Answer:
A
Step-by-step explanation:
the equation representing quantities that vary directly is
y = kx ← k is the constant of variation
given
4y = 2x ( divide both sides by 4 )
y = x
which represents direct variation with k = → A

Answer:
x^7/6
Step-by-step explanation:
(x^5/6)(x^1/3)=x^(5/6+1/3)=x^(5/6+2/6)=x^7/6
Answer:
x>2 and x<10
Step-by-step explanation:
Using Triangle Inequalities, this is the ranges because when x is greater than 2 and less than 10, a triangle is always possible and forms.
Answer:
x = 9
Step-by-step explanation:
The sum of interior angles in a triangle is 180°.
Let's say the measure of the angles are 3x, 10x, and 7x.
3x + 10x + 7x = 180
20x = 180
<u>x = 9</u>
