Which statement can be made about a line in slope-intercept form when the graph of the line appears to slant downward from left
to right?
2 answers:
Answer with explanation:
The equation of line in Slope intercept form is:
⇒ y= m x +C
y= x tan (Angle made by line with positive Direction of X axis) +C(Y-Intercept)
It is given that, graph of the line appears to slant downward from left to right.
⇒It means ,the angle that the line is making with X axis should be:
90°<Angle<180°
as i have drawn the line about the given information.
⇒Tan (90°< Angle <180°)= Negative
So, we can say that slope of line will be Negative.

Answer:
The number of bacteria after will be
Step-by-step explanation:
Given the initially 30 bacteria present in the culture.
Also, the number of bacteria got doubled every hour.
So, using the equation
Where is number of bacteria after
hours.
is bacteria present initially.
is the common ration, in our problem it is given that bacteria doubles every hour. So,
And is the number of hours. In our problem we need amount of bacteria at the end of
hours. So,
Plugging values in the formula we get,
So, number of bacteria after will be
