(2/3) x + (2/5) x
(10/15)x + (6/15) x = (16/15) x
Answer:
Product of two expression is 
Step-by-step explanation:
Given : Expression - 
and 
To find : The product of given expression
Solution : To find the product we apply distributive law
We write in the form of product and multiply term by term
Apply distributive law,
Therefore, Product of two expression is
Answer:
first person has a chance of 7/28 or 1/4
The second = 6/27 or 2/9
The third = 5/26
And the fourth = 4/25
multiplying these together you get 4 / 2340=
1/585
or 0.17%
Rearrange the equation into slope intercept form
7x+3y=18
3y=-7x+18
y=-7x/3+18/3 so the slope of the reference line is -7/3
To be perpendicular to this line the slope must be the negative reciprocal of this...mathematically m1*m2=-1. So the slope of our perpendicular line is:
-7m/3=-1
-7m=-3
m=3/7 so our line so far is:
y=3x/7+b, using point (6,8) we can solve for b, the y-intercept
8=3(6)/7+b
8=18/7+b
56/7-18/7=b
38/7=b so our line is:
y=3x/7+38/7 or if you prefer
y=(3x+38)/7
