
Parallel lines will have the same x value.
X^2 - 6x + 40 = x + 5
Solution for quadratic equation
Subtract 40 from both sides.
x^2 - 6x + 40 - 40 = x + 5 - 40
= x^2 - 6x = x - 35
Subtract x from both sides.
x^2 - 6x - x = x - 35 - x
= x^2 - 7x = -35
Rewrite the equation in the form
(x + a)^2 = b
(x - 7/2)^2 = - 91/4
Answer
x = 7/2 + sqroot 91/2,
x = 7/2 - sqroot 91/2
Solution to simplify
Group like terms
x^2 - 6x + 40 = x + 5
x^2 - 6x - x = 5 - 40
x^2 - 7 = -35
Answer: triangles are similar.
Step-by-step explanation:
Givn : OK = 3, OJ = 30, KN = 1, JM = 3#
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means
That means the three angles of triangle OKJ are equal to the corresponding three angles of triangle ONM.
Hence the to triangles are similar.
