The value of constant of variation "k" is
Solution:
Given that the direct variation is:
y = kx ----- eqn 1
Where "k" is the constant of variation
Given that the point is (5, 8)
To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1
Thus the value of constant of variation "k" is k = 8/5 or 1.6
I hope this is correct and helps!

X^2 +12x-7x-84
x^2+5x-84. <- answer
Answer:
Step-by-step explanation:
Two angles that are directly across from each other when two lines intersect are called vertical angles. Vertical angles are ALWAYS congruent to each other. Very good thing to know when it comes to proving triangle congruency.
3.4^2-2.2^2×4.6-3.5×10.5 would be the simplified expression.
Note that ^ is an exponential sign.
Hope it helped,
Happy homework!
