Write the equation of the line that has a slope of -4 and goes through (3,-3)
Sindrei [870]
The functional equation of the line is f (x)=a*x+b
you have already a: -4 -->f (x)=-4 x+b
Now you can use the point (3;-3)
3 is the x-coordinate and -3 the f (x)-coordinate
--> -3 = -4*(3) + b Now you can solve it
-3 = -12+b (+12)
b = 9
ANSWER: f (x) = -4x + 9

The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t&gt; or =0 is measured in weeks. C
butalik [34]

Answer:

The average rate of change is \frac{18}{5}

Step-by-step explanation:

Given function that shows the population of a culture of cells,

P(t)=\frac{90t}{t+1}------(1)

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

m=\frac{P(24)-P(0)}{24-0}

From equation (1),

=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}

=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}

=\frac{2160}{25\times 24}

=\frac{2160}{600}

=\frac{18}{5}
