# Write an equation where y varies directly as x Y=kab is the equation ^_^ elaineeee
the equation is y=kx Formula for solving that equation is
y=kx find k then substitute k to check the equation if it is equal batopusong81
EQUATION: y = kx

28 = k(7) = *Where k is the constant kurtiee

1. y= 28 when is x=7  y=kx 28=k(7) 28=7k       ...divide 28 by 7 k=4  Hence, the equation is y=4x  2.y=30 when x=8  y=kx 30=k(8) 30=8k          ...divide 30 by 8 k=15/4  Hence, the equation is y=15/4x   3. y=0.8 when x=0.4  y=kx 0.8=k(0.4) 0.8=0.4k         ...divide 0.8 by 0.4 k=2  Hence, the equation is y=2x.

Step-by-step explanation:

10000000000+2000000000 homersoncanceranguiu
1. k= 28/7=4
y= 4x

2. k= 30/8 = 15/4 or 3 3/4
y=3 3/4x

3. k= .7/.4 = 7/4 or 1 3/4
y= 1 3/4x

4. k= .8/.5 = 8/5 or 1 3/5
y= 1 3/5x

5. k= 400/25 =16
y= 16x

6. k= 63/81 =7/9
y= 7/9x

7. k= 200/300 =2/3
y= 2/3

8. k= 1/2
y= 1/2x

9. k= 48/6 =8
y= 8x

10. k= 10/24 = 5/12
y= 5/12x JUMAIRAHtheOTAKU
1)
Y=kx
12=3k
3k/3=12/3
k=4
Y=4x
Y=4(12)
Y=48
2)
A=kb
5=1k
1k/1=5/1
k=5
A=5b
2=5b
5b/5=2/5
b=0.4 kenn14
THE EQUATION IS: y = kx  ### Other questions on the subject: Math Math, 28.10.2019, snow01
