Answer:
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
Divide both sides by 11
We have the final answer as
<h3>x = 8</h3>
Hope this helps you
Answer:
The Given situation is In 2005, the shabelle river in Somalia rose an estimated 5.25 inches every hour for 15 hours.
Increase in water level is represented by the function,f(x)=5.25 x.
or replacing f(x) by y we get ,y= 5.25 x
This is equation of straight line passing through the origin.
As x is number of hours , so x> 0,(0,∞] Which is it's domain.
As x> 0, so Range is those values of y for which x is defined.
,So Range is y>0 i.e (0,∞}
As the function has no breaking point , that is when you plot the graph on coordinate axis there is no breaking point.So , it is everywhere continuous i. e for all values of x.
B-5
1/5 of 200 would be 40, 1/2 of 40 is 20, 1/4 of 20 is 5. Hope this helps!
Mark 2 points on the coordinate grid and draw a line through them
One point would be when x = 0 and y = 1/2(0) + 5 = 5.
and another point is ( 10, 10)
