For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.
Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5
The answer will be 625j^4 k^4
Answer:
65 deg
Step-by-step explanation:
Recall that interior angles of a triangle must add up to 180 deg.
hence
x + 68 + 47 = 180
x = 180 - 68 - 47 = 65 deg
90 = k*15
constant of proportionality = 80 / 15 = 6 Answer
