Answer:
True
Step-by-step explanation:
The equation of direct variation is
y = kx ← k is the constant of variation
To find k divide both sides by x
= k
That is the constant is the ratio of y- values to x- values
Answer:
Step-by-step explanation:
Verifying pairs:
(1,0)
- 0 = 6*1 - 2
- 0 = 4 - incorrect
(5, 28)
- 28 = 6*5 - 2
- 28 = 30 -2
- 28 = 28 - correct
(6, 20)
- 20 = 6*6 - 2
- 20 = 36 - 2
- 20 = 34 - incorrect
(3, 19)
- 19 = 6*3 - 2
- 19 = 18 - 2
- 19 = 16 - incorrect
I took geometry a while ago, I can help if you want.
Answer:
longest side=3.6
let ratio 3:5:6:9be 3x,5x,6xand9x
perimeter= sum of all side
9.2=3x+5x+6x+9x
9.2=23x
x=9.2÷23
x=0.4
9x=9×0.4=3.6
6x=6×0.4=2.4
5x=5×0.4=2
3x=3×0.4=1.2
