My apologies on answering late...
Same situation as the previous problem, but this time, all you need to do is state the degree of the angle instead of just providing the angle itself.
ΔABC ≅ ΔDEF
Now, we can see that ∠C ≅ ∠F. Using this information, we can find ∠C on the first triangle ( which is 
° ).
Since ∠C ≅ ∠F,
m∠F is °.
Hope I caught your question in time!
Have a good one! If you need anymore help, let me know.
Answer:
An equation for the inverse variation y = 2 when x = 5 is:
y=10/x
Step-by-step explanation:
Suppose that y varies inversely with x:
y=k/x
Write an equation for the inverse variation y = 2 when x = 5
Substituting y by 2 and x by 5 in the formula above:
2=k/5
Solving for k: Multiplying both sides of the equation by 5:
5(2)=5(k/5)
10=k
k=10
Then the equation is:
y=k/x
y=10/x
Yes this is true. Very true
Answer:
y=-x^2
Step-by-step explanation:
given that y = x^2 is the function.
For equivalent to -y, we can multiply this equation both the sides by -1
We get -y = -x^2
Hence option G is right.
Also y =x^2 is a parabola with vertex at origin open up.
Hence if F is selected we get -y =(-x)^2 = x^2, this will make the parabola open down and hence this option is wrong.
H: -y=-x is wrong because this represents a line but we had original equation as that of a parabola
J) -y = x^(-2) means x^2y =-1
This implies that rate of change of y = 2/x^3 but rate of change of y has to equal 2x since y = x^2 is original. Hence only option G is right.
