Answer:
x = (-1,-3) y = (5, -1)
Step-by-step explanation:
there's your equation.
To compare whether or not two fractions are equivalent, they must have the same denominator.
What is a common denominator you can make between
and
? Some possible options are 5n or 10n.
I'll make both denominators 5n:1)
already has 5n in the denominator.
2) To get 5n in the denominator for
, you want to divide both the numerator and denominator by 2 (same as multiplying top and bottom by
). Since you're doing the same thing to the numerator and denominator, you are not changing the value of the fraction:
Now
compare the two fractions. Since
, your fractions are equivalent!

Answer: They are equivalent
If two numbers are proportional, it means that they are equal.
Example:
30/2 = 15
F(x)=x^2 - 4x - 4x +16-16-9
=x(x - 4) -4(x - 4) - 25
= (x-4)(x-4) -25
f(x)=(x-4)^2 - 25
the vertex is (4, -25)
the vertex occur at
x = - b/2a and y = (4ac - b^2)/4a
x= - - 8/(2*1)=4
y=[4*1*(-9) - (-8)^2]/(4*1)
= (-36-64)/4 = - 100/4 = - 25
Answer:
Theres quadrants so -3,9 would be lower about III
6,-6 would be IV
0,-1 1/2 That would be near the 0 obviously so II
