d1 = ax + by + c = 0 and d2= mx + ky + f = 0
if they are parallel :
8x + 2y = 7
8x + 2y - 7 = 0
- 8x + 2y -9 = 0
- 4x + y -6 = 0
- 16x + 4y - 19 = 0
you can create more whatever you want =)
Hope this helps ^-^
Let write these numbers into fractions. miles/time
You: 2/1
Your friend: 3/24= 1/8
You are running faster because you are 16 times faster
Answer:
4x²+13x+9
iwill give you good method to simplify this
firstable take the 4 from x² and multiply it by 9
x²+13x+36
we find this equation
so the values is 4 and 9 because 4+9=13
4×9=36
(x+ )×(x+ )
first we take 9 and devide it by 4
9/4 the four for the x and the nine is number
so its will be
(4x+9)×(x+ )
same thing with 4 devide by 4 so the value is 1
so its will be like this
(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
