Answer:

C. The total number of bacteria present in the sample after 2 hours is 12.

Step-by-step explanation:

If f(x) is the total number of bacteria present in a sample and x is the number of hours, then the meaning of f(2) = 12 is that the number of bacteria present in the sample is 12 after 2 hours.

When you replace the x for 2, it ends up in f(2), that’s the number of bacteria in the sample after 2 hours, then the function says that f(2) =12, therefore the number of bacteria after 2 hours is 12.

Find midpoint (-6, 3) (4,-3)

Crank

<h2>Coordinate of mid point = (1,0)</h2>

Step-by-step explanation:

Given points are (-6,3) and (4,-3)

$x_1=-6 ,$ $y_1=3$ , $x_2= 4$ and $y_2 = -3$

Coordinate of mid point $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

$=(\frac{-6+4}{2} ,\frac{3+(-3)}{2})$

=(1,0)

I'm confused- how do I form the equation with 2 pts?

klio [65]

Answer:

the equation of the line is y = -3x - 6

Step-by-step explanation:

Note that since (0, -6) is the y-intercept, we can write the slope-intercept equation of the line as y = mx - 6. The other given point is (-2, 0) (which happens to be the x-intercept also). Starting with y = mx - 6, replace y with 0 and x with -2:

0 = m(-2) - 6. We now solve this for the slope, m: 0 = -2m - 6 becomes

2m = -6, or m = -3.

With m = -3 and b = -6, the equation of the line is y = -3x - 6
