Answer:
the last one I think sorry if its incorrect
Answer: a. Yes
Step-by-step explanation:
Let the opposite side =12
Let the adjacent side = 16
Let the hypotenuse side =20
Using the pythagoras theorem
we are going to prove that hypotenus is 20
opp² + adj² ⁼ hyp²
12² + 16² ⁼ hyp²
144 + 256 = hyp²
400 = hyp²
√400 =hyp
20= hyp
Therefore hypotenuse= 20
We are told that y varies directly with x.
Therefore
y = k*x
where
k = the constant of variation
The given table and the ratio of k=y/x is shown below.
x y k
--- ------ --------
6 10 1.667
9 15 1.667
12 20 1.667
15 25 1.667
Answer:
k = 1.667
y = 1.667x

Answer:
The graph of y2+3x=0 is symmetric with respect to the x-axis
Step-by-step explanation:
To establish symmetry with respect to the x-axis we simply substitute -y in place of y in the original equation. If the resulting equation is identical to the original one then the function is said to be symmetric with respect to the x-axis.
In this case we have;
Which is identical to the original equation
