Answer:
x-2y=0 is a direct variation
Step-by-step explanation:
Direct variation is of the form
y= kx
Can we get the equation in that form
x-2y =0
Add 2y to each side
x-2y+2y =0_2y
x=2y
Divide each side by 2
x/2 = 2y/2
1/2x =y
Flip the sides
y = 1/2x
This is of the form y= kx where k = 1/2
x-2y=0 is a direct variation
Answer:
3916.6
Step-by-step explanation:
Answer: 199,990
Step-by-step explanation:
You can't round to the nearest tenth because you don't have a decimal added to the number.
I rounded to the nearest tens and got 199,990
Answer:
9120
Step-by-step explanation:
I'm assuming you mean LCM (Least Common Multiple).
Factor each number into powers of primes.
76 = 2²×19
96 = 2⁵×3
120 = 2³×3×5
Take the highest power of each prime used: 2⁵, 3, 5, 1
The LCM is their product: 2⁵×3×5×19 - 9120
