(0,3)(1,9)
slope = (9 - 3) / (1 - 0) = 6/1 = 6
y = mx + b
slope(m) = 6
use either of ur points...(0,3)...x = 0 and y = 3
now sub and find b, the y int
3 = 6(0) + b
3 = b
ur equation is : y = 6x + 3
for an inequality, a dashed line means there is no equal sign in the problem...and shading above the line means greater then.
so ur inequality is : y > 6x + 3
Answer:
60
Step-by-step explanation:
If all triangles equal 180 degrees, then all you have fo do is divide 180 by the number of points a triangle has
The value of x is 2x+38=90
The answer is x=26
Answer:
16,460 gallons
Step-by-step explanation:
This is a differential equation problem, we have a constant flow of contaminant into the lake, but also we know that only a fraction of that quantity of contaminant remains because of the enzymes. For that reason, the differential equation of contaminant's flow into the lake would be:

Then, we have to integrate in order to find the equation for Q(t), as the quantity of contaminant in the lake, in function of time.

Now, we use the given conditions to replace them in the equation, in order to solve for

Then, we reorganize the equation and we replace t for 17 hours, in order to determine the quantity of contaminant at that time:

Answer: Hope this helps you
