Answer:
C. y=-4x-10
Step-by-step explanation:
The equation for a line in slope-intercept form is:
y=mx + b
m: slope
b: y-intercept
x,y: x and y coordinate pair
So the answer would be...
y=-4x-10
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000
Growth rate = r = 150% = 1.50
The equation model for this situation is:

Using the values in above equation, we can write:
This means, the person will fall sick after about 14 hours.
Answer:
56 gallons
Step-by-step explanation:
When her gas tank is full, she has x gallons in the tank.
when she went to the gas station, she had (5/8) of x gallons of gas in her tank. she added 21 gallons into her tank, then she had x gallons in her tank.
(5/8)x + 21 = x
subtract x and 21 from both sides
(5/8)x - x = -21
factor out an x from the left side
x(5/8 - 1) = -21
simplify the parenthesis
x(-3/8) = -21
multiply both sides by -8/3
x= 56 gallons
