Answer:
-6/7
Step-by-step explanation:
The slope of the line perpendicular to DE is the negative reciprocal of the slope of DE. The slope of DE is ...
(change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6
The inverse of that is 6/7, and the opposite of that inverse is -6/7.
The slope of the line perpendicular to DE is -6/7.
Answer:
.093
Step-by-step explanation:
do
1.00-0.07
Answer:
(P) =360
(l) =?
(b) =?
so, let the breadth be x
let the length be 2x
Perimeter of rectangle=2(l+b)
360 =2(2x+x)
360/2 =2x
180/2 =x
60 =x
x =60
ATQ
Breadth = 60
length= 60 ×2
=180
Answer:
200-5x and 90
Step-by-step explanation:
we don't know how many weeks she spent at first so we make the equation 200-5x
and then it would be 5x22 which is 110
so 200-110=90
Answer:
Option 4.) month 4
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (3,27)
That means -----> For x=3 months, the populations in both functions are the same (the bacteria populations is 27)
therefore
For x> 3 months the f(x) population is greater then the g(x) population
