According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:
x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
Answer:
The Inequality For determining number of equation written by Mustafa for school paper is .
Mustafa has written more than 8 articles.
Step-by-step explanation:
Given:
Combined Total Number of articles = 22
Let the number of articles written by Mustafa be 'x'.
Now Given:
Heloise has written as many articles as Mustafa has.
Number of article written by Heloise =
Gia has written as many articles as Mustafa has.
Number of article written by Gia =
Now we know that;
The sum of number of articles written by Mustafa and Number of article written by Heloise and Number of article written by Gia is greater than or equal to Combined Total Number of articles.
framing in equation form we get;
Hence the Inequality For determining number of equation written by Mustafa for school paper is .
Now Solving the Inequality we get;
Taking LCM for making the denominator common we get:
Hence Mustafa has written more than 8 articles.
Answer:
Therefore the required value of x,
Step-by-step explanation:
Given:
ΔBC is a Right Angle Triangle at ∠ B = 90°
As ∠ B = 90° , AC will be the Hypotenuse
AC = 10 = Hypotenuse
BC = y = Longer leg ( say )
AB = x = Shorter leg ( say )
To Find :
x = ?
Solution:
In Right Angle Triangle Δ ABC , By Pythagoras Theorem we get
Substituting the given values we get
Therefore the required value of x,
