Answer:
y-9=1/2(x-8)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-9)/(-2-8)
m=-5/-10
m=1/2
y-y1=m(x-x1)
y-9=1/2(x-8)
Answer:
25/12
Step-by-step explanation:
1/2 + 2/5s = s - 3/4
2/5s = s - 5/4
-3/5s = -5/4
s = 25/12
(1/A) dA/dt= C where A is the population of ants and C is a constant
ln(A) = C*t + C1 where C1 is another constant that comes out of integration and t is time in days.
Plugging in: at t=0, A= 100 so C1 = ln(100) = 4.605
at t=3, A=230 so ln(230) = 3*C +4.605 so C = 0.278
Final equation:
ln(A) = 0.278t + 4.605
or:
A = exp(0.278t + 4.605)
After 14 days, A = exp(0.278*14 + 4.605) = 4875.2
Answer:

= 60
60 km/h
The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
